= OpenGL Debugging with Bugle =

Some OpenGL bugs can give totally useless backtraces in GDB. (crash inside the GL driver).

Using bugle source - http://www.opengl.org/sdk/tools/BuGLe/

Copy doc/examples/filters into ~/.bugle/filters

Then instead of crashing it gives a useful message as to whats going wrong, like this... [NOTICE] checks.error: illegal normal array caught in glDrawArrays (unreadable memory); call will be ignored.

there are other options for debugging like showfps, trace, wireframe ... see ~/.bugle/filters for options.

With the "crash" filter I managed to get a valid backtrace from gdb too.

Thought It might be useful for people looking into VBO bugs for the first time.
