[osg-users] problem with quadro cards database pager / terrapage terrains = black tiles
Hi all, Has anyone experienced problems with quadro cards and large terrains? I'm loading a pretty big (~8gb) terrapage file (using Delta3D 2.3.0 which i think is built against osg 2.8.0), and on a standard nvidia card it works fine. Using exactly the same software, i've tested it on two different machines with quadro cards and I get a combination of missing tiles or tiles appearing black (but with a changing alpha value depending on camera orientation). At different LODs the black tiles will change to a proper tile, but if the tile was though to be missing it will never load in. It's not always the same tiles causing the problem, and it almost seems that if i quit the app and re-run it up then the problem is less. its really unpredictable. have tried turning all the graphics card options (e.g. anisotropic filters etc) off and on and neither makes much difference. The card has 512mb memory on it so wouldn't have thought that would cause a problem... Really confusing!! Any thoughts gratefully received!!

Re: [osg-users] [osgOcean] 3D model material display error!
Hi Jan, Tian,
osgOcean uses shaders for pretty much every effect in the scene -
fogging, depth of field, glare, lighting etc. If objects that are
added to the scene are to look consistent with the ocean effects they
will require a shader to be applied that takes into account these
effects. This is particularly necessary if the fullscreen effects are
used as they require the alpha component of the frame buffer to work.
In order to address this issue, OceanScene will apply a default shader
to objects added as children (default_scene.frag vert) which
illustrates how to use the uniforms supplied by osgocean (prefixed
osgOcean_* ) in conjunction with your own shader. Since I could not
anticipate the many wierd and wonderful ways that shaders can be used
it only offers a very basic implementation (1 texture unit, limited
phong lighting etc) and should be seen as a shader to customise and
build on yourself.
You can override the default shader either by attaching a new program
to the object you wish to use in the scene or by using this function
in OceanScene:
/** Override the default scene shader for custom shaders.
* If custom shaders are required for individual nodes add them
before adding to the OceanScene.
* Dirties state.
*/
void setDefaultSceneShader( osg::Program* program )
{
_defaultSceneShader = program;
_isDirty = true;
}
Alternatively you can turn the default shader off completely with
setter in OceanScene.

Kim.

Re: [osg-users] problem with quadro cards database pager / terrapage terrains = black tiles
Hi Vins, I am running Delta3D terrain simulation VPB built terrain on some quadro card on Linux 64-bit system without any trouble... But it might be different, as I've not such big database as you are talking about and the terrain is not a terrapage file. Does the problem only occur on very large database ? What is your standard card vs Quadro card ? What is your driver version ? what is your system ? If it is not a driver related problem, it might be a problem with some VBO/PBO functions... Pierre.

Re: [osg-users] Databasepager + multiple views + different camerapositions = memory leak?
Hi Sergey, Have you tried to read DB with CACHE_NONE options ? Its really blind shot, and I will most probably miss, but its easy to test, so thought I would let you know about this. We have recently dealt with PageLOD leak problem. Database was build using our proprietary tools. However, this DB is very similar to VPB databases. It turned out that object cache was involved into equation. We had to remove CACHE_NODES flag from options to prevent the code from memory leaking. I am not sure what are mechanics of this problem, and if we always had this problem or it started to be nastier when we added some more detail. Butt we noticed this recently and had to make workarounds. One may say that default DB options do not include CACHE_NODES flag, so most probably do not affect your case, but I noticed that defaults have set CACHE_ARCHIVE and TXP are treatead as archives, so I thought I would let you know about this.

Then I received a series of errors when trying to compile it, so I moved some input and .lib files around and finally got it to build.

Re: [osg-users] [osgOcean] Error used osgOcean1.0 in MFC vc2005sp1
Hello Tian,
Was it those that you deleted? Yes, I just delet thems, because I found that these two
inline functions had not been used in anywhere. And now my project just goes right,
the same with the oceanExample.
Sorry I didn't pick up on this thread... I'm pretty darn busy so I just
glance over threads that I don't immediately have an answer for, but
looking at the OceanScene header in the osgOcean-1.0 tag, lines 213 and
223, it was immediately obvious what the problem was. You do not need to
delete them. Just rename the variables called near and far to
something else, like this for example:
/** Set near DOF blur distance.
* Updates the uniform is DOF state is valid.
*/
inline void setDOFNear( float zNear ) {
_dofNear = zNear;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Near)-set(_dofNear);
}
/** Set far DOF blur distance
* Updates the uniform is DOF state is valid.
*/
inline void setDOFFar(float zFar ) {
_dofFar = zFar;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Far)-set(_dofNear);
}
Just for general reference, the problem was that on Windows compilers
(and previously DOS), near and far were once keywords used to refer
to memory inside the first 64k page, and outside, respectively (back
when you needed to address them differently, which is a long time ago).
Nowadays it's pretty obsolete, but some compilers on PC still carry that
legacy. And I get bitten by it every time I do OpenGL or raytracing code
that needs to have a frustum, with near and far planes :-)
And it doesn't matter that these methods are not used in osgOcean or the
oceanExample themselves, they're still useful methods to have in order
to be able to tweak osgOcean's rendering.
Sorry , I did not know the meaning of the trunk update clearly.
Kim meant checking out from
http://osgocean.googlecode.com/svn/trunk/
instead of
http://osgocean.googlecode.com/svn/tags/osgOcean-1.0/
The 1.0 tag is pretty old now, people should not check out using it
anymore... Kim, is it possible to make changes on the googlecode site so
that it doesn't show up by default when people click on the source
tab? The default checkout should be from the trunk now. And the trunk
has the above fix already, btw.
Hope this helps,
J-S

Hi Jan, All the frame buffer objects in osgOcean use texture rectangles so it simply passes them directly to the texture/camera setups, so there shouldn't be any limit.

Re: [osg-users] [osgOcean] 3D model material display error!
Hi MT,
For the reasons I just gave, you can't add objects to the scene and
have the full compliment of effects without either using the default
shader or using your own shader implementation.
Reflections/refractions etc will continue to work since they act on
the ocean surface and not the model. However, other such as glare,
depth of field, light scattering, fogging etc will not as they act on
the models themselves.
However, it is pretty straight forward to duplicate a subset of fixed
pipeline functionality within a shader and then add the relevant
osgOcean shader effects to it, you can just copy functions from the
default shader and mix them in with the result of your shader.

Re: [osg-users] PagedLOD experts?
Hi Chris, It does raise another question -- is this a common practice and is there anywhere else in OSG where node name has a special meaning during specific phases of operation? I tend to think that any use of user-settable properties, such as node name, callbacks, user data, etc. inside OSG is potentially dangerous. Any app could potentially change the node's name, remove/replace a callback or user data and that would break the library's behavior, and the only way to know why it's broken is to go delve into OSG's source. For callbacks, it's pretty easy to instead derive a node type and override the traverse() method. That way it's much harder for the user to break expected behavior of the node (they would need to derive from this node type, override traverse() and forget to call the base class version). For name and user data, I don't see an easy way to avoid using them if OSG already uses them in some cases... But in any case, identifying nodes by name always strikes me as unsafe. Since we use visitors so often in OSG coding, OSG itself can't assume that any node is hidden from the user, and so can't assume that user-settable properties won't be changed by the user... This doesn't really help you, but I wanted to be more detailed than just saying I agree.

Re: [osg-users] [osgOcean] Error used osgOcean1.0 in MFC vc2005sp1
J-S,
Just for general reference, the problem was that on Windows compilers (and
previously DOS), near and far were once keywords used to refer to memory
inside the first 64k page, and outside, respectively (back when you needed
to address them differently, which is a long time ago). Nowadays it's pretty
obsolete, but some compilers on PC still carry that legacy. And I get bitten
by it every time I do OpenGL or raytracing code that needs to have a
frustum, with near and far planes :-)
Ah interesting, nothing to do with windows.h then.. either way it
was fixed a while ago.
The 1.0 tag is pretty old now, people should not check out using it
anymore... Kim, is it possible to make changes on the googlecode site so
that it doesn't show up by default when people click on the source tab?
The default checkout should be from the trunk now. And the trunk has the
above fix already, btw.
Since there has been some additional functionality and lots of bug
fixes, I'll tag the trunk as a 1.05 or something and direct to that. I
think it's better to have people using a tag for download instead of
the trunk because things do get broken from time to time in there.
Cheers,
K.
2009/11/2 Jean-Sébastien Guay jean-sebastien.g...@cm-labs.com:
Hello Tian,
Was it those that you deleted? Yes, I just delet thems, because I found
that these two inline functions had not been used in anywhere. And now my
project just goes right, the same with the oceanExample.
Sorry I didn't pick up on this thread... I'm pretty darn busy so I just
glance over threads that I don't immediately have an answer for, but looking
at the OceanScene header in the osgOcean-1.0 tag, lines 213 and 223, it was
immediately obvious what the problem was. You do not need to delete them.
Just rename the variables called near and far to something else, like
this for example:
/** Set near DOF blur distance.
* Updates the uniform is DOF state is valid.
*/
inline void setDOFNear( float zNear ) {
_dofNear = zNear;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Near)-set(_dofNear);
}
/** Set far DOF blur distance
* Updates the uniform is DOF state is valid.
*/
inline void setDOFFar(float zFar ) {
_dofFar = zFar;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Far)-set(_dofNear);
}
Just for general reference, the problem was that on Windows compilers (and
previously DOS), near and far were once keywords used to refer to memory
inside the first 64k page, and outside, respectively (back when you needed
to address them differently, which is a long time ago). Nowadays it's pretty
obsolete, but some compilers on PC still carry that legacy. And I get bitten
by it every time I do OpenGL or raytracing code that needs to have a
frustum, with near and far planes :-)
And it doesn't matter that these methods are not used in osgOcean or the
oceanExample themselves, they're still useful methods to have in order to be
able to tweak osgOcean's rendering.
Sorry , I did not know the meaning of the trunk update clearly.
Kim meant checking out from
http://osgocean.googlecode.com/svn/trunk/
instead of
http://osgocean.googlecode.com/svn/tags/osgOcean-1.0/
The 1.0 tag is pretty old now, people should not check out using it

Re: [osg-users] Broken Textures in Recent OSG
Hi Wojtek, My guess is that texture coordinate output is getting corrupted for some reason. Looking at the .osg file it has a PER_PRIMITIVE color array which will force osg::Geometry to use slow paths, so perhaps this is a big buggy in certain combinations of array set up. Could you try removing the colour array from the .osg file and then have a look at the results, as this should get osg::Geometry back on fast paths. Unfortunately I have only have a GLES 2 build of the OSG on my dev machines right now, and GLES2 doesn't yet work well enough for me to do any diagnostics on things like osg::Geometry, so I won't be able to look into this problem right away. Once I've got a bit more of the GLES 2 port working I'll return to testing the standard GL build out and should be able to track down the issue with handling this model.

[osg-users] Refactoring DatabasePager NeedToRemove string flagging technique
Jean-Sébastien Guay wrote: This doesn't really help you, but I wanted to be more detailed than just saying I agree. Thanks for th insight, everyone. I'm kind of an old-school C-flavor programmer, so my instinctive response is rather C-like. I don't like bloating people's in-memory objects, so I'd lean towards defining a 32-bit flag member on class Node called something like _ephemeralInternalStateFlags. This would not be saved or restored, and the definitions of each flag bit would be enumerated as 1n enums in the Node class header. Code outside of the OSG core distribution would be prohibited (by policy, can't really enforce it in the compiler) from defining and utilizing these flag bits, but code within OSG core could. The first bit allocated would be used to replace the NeedToRemove indicator. Also, while the read-modify-write cycle used to toggle just one bit of a flag is not as fast as the blind-write cycle used when you dedicate a whole boolean variable (and consume more memory), both the setting operation AND the testing operation should be faster than the current string-marking technique. If Robert has no objections to this solution, I'll code it up quick and share it. I'm also concerned about the amount of very similar-but-not-quite-the-same code between DatabasePager::capped_removeExpiredSubgraphs and DatabasePager::expiry_removeExpiredSubgraphs. I'd like to refactor that to DRY (Don't Repeat Yourself) it out a bit as I'm implementing some code of my own that needs to cleanly dispose of some PagedLOD children. But, I don't understand why there are differences in the disposal technique between them (one calls _fileRequestQueue-updateBlock() directly, one sets a local flag and calls updateBlock() at the end of the operation, etc).

Re: [osg-users] Change to Optimizer OptimizationOptions
Paul Martz wrote: In Wojciech's modified submission, he changed the bitmask variable to a signed int, with the reasoning that enum values are also signed ints, and this eliminates the need for a typecast to get rid of compiler warnings. This caused me to weigh in with the workaround of declaring the bit values as static const unsigned int, and keeping the bitmask unsigned. But this goes against the OSG precedent set with the Optimizer. I see both sides here. My only input would be that some IDEs (VC++ among them, I believe) have better facilities for understanding and displaying constants defined as enums than as const variables. For example if I have an enum of FOO defined as 4, and I have a variable of the enumerated type containing 4, the debugger will display it to me as FOO (4) which is more meaningful than just (4). However, with bitmasks, you'll hardly ever have just a single bit set, so the IDE's enum interpretation ability kind of goes out the window. So, I'd lean towards whatever makes the cleanest reading and compiling code. It seems to me like this would be the static const unsigned int. No ugly casts when used, no ugly warnings when compiled. But if the same thing can already be achieved with the enum+signed technique, then I'm ok to leave well enough alone. If you could post with do it this way or do it that way, I (for one) could get back to work and stop prodding everyone with my code style opinions. :-) Ooh, we could start a whole new OSG list just for code style fights and then unearth the old extensionless headers arguments on the first day of each month just for fun!

Well, you're going to experience some grief being on such an old release. There are many bugs that have been fixed since 1.2, I'm sure. You will probably encounter them. Depending on your schedule, you might strongly consider trying to compile your codebase against a current OpenSceneGraph-2.8.2 release. We're going to be hard-pressed to help you with issues on such an old codebase. And, you're going to have to update at SOME point. I work for a Flight Simulation Company and we're generating a Tactical Map that is 1000kmx1000km. We generated 1879 Bitmaps at a resolution of 2MPP, and I'm using osgdem to generate an .ive database to be used by our software on a Flight Simulator we're currently building. It's currently been running for 7 days, and it's diving into the 11th Level, so I'm anticipating around 873,000 files to be generated, consuming approximately 175GB. I'm fine with the Disk Space as we're storing the DB (along with 4 others of similar sizes) on a 2TB drive. Ok. I was told by Robert Osfield to try using VPBMaster for this, but I can't get off the ground with it. He said 1879 files was too much to feed into OSGDem. However, my former co-worker wrote a method that handles an ARG_FILE as input to OSGDem and feeds it the parameters as necessary to execute them. I believe this method is doing what vpbmaster would do, if I could get it running. Do you have any thoughts all that? Well, I have no idea how your co-worker was using OSGDem. Is it anyone we'd know? Are you trying to compile an OSGDEM/VPB release from a modern VPB code checkout, or what version of the VPB code are you using? Your code ingredients here may be toxically immiscible. Thanks!

Re: [osg-users] Setting up VPBMaster
Thanks for the feedback, Chris. I'm trying to use VPBMaster-0.9.0 or VPBMaster-0.9.1 with OpenSceneGraph-1.2, so you're right, I'm not sure if they're even compatible. I'm only using this as a back-up option though. Robert said that osgdem can't handle a database as large as the one we're trying to generate, but it has been running for 7 days and seems to be processing all of the data. Do you know what the expected behavior is for osgdem if I pass in 1879 bitmaps and try to generate a 1000kmx1000km database at 2MPP (actually, the lower half of the DB is being generated at 4MPP(11 levels), and the upper half of the DB is being generated at 2MPP(12 levels))? My estimate is that OSGDem will finish processing the data in 8 more days and then begin generating the files (for approximately 9 more days). Do you think this will even work?

Well, you're going to experience some grief being on such an old release. There are many bugs that have been fixed since 1.2, I'm sure. You will probably encounter them. Depending on your schedule, you might strongly consider trying to compile your codebase against a current OpenSceneGraph-2.8.2 release. We're going to be hard-pressed to help you with issues on such an old codebase. And, you're going to have to update at SOME point. I work for a Flight Simulation Company and we're generating a Tactical Map that is 1000kmx1000km. We generated 1879 Bitmaps at a resolution of 2MPP, and I'm using osgdem to generate an .ive database to be used by our software on a Flight Simulator we're currently building. It's currently been running for 7 days, and it's diving into the 11th Level, so I'm anticipating around 873,000 files to be generated, consuming approximately 175GB. I'm fine with the Disk Space as we're storing the DB (along with 4 others of similar sizes) on a 2TB drive. Ok. I was told by Robert Osfield to try using VPBMaster for this, but I can't get off the ground with it. He said 1879 files was too much to feed into OSGDem. However, my former co-worker wrote a method that handles an ARG_FILE as input to OSGDem and feeds it the parameters as necessary to execute them. I believe this method is doing what vpbmaster would do, if I could get it running. Do you have any thoughts all that? Well, I have no idea how your co-worker was using OSGDem. Is it anyone we'd know? Are you trying to compile an OSGDEM/VPB release from a modern VPB code checkout, or what version of the VPB code are you using? Your code ingredients here may be toxically immiscible. Thanks!

Re: [osg-users] Setting up VPBMaster
Hi Jacob, However, my former co-worker wrote a method that handles an ARG_FILE as input to OSGDem and feeds it the parameters as necessary to execute them. I believe this method is doing what vpbmaster would do, if I could get it running. Actually vpbmaster does more than that, it allows you to distribute your generation tasks over a network of machines so that your total generation would take much less time. It's a bit too late for that now, but I expect that's the major benefit Robert had in mind when steering you towards vpbmaster. As for your problems, VPB releases are tied to OSG releases, so you need them to match. According to the VPB site, even very old versions of VPB (0.9.1) required at least OSG 2.2, so I'm not sure what VPB version matches OSG 1.2, and even if you can find it, I'm absolutely sure it won't have vpbmaster, as that appeared for VPB 0.9.2 as you can see by comparing these two links: http://www.openscenegraph.org/projects/VirtualPlanetBuilder/browser/tags/VirtualPlanetBuilder-0.9.1/applications http://www.openscenegraph.org/projects/VirtualPlanetBuilder/browser/tags/VirtualPlanetBuilder-0.9.2/applications Now, in the interest of full disclosure, I can tell you the hard way of doing things, just so you can choose yourself whether you want to upgrade your app to a recent OSG release or not... To be able to use vpbmaster and still load the resulting database into OSG 1.2, you will need to: 1. Compile a recent OSG (2.8 for example) 2. Compile a recent VPB (0.9.10 to match OSG 2.8 for example) 3. Generate your database using --POLYGONAL so that no osgTerrain rendering techniques are used, and generate it into .osg format instead of .ive format as that's not backwards-compatible 4. Optionally, you can then make a tool/script to reconvert all the .osg files to .ive using OSG 1.2's osgconv tool (there's a page on the VPB wiki about this, which hopefully will be obsoleted soon by Chris's submissions) I'm probably forgetting other options you'd need to specify when generating to make sure your resulting files are compatible with OSG 1.2. The resulting .osg files (assuming you don't do step 4) will be much larger and slower to load than the corresponding .ive files, and converting them to .ive (step 4) will take a long time (probably close to the same time that was needed to generate the database in the first place). So, in the process, you'll compile a recent OSG anyways, and you'll be disabling all the features that make that recent release worthwhile. You'll also be generating much more data, and spending more time doing so. And finally, we won't be able to help you much if the steps I've outlined above lead to more problems which I might not have anticipated. I don't know about you, but that sounds like a lose-lose situation to me. Now, you've already invested a lot of time generating the database you're doing right now, so keep that of course. But for next time you need to generate something like that, you might want to consider what I said above.

Re: [osg-users] [osgPPU] I have an OSG app to which I would like to add a second render pass...
Which plugin is exactly used, is actually not dependent on osgppu. It just uses osgDB to load an .avi file. In earlier versions of osg a quicktime plugin was used to play .avi files, right. I don't know exactly the version number, but in between there was a change to ffmpeg plugin. I am also not sure if ffmpeg is built on windows at all. So, if video example don't work, then just ignore it, if it is sufficient for you. It could be that you would require couple of additional libraries to built osg's video plugin on windows.

Re: [osg-users] Setting up VPBMaster
Chris, Thanks again for your input. I won't even bother with VBPMaster now unless I get approval to upgrade OpenSceneGraph. There is a lot of overhead and hoops to go through in order to make a change like that, so I'm compile this info and pitch it to management and let them make a decision. As far as the current process goes, I'm glad to hear that it might work. My biggest question was if this is too much data, when will osgem crash - during processing or during writing? Your right, I will be upset if it crashed during writing, because that means I've lost 15 days, and I could have been exploring the options of VBPMaster by updating OSG, if that even gets approved here. To answer your last question, you're exactly right. I'm taking a bunch of Openflight data with 3D terrain/textures/models and I'm just generating a 2D map to be displayed from the Bird's-Eye-View. Your comment about going about that the wrong way scares me, but also indicates that there's a better way? Could you shed some light on that? I would love to pursue a different approach if it's more feasible for what I'm doing. However, I do know that my former co-worker ran a series of smaller samples of this exact database, processing it at various levels, and it produced the desired result. At one point, he had an output of 22,000 files, generated at various resolutions, and the resulting .ive database is fully compatible with our software and displays the entire database. Now we're just trying to apply that process to the entire database at a higher resolution? Do you have an alternative suggestion? I'm really open to any quicker/more reliable solution. Thanks!

Re: [osg-users] Setting up VPBMaster
We received OpenFlight data from our customer for the map that we need to display on our software. The data consists of terrain data, texture data, and model data. The database is 1000kmx1000km. My former co-worker wrote a tool that renders all of this OpenFlight data and generates bitmaps from it (12000x12000 pixels). We are using a resolution of 4 meters per pixel for the bottom half of the database (mostly water), and a resolution of 2 meters per pixel for the upper half of the database). After his tool is done we have 1879 bitmaps and an args file that we pass into OSGDem to generate an .ive database which will be used by our database. He wrote a method and added it to our OSGDem project that takes the args file as an -ARGS_FILE argument and feeds OSGDem all of the bitmaps and their corresponding arguments. When this is done, we have a master .ive file with a number of subtile .ive files for each Level of Detail. In the samples my co-worker generated, the highest level was L8, and we were currently going to L10 or L11 (the output screen says Need to Divide X + Y for Level 10, so I'm assuming it's going to Level 11, and if L0 is one of those, then we've got 12 Levels). Our software then uses all of these .ives and the appropriate level of detail is displayed based on the current Zoom Level in our software (user-specified dynamically).

Re: [osg-users] How should I organize the scene graph to handle 2 million points and lines?
Hi, Thank you for your suggestions! I think the scribe effect is probably what I want for selection. You mentioned something about unreferencing data on the CPU side once it is uploaded. I am quite interested in this. Could you please give me more details? Honestly speaking, the 2 million points and lines are probably not the largest dataset I will encounter. During the last few days, I discovered that my viewer probably has an acceptable performance, but the large amount of memory that it uses is probably the main issue I need to deal with. If there are some ways that can reduce the size of the scene graph or cache inactive part of the scene graph on disk, I would like to give them a try. Thank you!

Re: [osg-users] layering of text and geometry in a 2.5D setup
I think I have solved the issue. It turns out that if I simply set a render bin index on all my nodes that contain an osgText, things work as expected. Surprisingly I don't need to set the osg::StateSet::OVERRIDE_RENDERBIN_DETAILS. I would assume this is normal behavior. I think my main error was to assume that osg preserves the order of nodes when depth testing is switched off. At the moment I have a unique z-value/render bin index on all of my nodes. It's a bit inelegant because I need to do reassign this z value to all my nodes whenever I add or remove nodes. I think I will try to assign this z value only within each geode. I think this is possible because render bins are nested. Not sure yet how this will work then with my ray intersection--how I can determine the order my widgets are hit by the ray ... anyhow i will try to report back if I have a good solution for making this a bit more elegant.

Re: [osg-users] Mac OS X Snow Leopard
Hey Paul, I just built osg 2.8.2 from scratch on 10.6.1 (snow leopard). I would be happy if we could roll a 2.8.3 release with the required patches. The patched files in question are attached. Is there anything else I can do to make this 2.8.3 release happen? It's also good to note that there is a bug in cmake 2.6 which has been resolved in the 2.8-0 preview release. The architecture is not set correctly in the xcode project files. this mean even though i386 is set in cmake the xcode project will be set to $(NATIVE_ARCH) which results in a 64-bit build.

Re: [osg-users] Mac OS X Snow Leopard
Thanks, not sure about a 2.8.3, but it's under consideration. Good to know you're interested. I understand you can build 2.8.2 against the 10.5 SDK and still run on Snow Leopard. My understanding is the changes to OSG for Snow Leopard will allow someone to build OSG against the 10.6 SDK, is that right?

(still figuring out how the mailing list is connected to the forum) hey paul, I needed to apply the patches for building osg against either SDK. It's not exactly clear to me which change in Snow Leopard makes this necessary.

Re: [osg-users] [osgOcean] Error used osgOcean1.0 in MFC vc2005sp1

Skylark wrote:
Hello Tian,
Was it those that you deleted? Yes, I just delet thems, because I found
that these two inline functions had not been used in anywhere. And now
my project just goes right, the same with the oceanExample.
Sorry I didn't pick up on this thread... I'm pretty darn busy so I just
glance over threads that I don't immediately have an answer for, but
looking at the OceanScene header in the osgOcean-1.0 tag, lines 213 and
223, it was immediately obvious what the problem was. You do not need to
delete them. Just rename the variables called near and far to
something else, like this for example:
/** Set near DOF blur distance.
* Updates the uniform is DOF state is valid.
*/
inline void setDOFNear( float zNear ) {
_dofNear = zNear;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Near)-set(_dofNear);
}
/** Set far DOF blur distance
* Updates the uniform is DOF state is valid.
*/
inline void setDOFFar(float zFar ) {
_dofFar = zFar;
if( _dofStateSet.valid() )
_dofStateSet-getUniform(osgOcean_DOF_Far)-set(_dofNear);
}
Just for general reference, the problem was that on Windows compilers
(and previously DOS), near and far were once keywords used to refer
to memory inside the first 64k page, and outside, respectively (back
when you needed to address them differently, which is a long time ago).
Nowadays it's pretty obsolete, but some compilers on PC still carry that
legacy. And I get bitten by it every time I do OpenGL or raytracing code
that needs to have a frustum, with near and far planes :-)
And it doesn't matter that these methods are not used in osgOcean or the
oceanExample themselves, they're still useful methods to have in order
to be able to tweak osgOcean's rendering.
Sorry , I did not know the meaning of the trunk update clearly.
Kim meant checking out from
http://osgocean.googlecode.com/svn/trunk/
instead of
http://osgocean.googlecode.com/svn/tags/osgOcean-1.0/
The 1.0 tag is pretty old now, people should not check out using it
anymore... Kim, is it possible to make changes on the googlecode site so
that it doesn't show up by default when people click on the source
tab? The default checkout should be from the trunk now. And the trunk
has the above fix already, btw.
Hope this helps,
J-S

Hi Kim:

Hi MT,
For the reasons I just gave, you can't add objects to the scene and
have the full compliment of effects without either using the default
shader or using your own shader implementation.
Reflections/refractions etc will continue to work since they act on
the ocean surface and not the model. However, other such as glare,
depth of field, light scattering, fogging etc will not as they act on
the models themselves.
However, it is pretty straight forward to duplicate a subset of fixed
pipeline functionality within a shader and then add the relevant
osgOcean shader effects to it, you can just copy functions from the
default shader and mix them in with the result of your shader.

Hi Jan,Kim:
Thank you a lot.
Kim, does it means that: I can never keep the models looks like what
they are before? And I have to program shaders for every loaded models, in
order to have reflect or other effects?
I want to know that: is there a simple way to make the models just look
like what they are?
Kim Bale wrote:
Hi Jan, Tian,
osgOcean uses shaders for pretty much every effect in the scene -
fogging, depth of field, glare, lighting etc. If objects that are
added to the scene are to look consistent with the ocean effects they
will require a shader to be applied that takes into account these
effects. This is particularly necessary if the fullscreen effects are
used as they require the alpha component of the frame buffer to work.
In order to address this issue, OceanScene will apply a default shader
to objects added as children (default_scene.frag vert) which
illustrates how to use the uniforms supplied by osgocean (prefixed
osgOcean_* ) in conjunction with your own shader. Since I could not
anticipate the many wierd and wonderful ways that shaders can be used
it only offers a very basic implementation (1 texture unit, limited
phong lighting etc) and should be seen as a shader to customise and
build on yourself.
You can override the default shader either by attaching a new program
to the object you wish to use in the scene or by using this function
in OceanScene:
/** Override the default scene shader for custom shaders.
* If custom shaders are required for individual nodes add them
before adding to the OceanScene.
* Dirties state.
*/
void setDefaultSceneShader( osg::Program* program )
{
_defaultSceneShader = program;
_isDirty = true;
}
Alternatively you can turn the default shader off completely with
setter in OceanScene.
Regards,
Kim.

Hi,

Yes, I have seen the same thing. I believe that the shaders applied by
osgOcean are responsible and are not passing the the vertex colors
along.
I have yet to check the shader code, though.
