Normal Visualizer with Geometry Shaders
A beta release of GLIntercept 1.0 is now out at:http://glintercept.googlecode.com/files/GLIntercept1_0Beta00.exeA few things to note:- This is more a maintainable release - new function entry points and some minor bug fixes.- OpenGL3.0 + pure core profiles do not work correctly (will be fixed)- New resource types like array textures, geometry shaders etc are not currently logged.- No x64 bit program support.- Nvidia's multi threadded driver seems to issue an internal wglGetPixelFormat call on the first glGetError() after SwapBuffers. This internal call occurs on a different thread that does not have the main OpenGL conext - so it results in the OpenGL error:"GL ERROR - Function wglGetPixelFormat generated error GL_INVALID_OPERATION"for the first 23 times swap buffers is called.To fix, disable the multi-threadded driver from the Nvidia control panel:"Manage 3D settings -> Threadded Optimization -> Off"or you can enable the GLIntercept option "ThreadChecking = True" which will report the extra wglGetPixelFormat call occuring on a different thread. (as well as some other wglDescribePixelFormat calls made by the driver)I will probably do a few more betas before the final, so hopefully a few of the above features/fixes will make it in.As there are so many other OpenGL loggers on Windows these days I will probably not do too many more updates. (and OpenGL is a hard API to write a debugger for)Let me know of any bugs you encounter.
