TypeMemberDescription
floatHardEdgeAngleSet HardEdgeAngle in degrees. If the angle between two triangles are above this value, the normals will not be smooth over the edge between those two triangles.
uint8ReorthogonalizeTangentSpaceIf set, the tangentspaces already existing in the scene will be readjusted so that the tangent and binormal are both orthogonal to the normal. Will be needed since most of the time the normals are changed in the reduction process.
uint8RepairInvalidNormalsIf set, normals that are invalid will be replaced. All others are left intact. Bad normals are those that are either zero length, or simply points away from the surface.
uint8ReplaceNormalsIf set, it will generate new normals for the Geometry, and if not set, it will keep the normals from the original normal set (or not add normals at all if none were present). Please note that if the original geometry contains normals, the normal repairer will replace invalid normals even if ReplaceNormals is set to false.
uint8ReplaceTangentsIf set, it will generate new tangents and bitangents for the Geometry, and if not set, it will keep the new tangents and bitangents from the original normal set (or not add tangents and bitangents at all if none were present).
uint8ScaleByAngleIf set, the influence of a triangle normal upon the vertex normals is scaled by the angle of the corner at the vertex.
uint8ScaleByAreaIf set, the influence of a triangle normal upon the vertex normals is scaled by the area of the triangle.
uint8SnapNormalsToFlatSurfacesIf set, perfectly flat shaded surfaces will be created, where possible. Normals adjacent to perfectly geometrically flat surfaces will be recalculated to have the same direction as for those of the adjacent flat surface.
