4D Draw for iOS

4DDraw is a simple vector-graphics app that lets you draw 4dimensional figures. It represents each point's first three coordinates in the usual way, while using color to represent the fourth coordinate. A built-in Help menu includes a How to draw page for an easy start, followed by a page of 4D construction ideas to set you on your way towards visualizing 4-dimensional space.4DDraw is intended for geometry students who want to learn to visualize 4dimensional space. People looking for a more recreational introduction to 4D should begin with 4D Maze instead. People looking for an even more recreational introduction to modern concepts of space and symmetry may enjoy the Torus Games or KaleidoPaint.
