				<div class="class-description"><p>This class can be used to modify a geometry by simplifying it. A typical use
case for such a modifier is automatic LOD generation.</p>
<p>The implementation is based on <a href="https://web.archive.org/web/20230610044040/http://www.melax.com/polychop/">Progressive Mesh type Polygon Reduction Algorithm</a>
by Stan Melax in 1998.</p></div>

geometry = modifier.modify( geometry );
