The high speed in the project is achieved by caching a 360 image of the rays. Then when the player is not moving, it's simply a case of running 3D projection and rotation on all the rays. When the player is moving, only 80 degrees are of rays are casted and the accuracy and resolution is lowered heavily. Everything by me! #3D #Raycaster #Pen #Editor
