2D Raycaster Engine Implemented Using Compute Shaders

2D Raycaster Engine

Traditional 2D raycaster engines run on CPU so they have a bottleneck on loading screen texture from CPU to GPU for each frame.

This raycaster engine is implemented using compute shaders so it does not have this bottleneck as it runs on GPU.

Textures belong to Wolfenstein 3D.

Raycaster codes are taken from Lode Vandevenne's tutorials and adopted.
