[out] endPointIndex Tetrahedron index of the second point.

◆  GetPointIndexOfPoint()

Int32 GetPointIndexOfPoint ( Int32   pointIn ) const

Gets the point indices between 0 and 3 of one input point. If the index cannot be found it will not be written.

参数
[in] pointIn Point index to get the index of.
返回
The points Tetrahedron index.

◆  GetFaceWithPoints()

Int32 GetFaceWithPoints ( Int32   point1 ,
Int32   point2 ,
