* This interface is equivalent to the GM_OrientablePrimitive specified in
|

* <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=26012">ISO 19107</a>.
|
34 |
* Orientable primitives are those that can be mirrored into new
|
35 |
* geometric objects in terms of their internal local coordinate
|
36 |
* systems (manifold charts).
|
37 |
* </p>
|
38 |
* <p>
|
39 |
* For curves, the orientation reflects the direction in which the curve is traversed,
|
40 |
* that is, the sense of its parameterization. When used as boundary curves,
|
41 |
* the surface being bounded is to the "left" of the oriented curve.
|
42 |
* </p>
|
43 |
* <p>
|
44 |
* For surfaces, the orientation reflects from which direction the local coordinate
|
45 |
* system can be viewed as right handed, the "top" or the surface being the direction
|
46 |
* of a completing z-axis that would form a right-handed system.
|
47 |
* </p>
|
48 |
* <p>
|
49 |
* When used as a boundary surface, the bounded solid is "below" the surface.
|
50 |
* The orientation of points and solids has no immediate geometric interpretation
|
51 |
* in 3-dimensional space.
|
52 |
* </p>
|
53 |
* <p> OrientablePrimitive objects are essentially references to geometric primitives
|
54 |
* that carry an "orientation" reversal flag (either "+" or "-") that determines whether
|
55 |
* this primitive agrees or disagrees with the orientation of the referenced object.
