Hey, here's the article Paul is speaking about#058; http://forum.openscenegraph.org/viewtopic.php?t=2190 I'm one of the guys in that discussion. I asked how to modify a line dynamically. Since you're using viewer.run(), that makes life difficult. I believe you'll need to use the viewer frame

[osg-users] Using vec3d for CullStack eye point

Hey all, First off, this is NOT another can we change all vec3 to vec3d thread. My question is more specific. :) In osg::CullStack, the EyePointStack is a Vec3 stack, therefore a Vec3f stack. However, the stack itself is built up using elements from a osg::Matrix, which could be a

Re: [osg-users] Dynamic Modification..

HI Allen, viewer.frame() calls viewer.updateTraversal(), and viewer.run() calls viewer.frame() so your suggest frame loop would only call updateTraversal() twice. Instead to expand viewer.run() - a frame loop with it's component parts you do (please look at the implementation itself to confirm

[osg-users] Newbie question regarding deprecated methods

Hi, I'm trying to learn to use OSG using the tutorials on the wiki, starting with this: http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials/BasicGeometry, during the coding, I learned that setColorIndices has been deprecated, unfortunately I'm having difficulties figuring out

Re: [osg-users] Newbie question regarding deprecated methods

setColorIndices, setVertexIndices, etc., allow you to have a different set of indices for each array, so that (for example) the vertex with index 89 could be drawn with the color with index 42. Sounds really flexible, but unfortunately there's no way to do this in OpenGL 1.x/2.x other than the

Re: [osg-users] Using vec3d for CullStack eye point

I would think that anyone who intentionally requests double precision matrices is doing so out of need, and would probably be willing to accept the inevitable performance hit. Is there anything I should do to get this change started? I'm sure you are busy with other issues so I can try

[osg-users] How to recreate GraphicsContext?

Hi, I am working to make a osg scene editor with MFC. I just followed the example of osgViewerMFC and create a GraphicsContext for every MFC document. For the 1st document everything runs smoothly, but when I tried to create another GraphicsContext, the program throws a exception. So, how
