IProximityOperator3D Interface (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Provides access to members that find the 3D distance between two geometries with Zs.
This interface is new at ArcGIS 9.3.
Returns the point on the input geometry that is closest to the input point, and returns the 3D distance between these two points. In contrast to IProximityOperator, Z values are taken into account when determining whether the given relationship exists.
| Name | Description | |
|---|---|---|
 |
QueryNearestPoint3D | Copies into 'nearest' a point on this geometry nearest to the input point. |
|
ReturnDistance3D | Returns the minimal distance between two geometries. |
|
ReturnNearestPoint3D | Creates and returns a point on this geometry nearest to the input point. |
| Classes | Description |
|---|---|
| Envelope | A rectangle with sides parallel to a coordinate system defining the extent of another geometry; optionally has min and max measure, height and ID attributes. |
| Line | A 2D straight line between a pair of 2D endpoints; can optionally have height, measure and ID attributes at each endpoint. |
| MultiPatch | A collection of surface patches. |
| Multipoint | An ordered collection of points; optionally has measure, height and ID attributes. |
| Point | A two dimensional point, optionally with measure, height, and ID attributes. |
| Polygon | A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes. |
| Polyline | An ordered collection of paths; optionally has measure, height and ID attributes. |
These methods are intended to be called against top-level geometries only (Point, Multipoint, Polyline, Polygon, Envelope, MultiPatch). To call a method against a Segment/Path or Ring, first add the part to a Polyline or Polygon container, respectively, and then call the appropriate method against the container.
These methods treat MultiPatch geometries as shell representations, where the interior is not considered part of the geometry. Consequently, a point situated inside a MultiPatch that does not touch one of its surfaces will be classified as disjoint from that MultiPatch.
