debugging jogl+shaders

Hi guys,

I've been using jogl for quite some time now and learning cg with the experimental java bindings to cg. I would like to know if anyone has used any debugging tool for opengl and/or cg shaders. I would like to see a tool that could show me the opengl states for a given frame. Something like parallel nsights? I've heard of gdebugger but havent tried it yet. Can anyone comment on what tools they have used and ease of use. I have not used any gl debugging utility so far.. so this is new to me. I am on windows 7 64 bit using eclipse.

thanks

We have a thread about this in this forum already, AFAIK.

However, I used GLES trace/debug tools on mobile devices so far:

- IMG's POWERVR PVRTrace
<http://www.imgtec.com/powervr/insider/pvrtrace.asp>

- NV PerfHud for GLES
<http://jausoft.com/blog/2011/10/04/bug-hunting-on-android/>

both native library 'hooks'/wrapper worked flawless attached to Android/ARM
and Linux/ARM (POWERVR only).

I have not tried gdebugger yet.

Would be nice to have some vendor supported tool for desktop, indeed.

Thanks for your reply sven. Unfortunately i am not using ES. I see that nvidia perfhud for desktop is only for directX. I wish there was a blog or some resource where people might have this for desktop..
