The new gDEBugger V5.1 adds the ability to view Vertex Buffer Objects (VBOs) data. The Textures and Buffers viewer Data View tab displays the selected VBO's data in a spreadsheet. The user can select the displayed data format, offset and stride. gDEBugger, an OpenGL and OpenGL ES debugger and profiler, traces application activity on top of the OpenGL API, lets programmers see what is happening within the graphic system implementation to find bugs and optimize OpenGL application performance. gDEBugger runs on Windows, Mac OS X and Linux operating systems.
