The FrustumCulling class traverses the filtered mesh (see IMeshFilters.FilterIn), performs a visibility tests for each mesh sector with the configured frustum (see Frustum) and culls away all sectors that are outside of it (see MeshTree.SectorCull).
Each visited mesh sector is tested against the frustum. If it lies outside the frustum, it will be culled away (see MeshTree.SectorCull).
The following vertex data semantics are used by this class:
Creates a new instance of FrustumCulling.
The mesh tree input filter to use for querying sector culling and marks.
The default value is
null (i.e. all mesh sectors are visited).
