Detailed Description

The CLUcone struct defines a cone. Cones are often used for visibility determination and in level-of-detail methods. Cones can be used to describe a gross frustum or a range of normals. This struct cannot be passed directly to OpenGL. Rather, it is used at the application level for application specific features or optimisations. For example, adjacent vertices on a mesh can be merged if the cone formed by their normals has a small angle.

Example
