Goals of VOGL

[computerquip]

What are the goals of VOGL compared to alternatives? I think this should be clearly stated as it may help motivate some people to participate in contribution (including myself ;)).

Debugging, performance analysis, and driver bug / performance regressions. Primary goal is single frame debugging on Linux(first)/Windows/Mac - this would have helped our game porting efforts immensely and we think it needs to addressed as OpenGL gains more traction.

We would also like to add a mode where the last 10-15 seconds (or so) of the application is recorded to an in-memory round robin buffer. When the user sees a glitch they can hit a hotkey and save that to disk. Making this simple by getting it into the distros and Steam would be fantastic.

There are some great existing tools which do full stream capturing and Valve did put resources for adding single frame / trimming there, but it proved to be extremely difficult. There are also vendor specific tools, but we've generally found that working on other GPUs isn't a priority for them.
