HOW IS THIS PROPOSED ALREADY- Uses https://scratch.mit.edu/projects/1193044173/ as an engine. WASDQERF to move (R and F for ana/kata, QE are up/down), IJKL to rotate, P + IJKL to rotate too (but 4d roll). If you’re wondering what happened to two of the directions, basically IDK how to account for stuff fully like roll, as you need to roll the other rotations and the rolls. No ZW sorting included. This is basically 4d blocks (search it up) but point clouds and less features The scene is a magenta 3-sphere on a white hyperplane. with a star very, very far up. https://turbowarp.org/1193094509?hqpen&offscreen for better graphics and performance Since this has a built-in uvts parametric hypervolume generation system (ex. the tesseract is uvts with an inequality), you can use this for 4d parametric volumes. This uses transparency for pen sizes less than 1. This is NOT The first project that does this: https://scratch.mit.edu/projects/863126613/ is an implementation similar to this.
