Remarks
Select the occluded triangles, considering the given occluder AABB trees (which may represent more geometry than a single mesh) See simpler invocations below for the single instance case or the case where you'd like the spatial data structures built for you Selection will be stored in the RemovedT array, but no triangles will be removed. true on success
Parameters
| Name | Description |
|---|---|
| MeshLocalToOccluderSpaces | Transforms to take instances of the local mesh into the space of the occluders |
| Spatials | AABB trees for all occluders |
| FastWindingTrees | Precomputed fast winding trees for occluders |
| SpatialTransforms | Transforms AABB/winding tree to shared occluder space (if empty, Identity is used) |
| bTestOccludedByAny | If true, a triangle is occluded if it is fully occluded by any occluder. Otherwise, we test if it's occluded by the combination of all occluders. |
