Chapter 598: SimplifyModifier

Core Idea

This class can be used to modify a geometry by simplifying it. A typical use case for such a modifier is automatic LOD generation.

The implementation is based on Progressive Mesh type Polygon Reduction Algorithm by Stan Melax in 1998.

Code Examples

const modifier = new SimplifyModifier();
geometry = modifier.modify( geometry );

• What it demonstrates: Typical usage of SimplifyModifier.
