writes "OpenGL debugging has always lagged behind DirectX, mainly because of the excellent DX graphics debugging tools shipping with Visual Studio and GL being left with APITrace. Valve's Linux initiatives are making game companies to think about OpenGL, and the video game company wants to bring a good open source OpenGL debugger to improve the ecosystem. Two major driver vendors have already expressed interest in helping them out. Valve has been developing VOGL mostly on Ubuntu-based distributions under Qt Creator. The software is expected to eventually support all OpenGL versions. Many more details on Valve's VOGL OpenGL debugger can be found via a blog post by Valve's Rich Geldreich."
