Detailed Description

SLAccelStruct is an abstract base class for acceleration structures.

The SLAccelStruct class serves as common class for the SLUniformGrid, SLCompactGrid and the SLKDTree class. All derived acceleration structures must be able to build, draw, intersect with a ray and update statistics. All structures work on meshes.
