Module VRML2



Definitions of simple 3D graphics objects and VRML scenes containing them

The objects are appropriate for data visualization, not for virtual reality modelling. Scenes can be written to VRML files or visualized immediately using a VRML browser, whose name is taken from the environment variable VRML2VIEWER (under Unix).

This module uses the VRML 2.0 definition, also known as VRML97. For the original VRML 1, use the module VRML, which uses exactly the same interface.

Example:
 >>> from Scientific.Visualization.VRML import *    
 >>> scene = Scene([])
 >>> scale = ColorScale(10.)
 >>> for x in range(11):
 >>>     color = scale(x)
 >>>     scene.addObject(Cube(Vector(x, 0., 0.), 0.2,
 >>>                          material=Material(diffuse_color = color)))
 >>> scene.view()
