Class TriangleCellType

Cell type for a regular hexagon with 6 sides. Supports both flat topped and flat sides orientations. Up/down triangles are given separate dirs and corners, so you can distinguish them without needing separate cell types. Thus this cell type is quite similar to HexCellType.

CellDirs are FSTriangleDir/FTTriangleDir, integers 0 to 5. CellCorners are FSTriangleCorner/FTDirableCorner, integers 0 to 5. The CellRotations are the numbers 0 to 5 for a CCW rotation of that many sides, plus numbers ~0 to ~5 for the reflections, where rotation ~0 has dir 0 as a fix point.

The canonical shape (for use with deformations) is a regular triangle with incircle diamater 1.0 in the XY centered at the origin, with normal pointing Z-forward.

GetCornerPosition(CellCorner)

Returns the position of a given corner in the canonical cell shape.
