Use the arrow keys to rotate the shape: right/left rotate the shape around the y-axis and up/down rotate the shape around the x-axis. Use the WASD keys to move the shape. Use Q and E to enlarge/shrink the shape. Press R to reset the shape's position, rotation, and size. Press space to toggle on/off the debug view. Toggling the "Points" variable on/off will show/hide vertex points. Press keys 1-3 to choose the shape to render: 1 is a cube, 2 is a pyramid, and 3 is an octahedron.
Thanks for the original idea from @TiberiumFusion
