Twisted Faces
Faces that self-overlap due to a 180-degree twist can also produce ambiguous
results, because the normal for the face is not well defined.
In the following example, artifacts appear where the face is twisted due to
crossing the second and third corner points.
This situation is often encountered when trying to fix a model that has a hole
in its surface. For example, when corner points are selected for the new face,
the points are crossed instead of being placed around the hole in a
counter-clockwise direction. Avoid this problem by choosing corner points
in the proper order.

RENDER
Creates a photorealistic or realistically shaded image of a 3D solid or surface
model.
Balance Mesh Density for Smooth Geometry
When you render a model, the density of the mesh affects the smoothness of
surfaces.
Mesh components are comprised of vertices, faces, polygons, and edges.
■ A vertex is a point that forms the corner of a face or polygon.
■ A face is a triangular portion of a surface object.
