[osg-users] LineSegmentIntersector and line width

Hi, I'm using osgUtil::LinesegmentIntersector to pick objects from my scene. It works all fine except Geode containing line geometry (with LineWidth stateset). But, I want to pick somes thick lines, how can I do? Thanks in advance! Aude Créez votre adresse électronique [EMAIL PROTECTED]

Re: [osg-users] DataVariance

Hi Paul P. You will have to debug this on your own I'm afraid, this type of issue is not something one can resolve without seeing it first hand. The best I can do is recommend that look into the using DataVariance set to DYNAMIC on all StateSet and Drawable that you have in your scene. This is

Re: [osg-users] Texture coordinates question

Hi John, You'll need to duplicate your vertices to be able to have different tex coordinates as osg::Geometry only support per vertex bindings for tex coordinates. For performance it's a false economy to vertex indices or per primitive bindings as they drop the OSG down on to OpenGL slow paths.

Re: [osg-users] DataVariance

Hi, i have encountered some similiar problems with multithreading (and the datavariance stuff). One thing I have considered is changing the design of osg::Statesets and osg::StateAttribute to immutable classes. So once the stuff is created you can only change it by cloning it. At least for those

Re: [osg-users] StateSetSwitchNode suggestion.

Hi Robert, The most general approach is the best, and the performance differences will almost certainly be negligible between your suggest SwitchStateSetNode and my suggest Layer node with nodemask. Feel free to implement both and test them against each other w.r.t cull traversal time

Hi Viggo, Thanks for the explanation. I don't think your needs are particular different from most who are writing games/simulators with the OSG. While large scenes LOD's is crucial, and for massive scenes Paging is also crucial. The OSG supports both so should scale to larger scenes. The other

[osg-users] bug - resources aren't properly deallocated when a viewer is destroyed

Hi, I have a simple example that shows that if you run a viewer, tear it down and run it again, textures are missing. (winXP, 2.6.0). It appears that resources such as Textures and DisplayLists are leaking and corrupting runs. The attached example simply creates a viewer and loads the

Re: [osg-users] bug - resources aren't properly deallocated when a viewer is destroyed

Hi Brett, The Viewer does it best to deallocate and clean up all buffers on the scene graphs that it knows about, but your code is hidding the scene graph from it by removing them from the view's scene graph so these removed elements do go throw the OpenGL clean up process. If you really want to
