Hi I just want to mention that my sample codes for implementing stereoscopy in OpenGL applications are still availabe, but on new adress: http://www.gali-3d.com/archive/articles/StereoOpenGL/StereoscopicOpenGLTutorial.php |

Hi Michal. In an OpenGL stereo programme, how do we know if any particular function is hardware-accelerated (i.e. done by the graphics card rather than the DLL software code) ? David |

David: You never know this. Graphic card manufactures do not give precise information about what function is done in HW and which one is done in SW. In adition one command coud be executed pertialy in HW and partialy by CPU in software as well. On nVidia graphci card a whole subset of OpenGL functions coled "Imagin Subset" was done in softwar for a long time. One key function - color matrix multiplication esential for anaglyph creation or for YUV->RGBA transformation was (and maybe still is) done in software. I know this becouse I had done speed comaprion with Wildcat . |
