bool
isSilhouetteEdge(U32 edgeIndex)
Return true if the given edge is a silhouette edge with respect to the view direction.
Detailed Description
Silhouette extraction routines for orthographic projections.
Per-Extraction Data
F32 * mFaceDotProducts
Precomputed dot products between view direction and plane normals in the polyhedron.
U32 mWaterMark
Frame allocator water mark.
Public Functions
SilhouetteExtractorBaseOrtho(const Polyhedron & polyhedron)
begin(const Point3F & viewDirOS)
Initialize the extractor.
end()
Finish extraction.
isSilhouetteEdge(U32 edgeIndex)
Return true if the given edge is a silhouette edge with respect to the view direction.
Parameters:
| edgeIndex | Index of edge to test. |
True if the given edge is a silhouette in the projection along the view direction.
note:This method depends on inward-facing normals!
