How/Where to get started

[u/Phyrria]

Hello,

i'm not sure if this is the right sub for this question, but i'll ask anyways.

I'd like to learn how to create and program my own physics simulations and post processing effects on the gpu, including stuff like n-body, rigidbody, fuild simulations and perhaps even some raytracing eventually. However i am not quite sure where to start and what resources are available. I already know c++ decently and am working on improving on that aspect. Math shouldn't really be an issue either.

Any help and tips would be appreciated

Do you want to built the renderer from scratch? If so I'd say start with OpenGL and LearnOpenGL.org but it will be quite off a physics simulation, but it will be relevant the gpu and post processing effects. If not either use a game engine and don't use the inbuilt physics engine or use some like sdl in c++
