| 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. |
