4D Draw 对比 4D Toys 的使用情况和统计数据

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.

4D Toys

"I am not sure that I've ever seen a more compelling 'show-don't-tell' educational tool than 4D Toys." –Ars Technica What if you received a box filled with mysterious toys from a fourth spatial dimension? • Playfully explore and marvel at beautiful shapes powered by a groundbreaking 4D+time physics system. • Poke, throw, roll and watch as they disappear into a dimension you can't see. • Get an intuitive feel for how four-dimensional objects behave: • Become a child of the fourth dimension. In this case the 4D is not time but a 4th dimension of space that works just like the first three dimensions we are familiar with. If you count time these toys are 5D. It turns out that the rules of how objects bounce, slide and roll around can be generalized to higher dimensions, and this unique toy lets you experience what that would look like. Features: • Over 130 beautiful interactive scenes to play with, with more to be added in updates. • Groundbreaking 4D+Time Physics Engine that uses new mathematics created for this project. • Multi-touch & Accelerometer support for rich interactivity. • 2D/3D "Flatland" Interactive 10 Page Book/Explanation that teaches by analogy about a fourth spatial dimension. • Special buttons: Anti-Gravity, Wireframe Projection, 4D Accelerometer and ability to export meshes for 3D printing. Some things to do: • Manage to fit the hypercube into the hyperhole! • Use the 4D shapes as fancy, perfectly symmetric, fair dice that have 5, 8, 16, 24, or even 120 and 600 sides! • Unbind Rings using the fourth dimension! • Make a stack of 4D hypercubes and smash it! • Set up an interesting path for a few 4D dominoes! • Make levers that throw hypercubes into the fourth dimension! • Use multitouch to "squeeze" out objects into the fourth dimension! • Play in a 4D ball pit! • See Tesseracts (i.e. 4D hypercubes) slide down slopes! • etc...!
