<!-- ==================== MODULE DESCRIPTION ==================== -->
<h1 class="epydoc">Module VRML2</h1><p class="nomargin-top"></p>
<p>Definitions of simple 3D graphics objects and VRML scenes containing
them</p>
<p>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).</p>
<p>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.</p>
<p>Example:</p>
<pre class="literalblock">
>>> 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()
</pre>
