generateNormals()
Usage
member(whichCastmember).modelResource(whichModelResource).
generateNormals(style)
Description
3D model resource command; calculates the
#mesh
If the parameter is set to
style
belongs. Furthermore, all three of the vertices of a face will have the same normal. For example, if
the vertices of
face[1]
and the two faces share
in
normal[2] face[2]
faces of the mesh.
If the parameter is set to
style
number of faces to which it belongs, and the three vertices of a face can have different normals.
Each vertex normal is the average of the face normals of all of the faces that share the vertex. Use
of the parameter results in a more rounded appearance of the faces of the mesh, except at
#smooth
the outer edges of the faces at the silhouette of the mesh, which are still sharp.
A vertex normal is a direction vector which indicates the "forward" direction of a vertex. If the
vertex normal points toward the camera, the colors displayed in the area of the mesh controlled by
that normal are determined by the shader. If the vertex normal points away from the camera, the
area of the mesh controlled by that normal will be non-visible.
After using the

Parameters
Required. A symbol that specifies the style of the vertex.

Example
The following statement calculates vertex normals for the model resource named FloorMesh. The
parameter is set to
