GPU Rendering - what really happens

[solidworkattack]

Hello,

I'm currently planning my bachelor thesis. I thought about a lot of things but the idea of visualising the process of rendering always comes back into my mind.
I learned a lot about rays and things like that. I think I kind understood the basics of how images are getting created - but I'm really curious about the things that happen in the graphicscard while gpu rendering. I mean what do the single cuda cores do - what kind of information do they collect and how are things getting processed until the become a final image? Does every single core shoot one ray into the scene or how are things working? As I said I want to visualise it, I think it's funny that people just hit the render button and don't even know what complex stuff is going on in their workstation.

Can you link me any video / article reference for this topic or do you know stuff about it?

I'm really thankful for any help!
Have a nice evening

Hi,
you can check CUDA, OPENCL keywords. Also check nvidia, amd(ati) and opengl webpages. It will show many guides. Best.
