APITrace makes it easy to record and re-trace various graphics API command streams, inspect states upon any call, view frame-buffers and textures, view the call data, further manipulate the data, profile the performance, and carry out various other tasks. APITrace has been covered several times on Phoronix so if this is your first time hearing about it see our earlier articles and visit apitrace.github.io.
While APITrace has made many improvements and is arguably the best open-source OpenGL tracer/debugger, there's still more work to be done to bring it up to the proprietary competition and what's offered on Windows. As covered last month on Phoronix, Linux still needs better OpenGL debugging support.
The purpose of today's article is to give APITrace another shout-out and to note some recent additions. Committed now is support for grouping of OpenGL calls for grouping of related GL calls. Some other work includes better tracing of GLX context attributes, expanded support for dumping of object labels, additional support in trace for GL_KHR_debug/GL_ARB_debug_output, Direct3D retracing improvements, a new surface viewer for the GUI, and much more. APITrace continues to see new commits almost daily.
