Public Functions
SilhouetteExtractorBasePerspective(const Polyhedron & polyhedron)
begin(const MatrixF & camView)
Initialize extraction.
Parameters:
| objectView | View->object matrix. |
end()
End extraction.
isSilhouetteEdge(U32 edgeIndex)
Return true if the given edge is a silhouette edge with respect to the current perspective transform.
Parameters:
| edgeIndex | Index of edge to test. |
True if the given edge is a silhouette when looked at from the given view position.
note:This method depends on inward-facing normals!
