static void ComputePerTriangleOcclusion

Remarks
Compute per-triangle visibility array for a triangle mesh
Parameters
| Name | Description |
|---|---|
| OutTriOccluded | For each valid triangle ID, OutTriOccluded[ID] will be true if that triangle is hidden, false if it is visible |
| bPerPolyGroup | If true, visiblity will be determined on a per group basis: If any triangle in a group is visible, the whole group will be marked as not-occluded |
| SamplingParameters | Parameters controlling how exterior visiblity is tested |
| SkipTris | True for triangles do not need visibility testing (will be marked as not occluded). If empty, no triangles will be skipped. |
