| Constant | Value | Description |
| siInterpolatedVertexGeometricNormals |
0 |
Interpolated vertex normals, each vertex normal being the normalized sum of normalized cross products
of edge vector pairs bounding adjacent polygons.
|
| siInterpolatedAngleBasedVertexGeometricNormals |
1 |
Similar to method siInterpolatedVertexGeometricNormals, but weights the adjacent polygons' cross
products proportionally to the angles formed by neighbor polygons. Slower than
siInterpolatedVertexGeometricNormals but gives higher quality, particularly with polygon meshes
having many triangles.
|
| siInterpolatedNodeShadingNormals |
2 |
Interpolated node shading normals. A node shading normal is computed as the sum of the adjacent
polygons' normals. In addition, it takes into account polygon mesh's hard edges and auto-discontinuity angle.
|
| siInterpolatedAngleBasedNodeShadingNormals |
3 |
Similar to siInterpolatedShadingNormals, but weights the adjacent polygons' normals proportionally
to the angles formed by neighbor polygons. Slower than method siInterpolatedNodeShadingNormals but
gives higher quality, particularly with polygon meshes having many triangles.
