# Great Software For 3D Visualization Of Geometry

This page lists some fun geometry software i've used. Usually they are visualization software for non-Euclidean geometry or higher-dimensional geometry.

## Curved Space

Curved Space Jeff Weeks wrote a wondrous program that lets you fly thru various “warped” geometric spaces (3-manifolds). Source code and tutorial are included for programers. Home page: http://www.geometrygames.org/CurvedSpaces/index.html. OSX Win

Jeff Weeks wrote a excellent book to accompany the program. 〈The Shape of Space〉 amazon.

## KriviznaPlus And KriDva

KriviznaPlus and KriDva by Viktor Massalogin. KriviznaPlus draws the Stereographic Projection from 3D to plane. KriDva draws the stereographic projection of S^3 sphere (x^2+y^2+z^2+z^2==r^2) to the 3D space. These programs are extremely fun and beautiful. I hope the author adds more explanations on the math. As of 2004, he added another version CPace. Home page: http://www.hot.ee/bntren/Program.html. Win

## stereop

stereop by mathematician John M Sullivan. This applet does Stereographic Projection of regular polyhedrons. User can choose any of cube, tetrahedron, octahedron, dodecahedron, icosahedron, and they are centrally projected onto a sphere. This sphere, is then stereo-graphically projected onto a plane. User can rotate the polyhedron, and see its image on the plane change accordingly. Home page: http://torus.math.uiuc.edu/jms/java/stereop/. Java

## SeifertView

SeifertView by Jack van Wijk, is a software to visualize Knot-rim Surfaces (aka Seifert surface). A knot-rim surface is a surface such that its edge is a knot or link. Home page: http://www.win.tue.nl/~vanwijk/seifertview/ Win
