Mini-HOWTO : visualizing 3D data using Octave, VRML and FreeWRL1

Abstract:

This document shows how to visualize sets of 3D points, 3D curves, surfaces etc using the numerical language Octave, in conjunction with the VRML browser FreeWRL. The basic functionalities and principles are presented here with examples, while the detailed synopsis can be obtained from the online help system.
