This project uses the pen and a bit of math to turn a 3d point where Z is "how far away" into a 2d point and uses this to draw a 3D cube. Now imagine you are using the sliders to move a camera looking at the cube: X is left and right. Y is up and down. Z is depth or distance.. CHALLENGE FOR THE WEEK: - Remix and make your own shapes - Different height and width cuboids Pyramid (easy-ish) Toblerone (bit trickier) A basic house (ultimate ninja skills, but doable) Finally - Make it so that the keyboard controls move the camera variables and take away the sliders - now you are in a 3d game!
