gDEBugger is an OpenGL API debugger that lets programmers trace application activity on top of the OpenGL API to see what is happening within the graphic system implementation. The new v1.1 includes “Interactive Mode” and “Raster Mode” toolbars which enable programmers to watch objects as they are being rendered in shaded, point or wire-frame mode and break the program execution where they would like to debug. It also now supports applications that load OpenGL32.dll dynamically and applications that use OpenGL through an ActiveX control / OCX / COM object.
