<h2 class="description">Description</h2>
<p>
Material information, usable for all VRML/X3D versions.

<p>VRML 1.0 and VRML/X3D &gt;= 2.0 materials work a little differently: VRML 1.0 has arrays of values, e.g. an array of diffuse color, while VRML/X3D &gt;= 2.0 is really a single material, e.g. one diffuse color. This class is designed to hide these differences as much as possible: it provides a simple common interface for getting material properties.

<p>Note that it doesn't try to abstract all material properties &mdash; there are some features that are simply fundamentally different in how VRML 1.0 and &gt;= 2.0 materials should be treated, and they cannot be abstracted under a common interface here.</p>
