what exactly cuda does for opengl applications?

I guess some portion of an opengl application used to run on CPU, and now through cuda people can run it on GPU, and accelerate those portions (portion of an opengl application or pipeline) .

Can someone explain me what exactly cuda does for opengl ? I mean exactly what operations are offloaded to GPU for processing by cuda?

CUDA is a totally separate API than OpenGL; you can use them at the same time but CUDA isn't necessary to get GPU acceleration of rendering. In OpenGL you use shaders, which are conceptually somewhat similar to CUDA kernels, to achieve hardware acceleration of many tasks in OpenGL.

CUDA does allow interoperability with OpenGL (and Direct3D) but it is by no means necessary; you'd usually only want to do that if you both want to do scientific computing AND rendering in the same application. That's becoming even less necessary though, now with compute shaders available in both GL and D3D
