[osg-users] TextureRectangle, PBO difference between 1.2 and 2.0
Hi Robert, As part of the task in moving our applications to OSG 2.0 I discovered there is a change in the behaviour of the API when binding an image with a PBO to a TextureRectangle. Using 1.2 we could set the image on the texture and then simply call setImage on the image object and the TextureRectangle would automaticaly update. Since moving to 2.0 we have to call dirty on the Image after the setImage call. This is not a big deal for me as it is an easy change to make but I thought this might not have been an intentional change. I had a quick look to see what this was the case but couldn't track it down. This is what the code looks like: //set things up image = new Image(); image-setPixelBufferObject(new PixelBufferObject(image)); m_YTexture-setImage(image); //the on update call... Vimage-setImage(0.5 * m_imageWidth,0.5 * m_imageHeight,1,GL_LUMINANCE, GL_LUMINANCE, GL_UNSIGNED_BYTE,VBuffer,Image::AllocationMode::NO_DELETE); //Since 2.0 we now also have to call the following for the texture to update Vimage-dirty(); As I said this is not an issue as such just thought you might have wanted the behaviour to be consistent between versions.

[osg-users] osgDotNet : Used from C#
Hi again, Thanks for all those answers ! Did you rebuild the osgWrappers/osgSim DLL? If that builds without error the osgDotNet generator should see your additions. Note that the build of the osgWrappers DLLs is not enabled in the default CMake configuration; you need to turn on BUILD_OSG_WRAPPERS. Well in fact, I didn't pay attention to the osgwrapper_osgxxx.dlls since I thought the input for the Generator was the cpp source files of the wrappers and not the built dlls. You're perfectly right about the CMake built .sln (make sure to call Rebuild Wrapper osgSim and not simply Build, since I left OFF the BUILD_OSG_WRAPPERS in CMake), anyway that's what I did yesterday, and had that DLL rebuilt indeed. I don't understay what goes wrong since I see - using Depends.exe for example - my additions' symbols inside the native osgSim.dll. The OPENSCENEGRAPH_X86_DIR variable is okay too. I don't get it for now... Virtual function invocation among wrappers, user-defined subclasses of wrappers, and native code works in all directions by virtue of the design of osgDotNet. This support also extends to hand-coded virtual function wrappers if their implementations mimic the auto-generated support code for virtual functions. Ok, that soothe my mind on that !! Knowing that, solving the operator wrapping problem becomes the right point to work on.. Take a look at the custom code items in the GeneratorConfiguration.cpp file in the osgDotNet generator source. That mechanism is used to insert arbitrary code into osgDotNet-generated wrapper classes, so hand-coded wrapper functions to support NodeCallback::operator() could be added there. I see, you're talking about the getCustomCode() thing. I may try something there... if I get to something clean enough I may submit it to the team.

Re: [osg-users] TextureRectangle, PBO difference between 1.2 and 2.0
Hi Brad,
This is a bug, there shouldn't be a change in behavior w.r.t Texture
updating and PBO's. The mechanism behind is much changed but the
behavior should be the same.
I have looked at the code and found the that setImage and many other
others are doing a ++_modifiedCount rather than calling dirty(). This
will be bypassing the new mechanism that keeps the PBO in sync. I
have just gone through Image.cpp changing all the ++_modifiedCount
case to dirty(). The modified file is attached. The change are also
checked in to SVN.
I have tested the change on a movie file on my box and its working
fine, where a couple of days ago it wasn't working it was just loading
the first frame. I assumed it was a bug in the xine-lib plugin,
but... now know it wasn't, and now is fixed thanks to you uncovering
the right rock :-)
Could you test it out and let me know how you get on.
Robert.

Re: [osg-users] How OSG support multicard rendering
Hi Lizheng, First up you need to split up the problem into single machine, multiple CPU/GPU and clustering of machines. The osgViewer library supports multiple CPU/GPU set ups out of the box. In fact in you run any of the examples it will be default querry all the available displays and open up the view across all of them and automatically run multiple threads/multiple contexts. Doing SLI/CrossFire relies upon the graphics drivers being set up for this type of rendering, it isn't really something the OSG can get involved in. The OSG doesn't not directly support clustering, there is a very simple example osgcluster that illustrates how you might use UDP packets to run a simple viewer across a network. For more complete solutions you need to look further afield to tools like Equalizer, Vrjuggler etc. Robert.

Re: [osg-users] osgDEM layers and CoordinateSystemNode
Hi Robert,
You don't say how you check for the CoordinateSystemNode as I suspect
this might be the source of your problem.
Very simple:
if((_osg_terrain = osgDB::readNodeFile(filename)))
{
/* check if coordinate system */
osg::CoordinateSystemNode* csn =
dynamic_castosg::CoordinateSystemNode*(_osg_terrain);
This result in csn == NULL;
Had a look at the .osg and indeed the CoordinateSystemNode is a child node
of the
MultiTextureControl node.

The v1.2 branch will be licensed under the OSGPL and available for free download. “Many clients have applications that use OSG v1.2.

[osg-users] Cullvisitor question
Hi Robert/others,
while stepping through some of my code in a debugger I stumbled across
the following in include/osgUtil/CullVisitor. (It can easily be found by
searching for zn;)
In both functions clampProjectionMatrix for Matrixf/d:
if (result)
{
znear = zn;
zfar = zn;
return true;
}
Is the setting of zfar to zn intentional? (I do not know the code good
enough to know.) If so, maybe a comment that explains why would be in
order?

I see, you're talking about the getCustomCode() thing. I may try something there... if I get to something clean enough I may submit it to the team.

Re: [osg-users] osgDotNet : Used from C#
Hi Christophe (again),
You're part of the way there: that code will handle calls from C# to C++.
You'll need to add code to the adapter and unknown object classes in the same
file to complete the support. Take a look at, for example, the generated
wrapper code for osg::Group::replaceChild for a model of what the code should
look like.
The GeneratedCode.uml file in the doc directory has some class and sequence
diagrams covering the design of the virtual function support if you'd like more
background. It can be viewed with StarUML.

Subject: [osg-users] osgDotNet : Used from C#
Continuing on that second issue (still trying to uderstand the first one) :
Virtual function invocation among wrappers, user-defined subclasses of
wrappers, and native code
works in all directions by virtue of the design of osgDotNet. This support
also extends to hand-coded
virtual function wrappers if their implementations mimic the auto-generated
support code for virtual
functions.
Well I managed to add the following code in osgDotNet's Osg's NodeCallback.cpp :
void NodeCallback::operator()(Osg::Node ^ node, Osg::NodeVisitor ^ nv)
{
___vtnp(this)-operator()(___vtnp(node), ___vtnp(nv));
}
and of course this one in osgDotNet's Osg's NodeCallback.h :
virtual void operator()(Osg::Node ^ node, Osg::NodeVisitor ^ nv);
Everything builds right and I can see the following addition :
Osg.NodeCallback.op_FunctionCall(Osg.Node node, Osg.NodeVisitor nv) from my C#
application which allows me to write my UpdateCB inherited from
Osg.NodeCallback, but in real time my UpdateCB.op_FunctionCall(...) isn't
called.
In fact, I don't see the mecanics that'd allow in the first place the osgDotNet
NodeCallback.operator()() to be called when native NodeCallback.operator()()
is...
Are you sure this use case works ?
Sorry for bothering with that, but I don't see any other way to manage to do
scenegraph update without having it colliding with cull and draw (at least in
osg = 2.0.0).

Re: [osg-users] Extended PSM
Hi, Mihai Radu wrote, The implementation that Vlad has on the site is based on Dx9, so to bring it to OSG it would need to be re-written in OpenGL. I'll take a look at the paper to see the math involved, and maybe Vlad's interested in getting involved in the re-implementation, I certainly am. From what I saw in the running demo, XPSM seems to have way less surface artifacts, so it's got my attention. i think it can be easily implemented based on some current OSG shadow map code. + you need to check right-left hand coordinates and row-vector\column-vector math issues. if you have any questions\problems feel free to contact me at [EMAIL PROTECTED] ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osgDEM layers and CoordinateSystemNode
Try the child below the MultTextureControl, this should be the
CoordinateSystemNode you are after.

Hi Robert,
You don't say how you check for the CoordinateSystemNode as I suspect
this might be the source of your problem.
Very simple:
if((_osg_terrain = osgDB::readNodeFile(filename)))
{
/* check if coordinate system */
osg::CoordinateSystemNode* csn =
dynamic_castosg::CoordinateSystemNode*(_osg_terrain);
This result in csn == NULL;
Had a look at the .osg and indeed the CoordinateSystemNode is a child node
of the
MultiTextureControl node.
Thanks Gert

Re: [osg-users] Cullvisitor question
Hi J.P,
Thanks for the pointer. The code is wrong, so I've fixed it. None of
the calling code was using the set values so the bug won't have
resulted in any downstream problems, but this doesn't mean a problem
might not have been introduced further down the line.
Robert.

Hi Robert/others,
while stepping through some of my code in a debugger I stumbled across
the following in include/osgUtil/CullVisitor. (It can easily be found by
searching for zn;)
In both functions clampProjectionMatrix for Matrixf/d:
if (result)
{
znear = zn;
zfar = zn;
return true;
}
Is the setting of zfar to zn intentional? (I do not know the code good
enough to know.) If so, maybe a comment that explains why would be in
order?

[osg-users] osgDotNet : Used from C#
You'll need to add code to the adapter and unknown object classes in the same file to complete the support. Take a look at, for example, the generated wrapper code for osg::Group::replaceChild for a model of what the code should look like. oops... I missed the ___NodeCallback_adapter and ___NodeCallback_unknown_object_ classes... The first one seems to deal with what puzzled me. Right on : it works !! It sounds like the generator may be picking up an old or wrong osgwrapper_osgSim.dll for some reason. If you set the environment variable OSG_NOTIFY_LEVEL to DEBUG before executing the generator it'll cause the OSG DLL loader to tell you exactly which wrapper DLLs are being loaded. Again you're right : the generator took the osgwrapper_osgSim.dll in the location pointed by my Windows Path, not by the OPENSCENEGRAPH_X86_DIR. Since I have multiple versions of OSG on the computer, you see the mistake... However that local OSG copy patching is just a a quick-and-ugly solution, as you wrote. I'll keep an eye on osgIntrospection roadmap and even try to see if I can help (even if I'm much more familiar with .NET System.Reflection and System.Attribute classes -- not responding portability issues, even if Mono exists -- to deal with interface discovering issues). Everything works perfectly well knowing that, thanks a bunch !! I think I get the whole thing now.

Just to clarify, I have added Paul Martz and Bob Kuehne to the writers list from http://www.openscenegraph.org/svn/osg/OpenSceneGraph/branches SVN directories which will allow them to create branches for each of the stable releases and then make 1.2.1, 1.2.2, 2.0.0 2.0.1 etc releases from these. No branches have yet been made, but when they are they'll be there alongside the trunk in same SVN respository. I will remain focused on SVN, the dev releases (2.1.x etc) and getting the first stable release out (i.e. 2.0, 2.2, 2.4 etc)., which Paul and Bob will handle the binary compatible point releases of the stable releases. Its also worth remembering virtue of the OSGPL license all changes to the core OSG have to be made publicly available and under the OSGPL. so this includes bug fixes. So keeping them public is not only a good thing for the community and the project as whole, its also a legal requirement.
