This is basically a cube that spins. How original.
Forum: https://scratch.mit.edu/discuss/topic/337855/ How to remix and make your own 3D model: Do not change any of the scripts except for the "draw shape" block definition and the script with "add point" blocks. To add your own points, modify the starting script and replace the points with your own. x and y are horizontal and vertical, z goes towards the camera for positive and away from it for negative (the camera is at -7). To actually render the shape, use the "draw shape" block. Use the "go to point # ()" block to find points; it goes to the point that was the nth to be added. Do not use the "go to x: () y: () z: ()" block, it does not rotate with the rotations. The rotation does not use a proper rotation system, it just modifies the locations of the points to rotate in the desired way. This results in tiny precision errors that are too small to notice, so you do not need to worry about that. Also, do not make points that may go behind the camera, they display weirdly.
