I found the problem, is the data type of the mat that I was saving the image. Sorry for the post

this is the image: imageshack.us/a/img267/2125/depthmap.png

Have fun with interreflections. ;)

Thanks for your quick and detailed reply, i will take a look at shader image load/store and opencl you mentioned My major concern is portability and...

The thing is, ouputting messages is costly as hell. :) And being able to have the GL report stuff on its own without querying with glGetError() is...

Well, shader image load/store lets you read from and write to arbitrary positions of an image - however, you'll need not only GL4 capable hardware,...

hey, thanks for sharing your code. i've already implemented SSR at this moment. it has some problems. but the one that bugs me the most is because of...

Nope! Just said that blocking message output does not necessarily mean not collecting information. Of course it is highly appreciable to prevent...

it's not a question, stop spamming your site.

what do i do to get labels along with the contour lines? can you share ur algorithm for more reference? Thanks

I threw GLUT in the trash and switched to GLFW instead, everything works now! :) Followed the tutorial at: www.open.gl

So what you're saying is that the ARB is stupid. All OpenGL implementations that don't expose ARB_debug_output in non-debug builds are just being...

I didn't want to offend, of course. Surely it's worth knowing what you're dealing with. Since enabling debugging capabilities has to be a run-time...

I do. In fact, I guess most of the additional debugging code is active in both debug and non-debug profiles, and it does not affect performance (at...
