28 | * This interface is equivalent to the GM_Surface specified in <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=26012"
|
||
29 | * >ISO 19107</a>. Surface is a subclass of {@link Primitive} and is the basis
|
||
30 | * for 2-dimensional geometry. Unorientable surfaces such as the M�bius band
|
||
31 | * are not allowed.
|
||
32 | * <p/>
|
||
33 | * <p>
|
||
34 | * The orientation of a surface chooses an "up" direction through the choice of
|
||
35 | * the upward normal, which, if the surface is not a cycle, is the side of the
|
||
36 | * surface from which the exterior boundary appears counterclockwise. Reversal
|
||
37 | * of the surface orientation reverses the curve orientation of each boundary
|
||
38 | * component, and interchanges the conceptual "up" and "down" direction of the
|
||
39 | * surface.
|
||
40 | * </p>
|
||
41 | * <p>
|
||
42 | * If the surface is the boundary of a solid, the "up" direction is usually
|
||
43 | * outward. For closed surfaces, which have no boundary, the up direction is
|
||
44 | * that of the surface patches, which must be consistent with one another.
