OpenGL call interceptor/logger




GLIntercept is a OpenGL 1.0-2.1 function call interceptor. You can use GLIntercept for various tasks like saving and tracking shaders, textures and many more.

Select the version of GLIntercept right for the application being debugged (x86 or x64) - Note you select the version of GLIntercept based on if the application is x86 or x64 (64bit) - not if the operating system is 64 bit.

Then after installation, simply copy the opengl32.dll and a gliConfig.ini file from the install directory to the executable folder of the application you want to intercept OpenGL calls.

Then edit the gliConfig.ini file, enable the options required and then run the application.
How it worksGLIntercept works by overriding the call to wglGetProcAddress, wrapping the real function pointer in some assembly and then returning it to the application being debugged.

This means that when new OpenGL extensions/versions are released, GLIntercept will automatically log the new functions.

However, while all function names are automatically logged, function parameters need to be specified. These are supplied via text files in a "C" style syntax that can be updated as needed.
eg. void glClearColor( GLclampf red, GLclampf green, GLclampf blue, GLclampf alpha );
