Parameters
| Name | Description |
|---|---|
| NumIndices | iterate from 0...NumIndices and call TriangleGenFunc() for each value |
| TriangleGenFunc | called to fetch the triangles for an index, callee filles TrianglesOut array (reset before each call) |
| TrianglesPerIndexHint | if > 0, will reserve space for NumIndices*TrianglesPerIndexHint new triangles |
