Re: [osg-users] Getting world space normal
Well, not so much a requirement as OpenGL convention. GL defines a normal as a 3-component vector (there are only the glNormal3*() calls, unlike glVertex which has many sizes) And the GLSL builtins : gl_NormalMatrix is a mat3 and gl_Normal is a vec3.

Re: [osg-users] Counting visible vertex
osgOQ is no longer an extension -- OcclusionQueryNode is part of OSG v2.4. However, as currently implemented, it does not return to you a count of the number of visible vertices. OSG, like many rendering doesn't provide direct support to return the number of visible vertices. However, you should be able to use any general algorithms that exist to perform this task. To determine the pixel size of a bounding sphere, you can use the distance and radius along with the combined modelview and projection matrices. OcclusionQueryNode could probably be modified easily to return a count of the number of visible pixels of the bounding box, but it doesn't currently do this, as that was not a design goal. -Paul _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of a.lagnier Sent: Tuesday, May 27, 2008 10:28 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Counting visible vertex Hi all, I want to calculate number of no occlusing vertex.

[osg-users] threading trouble with slave cameras
Hi, I just tried to replace SceneView with osgViewer::Viewer to take advantage of threading. My scene has 3 views of the same scene with cameras set up like this: Viewer camera / | \ far_cam1far_cam2 far_cam3 | | | near_cam1 near_cam2 near_cam3 (POST_RENDER) (POST_RENDER)(POST_RENDER) \ | / scene The viewer camera is only used for clearing. The near and far cameras are used to render different depth ranges of my scene to prevent a lot of z-fighting; each pair of near/far cameras draws into the same viewport. With no threading, I use 1 core at 100%. With CullThreadPerCameraDrawThreadPerContext I use 1 core at 100% and another core at about 25%. There are still 2 cores that are nearly unused. The other threading modes do not appear to help. I tried to trace through the threading code in ViewerBase a little. In cameras (the vector of osg::Cameras) there is only 1 camera, but I expected to find 7. Is it impossible to have 7 cull threads in this situation, or am I just setting something up wrong? - Terry ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Openthreads problem on 64 bit windows system.
I'm having a problem with an existing application that runs well on a
32-bit windows XP (VS 2003) system, but does not seem to work when ran
on a 64-bit windows XP (VS 2003) system.
I narrowed down the problem to Openthreads, seems that my threaded while
loop never (or rarely) gets called. I was able to recreate the problem
with this simple program below. It runs two threads, both printing a
message to the screen. Only one message is displayed on a 64bit
machine. I turned on OSG notification to DEBUG, but no extra
information is displayed.
Has anyone else experience this problem? Am I doing something wrong?

Are you on a multimonitor NVIDIA system by any chance? If so, this is a known issue in the NVIDIA device driver. Not sure what the workaround was -- I think it had something to do with additional MakeCurrent calls. You should check the archives; this was discussed within the past month. You might try the current SVN head to see if it resolves this issue.

Re: [osg-users] can't remove all PrimitiveSet
Paul , thank you. Yes, the right way is : *geometry-removePrimitiveSet( 0 , geometry-getNumPrimitiveSets() );* The problem is caused by my another code. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
