- 3D Cube A test project for a 3D game I am working on. Feel free to use it as an engine in you own games. No credit needed. This project includes line drawing, cube drawing, wasdqe movement and arrow key looking but sadly no collisions yet. This does mean that if you walk into the cube you will create a parallax. Do enjoy the project though, I hope to make an updated version with collisions soon. Have fun.
