* Surface is a subclass of {@link Primitive} and is the basis for 2-dimensional geometry.
|
35 |
* Unorientable surfaces such as the M?bius band are not allowed.
|
36 |
* <p/>
|
37 |
* <p>
|
38 |
* The orientation of a surface chooses an "up" direction through the choice of the upward normal,
|
39 |
* which, if the surface is not a cycle, is the side of the surface from which the exterior boundary
|
40 |
* appears counterclockwise. Reversal of the surface orientation reverses the curve orientation of
|
41 |
* each boundary component, and interchanges the conceptual "up" and "down" direction of the surface.
|
42 |
* </p>
|
43 |
* <p>
|
44 |
* If the surface is the boundary of a solid, the "up" direction is usually outward.
|
45 |
* For closed surfaces, which have no boundary, the up direction is that of the surface patches,
|
46 |
* which must be consistent with one another.
