Re: [osg-users] osgdem and UTM terrain tiles...
You could try getting overlapping data, my experience is that if your input data have no overlaps it is likely to see artifacts on the boundaries. 2008/8/7 Tueller, Shayne R Civ USAF AFMC 519 SMXS/MXDEC [EMAIL PROTECTED] Using the GDAL tools, I've built a mosaic of terrain tiles that I'm stitching together using osgdem to create a terrain database. Each terrain tile uses a UTM mapping that is reprojected from a lat/long mapping. Unfortunately when I do the reprojection for each tile, the terrain tile gets slightly shifted so that when I stitch them all together using osgdem, I have discontinuities at each tile boundary in the finished terrain database. My question is, is there a way to avoid this nasty artifact using either GDAL or osgdem? Perhaps I need to resort to another tool to massage the data before handing it over to osgdem?

Re: [osg-users] osg and speedtree
Hi Jon, we have tried to integrate speedtree into osg. There are serveral ways to do it: 1. alternative: Just use the opengl example from speedtree and wrap it with a custom drawable. Using this solution there are many pros: * easy to integrate cons: * your are using the texture loading/management of speedtree * you loose the ability of multithreading/multicontext stuff of osg, because the speedtree example uses CG in a non-multicontext version 2. alternative: Create a osg wrapper for CG (as custom stateattributes) in osg and use the example to build the appropiate osg geometry. pros: * no need to touch the speedtree shader * useable in multicontext/multithreaded environment. cons: * Integrating CG into osg is a daunting task. However CG does not make any guaranties about the opengl state after it has been applied, so you can't use it with other stateattributes or in a hierarchy of statesets. So I wouldn't recommend using CG at all in OSG. 3. alternative: Like above you port all the geometry to osg as well as the CG shaders to GLSL. Porting the shaders to GLSL is easy. I haven't done anything with shaders before, but if you take a look at Mike Weiblen GLSL quickrefernce it should be really easy to port the CG shader. pros: * now is pure osg, you don't have any custom drawable or wrappers in it, EXCEPT: SpeedWind - Speedtree provides a class for creating wind. Just build a basic wrapper which gets called in the update cycle. The next thing you have to care about is how you organize your scenegraph (for LOD stuff). Thats were I am currently stuck with.

[osg-users] Offline rendering
Hello, some days ago I read some topics about offline rendering here but it was not important then. Now I need it and cant find it (Some topics were out of date using osg::Produer) Anyway, I have a seperated logic where I need to render some scene but never show it, since osgViewer renders the image to the screen I need something where I can add my scene, add my light, render it to an image, work on the raw pixel data (which is basically the osg:Image raw data) and discard it. The problem with frame buffer objects is, as far as I remember, is that they need to be linked to the output that is seen on screen which is in my case not guaranteed. Is there a possibility to achieve that? Thanks Sam ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] problem using overlay node
Hi all,
I am trying to overlay a shape file on a terrain using overlay node.
But the two textures are not blending, instead the overlay texture has
replaced the terrain texture. I am attaching the final rendered image
for you to ponder upon. I am using the code of osgsimulation example
which goes like this for my case.
// Get coordinate system node
osg::CoordinateSystemNode* csn =
dynamic_castosg::CoordinateSystemNode*(terrain.get());
// Set overlay technique
osgSim::OverlayNode::OverlayTechnique technique =
osgSim::OverlayNode::OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY;
// Create overlay node
osgSim::OverlayNode* overlayNode = new osgSim::OverlayNode(technique);
// Set blending parameters
overlayNode-getOrCreateStateSet()-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
overlayNode-getOrCreateStateSet()-setMode(GL_BLEND,
osg::StateAttribute::ON);
overlayNode-getOrCreateStateSet()-setTextureAttribute(1, new
osg::TexEnv(osg::TexEnv::BLEND));
overlayNode-setOverlaySubgraph(shapefile.get());
overlayNode-setOverlayTextureSizeHint(1024);
overlayNode-setOverlayTextureUnit(1);
// Set clear color
overlayNode-setOverlayClearColor(osg::Vec4(0.0, 0.0, 0.0, 0.0));
// insert the OverlayNode between the coordinate system node and its
children.
for(unsigned int i=0; icsn-getNumChildren(); ++i)
{
overlayNode-addChild( csn-getChild(i) );
}
csn-removeChildren(0, csn-getNumChildren());
csn-addChild(overlayNode);
// Set scene data
viewer.setSceneData(csn);

[osg-users] Picking and Using Selection
Hi all, I am working at the moment on an university project and need some advices concerning picking and using selections in osg. My job is to generate and render a height number of polygons (+/- 12) and I need to pick them. In an first instance I have used the LineSegmentIntersector approach which was proposed by osg. But this solution was to slow for a high amount of geometries. Opengl provides on the other hand the GL_SELECTION render mode for this purpose. Is there any possibility to integrate this solution into osg? And if, how?

Re: [osg-users] About viewer.addEventHandler(new PickHandler())?
Hi ???, First of all, a little mailing list etiquette: 1. could you please sign your posts, it's polite to let others know how to address you. 2. When asking a new question, you should start a new thread (start a new message and not reply to another message). Now, to your question. scene-setUpdateCallback(new RotateCallBack()); ... My question is when next mouse PUSH , scene-setUpdateCallback(new RotateCallBack()) call again and new a RotateCallBack object. But can last time RotateCallBack object is auto-delete? You think there may be a memory leak? Look at the code for osg::Node (header and cpp file). osg::Node::setUpdateCallback(NodeCallback* nc) does some checking, but in the end, does this: // set the app callback itself. _updateCallback = nc; and _updateCallback is declared thus: ref_ptrNodeCallback _updateCallback; So it's a ref_ptr. Reference pointers manage the reference count of the pointed objects, and if that count goes to 0, the object deletes itself. So when setUpdateCallback() assigns a new callback to _updateCallback, the old one's ref count decreases by 1, and the new one's ref count increases by 1. If the old one's ref count comes to 0, it will delete itself. See osg::Referenced and osg::ref_ptr for details. As a general tip, I find that generating the doxygen documentation for the OSG source tree with INLINE_SOURCES = YES helps a lot when learning about how OSG does things. It gives you a nice way to browse the doxygen, and then go down to the actual code directly, with cross-references everywhere.

[osg-users] Anomaly when intersecting a VPB terrain
Hi guys, I have encountered a small problem with intersections. I am using the IntersectionVisitor and the LineSegmentIntersector to clamp objects to a geocentric terrain built with VPB (VPB head w/ OSG 2.6). Most of the time it works. But when the intersector line segment is exactly coincident with a terrain tile boundary (at the highest LOD) at the skirt underneath it, the intersection test will sometimes return zero intersections. Not at every tile boundary, but definitely at some. I came to this conclusion be rendering my line segment and seeing it exactly coplanar with the skirt geometry between the tiles. I would appreciate any ideas or suggestions on how to track down this issue.

[osg-users] Coordinate system mapping from WTK to OSG...
Hi All, At the risk of appearing very dense, could I ask for a little help with a problem that I have been banging my head against a wall with for the the past week? The problem is that I have a position and orientation of an observer described by a position vector, and a vector of euler angles that represent the orientation of the observer. To complicate matters, the coordinate system in operation when this information was created was that of WorldToolKit (WTK) - in fact we were using WTK when creating this information. In this system positive Y is down, and positive Z is in towards the screen, with positive x traversing left to right. Now, I would like to represent the position and direction of view (orientation) in OSG's coordinate space. Now, as I understand it, a rotation of -90 degrees will take a point in OSG space, and represent it in WTK space - and the inverse doing the reverse. Cool. The issue I have is what should happen to the orientation vector. The euler angles were obtained from WTK's quaternion to euler function. I've looked at the order of multiplications that occur in WTK when creating the resultant rotation, yet I still can't seem to get the correct result. So, if anyone out there has experience of mapping from WTK to OSG, specifically in regards to what should happen to rotation angles, and quarternians, I would be most grateful - and perhaps my wall could then be repainted beige instead of red ;-( Many thanks for any help Neil. I am trying to bring this into OSG. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I use : light-setUpdateCallback(new lightMoveCallback()) Not sure what you're doing with your callback, but in OSG, lights are positioned using a LightSource node, so perhaps your callback changes are being overridden by that? The LightSource node is placed in the scenegraph where you want the light to be, usually under a Transform. Typically, to move the light, you can just add a UpdateCallback to the Transform to do what you want. I don't know why your callback isn't called, though.

[osg-users] Group::getNumChildren()
This method returns an unsigned int. It calls size() on the vector, which returns size_type. In our builds of software using OSG, we're getting warnings about a conversion of a 64 bit value to unsigned int. Has the OSG project had to change the type of common methods like this? Does it go well? I haven't had time to do any compiling of OSG for a long time (since we got 2.4.0 built and integrated). In this case, I'm adding a new file that gives this warning, and we've got structure in place to make it difficult to add files with warnings in compilation. I don't think it is likely to be a problem. One possibility is to cast it in the method. Is that what should be done? thanks andy ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] light Callback
Hi, Try adding your osg::Light to a StateSet, i.e. (pseudocode) group = osg::Group() lightsource = osg::LightSource() light = osg::Light() light.setLightNum(0) lightsource.setLight(light) group.addChild(lightsource) group.getOrCreateStateSet().setAttribute(light, osg::StateAttribute::ON) viewer.setSceneData(group) It seems StateAttribute callbacks are only called when the attribute is set on a StateSet. Setting the light as state attribute on lightsource does not seem to work, which is a bit surprising as a osg::LightSource is a Group and therefore also has a StateSet. Actually, I find the whole Light / LightSource (which is a Group) / Light set as a StateAttribute a bit confusing.

As far as I know, I've followed the instructions in the README - unpack the zip, use the Cmake gui, build with Xcode, install to /usr/ local So I come back to, I must have screwed something up, but I'm unclear what.

[osg-users] 回复： Re: About viewer.addEv entHandler(new PickHandler())?
Thanks Jean-Sébastien Guay
1. I already update my user info.
2. I have another question, when viewer.frame() which thread listening
windows message(example mouse clicked,keyboard down ,up etc) ,and when
i update my scene node in updatecallback,How threads guarantee sequence?
for example :
mouse PUSH
{
mynode-setUpdateCallback(new mycallback() );
}
mouse RELEASE
{
mynode-setUpdateCallback(new mycallback() );
}
and all threads execute sequence synchronize with above code?
Thanks.

Hi ???,
First of all, a little mailing list etiquette:
1. could you please sign your posts, it's polite to let others know how
to address you.
2. When asking a new question, you should start a new thread (start a
new message and not reply to another message).
Now, to your question.
scene-setUpdateCallback(new RotateCallBack());
My question is when next mouse PUSH ,
scene-setUpdateCallback(new RotateCallBack()) call again and
new a RotateCallBack object.
But can last time RotateCallBack object is auto-delete?
You think there may be a memory leak? Look at the code for osg::Node
(header and cpp file).
osg::Node::setUpdateCallback(NodeCallback* nc) does some checking, but
in the end, does this:
// set the app callback itself.
_updateCallback = nc;
and _updateCallback is declared thus:
ref_ptr _updateCallback;
So it's a ref_ptr. Reference pointers manage the reference count of the
pointed objects, and if that count goes to 0, the object deletes itself.
So when setUpdateCallback() assigns a new callback to _updateCallback,
the old one's ref count decreases by 1, and the new one's ref count
increases by 1. If the old one's ref count comes to 0, it will delete
itself.
See osg::Referenced and osg::ref_ptr for details.
As a general tip, I find that generating the doxygen documentation for
the OSG source tree with INLINE_SOURCES = YES helps a lot when learning
about how OSG does things. It gives you a nice way to browse the
doxygen, and then go down to the actual code directly, with
cross-references everywhere.
Hope this helps,
J-S

[osg-users] CG for Simulation BOF at Siggraph
Hello, Shameless Plug: SCS Simulation and Computer Graphics BOF Tuesday 12:30-1:30PM Room 507 Does not conflict with the OSG BOF. Note: SCS = Society for Computer Simulation International (www.scs.org http://www.scs.org/ ) There was an OpenScengraph paper published in the SCSC '08 conference sponsored by SCS. Also, a COIN paper (standards) in the SISO (Simulation Interoperability Standards Organization) conference. My paper (VRML) mentioned COIN and OSG. I'll give a very short synopsis of the CG and simulation events at SCSC '08 and pass out flyers for SCSC '09. I'll also talk about some OSG stuff from the National Association of Broadcasters meeting. BOF Organized late and so the agenda is completely open. The authors of the OSG paper were Johann Loewen and Kaies Chaouch from the Kniversity of Kassel (DE). [EMAIL PROTECTED], [EMAIL PROTECTED] Lastly, I will bring chocolate to the BOF. John F.

COLLADA and KHRONOS are Web3D technologies. Open Scengraph is sort of the Open Inventor functional clone that has a totally free license and is a Web3D technology [hope this assessment is reasonably correct]. Shameless Plug: Simulation and Computer Graphics is my BOF. You must attend Lots of other BOF's. However, these listed BOF's just about fill up anyone's Web3D day for the entire conference. Then there is the conference, exhibits, art gallery, eating, sleeping, partying. I do have a pocket universe with 29 hours per day for those that have to attend more BOF's. John F.
