GET MARCHING: How I Used Compute Shaders to Make a Never Ending Ocean Environment

Sebastian's video: https://youtu.be/M3iI2l0ltbE GitHub repository: https://github.com/luizppa/game-dev-techniques#-marching-cubes The script for the camera controls in the video was also made by me, I expect to upload them to the asset store at some point, but for now, check them out on GitHub: https://github.com/luizppa/third-person-camera ------------------------------------------------------------------------------------ Disclaimers Multi core processors: in the video I mention that one CPU can only run one instruction at a time, while this is technically correct, it may oversimplify how processors work.
