EllipsoidSurfaceRegion Class |
This class represents a region of the surface of an Ellipsoid bounded by a closed surface curve.

SyntaxThe EllipsoidSurfaceRegion type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | BoundaryCurve |
Gets the closed curve defining the boundary of the surface region.
|
| Centroid |
Gets the point which represents a single planetodetic location for the overall area of the region.
|
| Holes |
Gets a read only collection of surface regions that denote topological cuts (holes) of this region.
The count of the number of holes is the genus of this surface.
|
| ReferenceSurface |
Gets the reference surface on which the region is represented by a closed boundary curve.
|
Methods| Name | Description | |
|---|---|---|
 | Add |
Adds this region to otherRegion ignoring any holes in either region.
|
| CheckPointInsideRegion |
Checks to see if the given planetodetic point lies inside the boundary and returns a heuristic measure
of how close the point is to the boundary (including distance to any hole boundary).
|
| CheckPointInsideRegionIgnoringHoles |
Checks to see if the given planetodetic point lies inside the boundary, ignoring holes, and returns a heuristic measure
of how close the point is to the boundary.
|
| Complement |
Complements this region, returning the complement and any holes as regions.
|
| ComputeCartographicExtent |
Computes the cartographic bounding box which completely contains the surface region. If the
region contains either pole, the extent will reflect that in the north and south latitude values.
|
| Equals(EllipsoidSurfaceRegion) | Indicates whether the current object is equal to another object of the same type. |
| Equals(Object) |
Indicates whether another object is exactly equal to this instance.
(Overrides ObjectEquals(Object).) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetEllipsoidSurfaceRegion |
Gets the EllipsoidSurfaceRegion.
|
| GetEllipsoidSurfaceRegionHole |
Gets the EllipsoidSurfaceRegionHole.
|
| GetHashCode |
Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table.
(Overrides ObjectGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Intersect |
Intersects this region with otherRegion.
|
| IsPointInsideRegion |
Determines whether the given planetodetic point lies inside the region.
|
| IsPointInsideRegionEpsilon |
Determines whether the given planetodetic point lies inside the region.
|
| IsPointInsideRegionIgnoringHoles |
Determines whether the given planetodetic point lies inside the region, ignoring any holes.
|
| IsPointInsideRegionIgnoringHolesEpsilon |
Determines whether the given planetodetic point lies inside the region, ignoring any holes.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
 | Reduce |
Takes a set of input surface regions and reduces them down to the minimum set of regions covering the same surface locations.
|
| RotationDirection |
Computes the rotation sense of the region.
|
| Subtract |
Subtracts otherRegion from this region.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
