D.1. Debugging Tools

Several tools exist to aid developers in debugging and tuning their applications. Developers can use these tools to capture sequences of OpenGL commands issued by an application, set breakpoints at OpenGL commands, and examine OpenGL state. Some also provide performance information.

At the time this book went to press, popular OpenGL debugging tools included Apple's OpenGL Profiler, Graphic Remedy's gDEBugger, GLIntercept, and SGI's ogldebug. Linux and Unix systems also feature glxinfo.glxinfo isn't a debugger but nonetheless is useful as a diagnostic tool.

Information on OpenGL tools is subject to change over time. To stay abreast of current tools, visit the OpenGL Web site regularly, or use an Internet search engine to search for "OpenGL debugger" or "OpenGL tools."
