You might want to ask these Opengl questions over at the probably more appropriate forums at www.opengl.org

Shaders tools like FX Composer and the most powerful Shader Debugger gives DX programmers most flexible and ease. Why not OpenGL? I noticed Orge3D should be a choice if you want crossing platform support and NVIDIA CG support. Should my virtual surgery project to use Orge3D? But, seeing the screenshots of Orge3D, it is mostly used in Game, I can see no medical projects using Orge3D. It just like a game engine. VTK is mostly used in this situation, but I can't sure if it is powerful in scene management and easy to program. Hard to decide..... My current choice is OSG, but what is the future?

I must find a way to see the rendering detail in order to debug my program. If there's really no simple way to do this, it will be a pity. I think it's a real shame that NVPerfHUD is DirectX only. It looks like a really good tool for this kind of work. http://developer.nvidia.com/object/nvperfhud_home.html http://www.youtube.com/watch?v=UdDfvq0cL04 (really cool!) http://www.youtube.com/watch?v=S3_fP3-psJY Maybe this community could put pressure on NVIDIA to port it to OpenGL too?
