TAB #!EF #!N #!N Functional Details #!N #!N This module computes
face normals for a surface. A "normals" component is necessary to
produce shading when an object is rendered. In contrast to the
output of the Normals module, the normals produced by this module
are always connection dependent rather than position dependent. Therefore, when they
are rendered, the result is faceted shading. #!N #!N When this
module is used, any colors that reside at vertices are averaged
for each face at the time of rendering, resulting in a
single color for each face. #!N #!N The FaceNormals module assumes
that the triangles or quads have consistent point orderings (i.e., so
that the directions of the face normals will be consistent throughout
the mesh). #!N #!N The Shade module can also be used
to compute normals for shading. #!N #!N Components #!N #!N Creates
a "normals" component that is dependent on connections. All other components
are propagated to the output. #!N #!N Example Visual Program #!CForestGreen
