The Halfspace type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | Halfspace(Cartesian, Cartesian) |
Creates Halfspace from circle defined by two
diametrically opposite points. If the two points are
relative poles, then the whole sphere is returned.
|
| Halfspace(Cartesian, Double) |
Creates a halfspace from the center point and the cosine of the angle.
|
| Halfspace(Double, Double, Double) |
Creates a halfspace from center coordinates (RA,Dec) and radius.
|
| Halfspace(Cartesian, Cartesian, Cartesian) |
Creates a halfspace whose edge goes through three specified points.
|
| Halfspace(Cartesian, Double, Double) |
Creates a halfspace from the center point and the cosine and sine of the angle.
|
| Halfspace(Double, Double, Double, Boolean, Double) |
Creates a halfspace from the center point and the cosine of the angle.
|
| Halfspace(Double, Double, Double, Boolean, Double, Double) |
Creates a halfspace from the center point (x,y,z) and the cosine and sine of the angle.
