GLIntercept

GLIntercept is a debugging tool designed to capture and create logs with all OpenGL calls on 32-bit and 64-bit Windows computers. This function call interceptor works for any OpenGL-compatible application.

Worth noting is that you must download the architecture type supported by the program you want to debug, which doesn't necessarily have to equal your operating system's.

The installation operation is speedy and requires minimal user intervention. Afterward, it's necessary to copy the opengl32.dll library and gliConfig.ini configuration file (from the installed directory) to the .exe folder of the program you're intending to intercept for OpenGL calls.

In the following step, you can examine the gliConfig.ini file and make modifications if you're not satisfied with the default configuration. For example, it's possible to disable function call logging, flush the logger after each OpenGL call on text files (useful for troubleshooting crashes), as well as set the name and path for storing the logged files (otherwise, they are saved in the same location as opengl32.dll).

There are several predefined configuration files available in the downloaded package, such as basic text logging with image list dumping (default gliConfig.ini), a demo showing how to use the OpenGL version override plugin (gliConfig_ExtOverride.ini), and the author's preferred development settings (gliConfig_DebugContext.ini).
