4D Draw
iOS Universel / Education
4D Draw is a simple vector-graphics app that lets you draw 4‑dimensional 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.
4D Draw is intended for geometry students who want to learn to visualize 4‑dimensional 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.
Quoi de neuf dans la dernière version ?
– 4D Draw runs on iOS, iPadOS and now on macOS too. The file format is the same, so you can view and edit your drawings on all three platforms interchangeably.
– Press and hold a drawing's icon in the 4D Draw file browser on iOS to share its vector-graphic source code by Mail, Messages, AirDrop, or Save to Files. On macOS you can send the .draw4d file in those same ways, by selecting it within the relevant apps.
– Share PNG images of your drawings in all ways imaginable: Mail, Messages, AirDrop, Save to Files, Copy, and others.
– Updated for iOS 17+
– Note: iOS's document picker sometimes leaves a spinning wait cursor visible over the icon of a recently saved drawing. It's annoying but harmless — your drawing really has been saved and you can ignore that wait cursor which will go away when you re-open that drawing or another one.
