14TAB #!EF #!N #!N Functional Details #!N #!N This module computes
15face normals for a surface. A "normals" component is necessary to
16produce shading when an object is rendered. In contrast to the
17output of the Normals module, the normals produced by this module
18are always connection dependent rather than position dependent. Therefore, when they
19are rendered, the result is faceted shading. #!N #!N When this
20module is used, any colors that reside at vertices are averaged
21for each face at the time of rendering, resulting in a
22single color for each face. #!N #!N The FaceNormals module assumes
23that the triangles or quads have consistent point orderings (i.e., so
24that the directions of the face normals will be consistent throughout
25the mesh). #!N #!N The Shade module can also be used
26to compute normals for shading. #!N #!N Components #!N #!N Creates
27a "normals" component that is dependent on connections. All other components
28are propagated to the output. #!N #!N Example Visual Program #!CForestGreen
