IRelationalOperator3D Interface (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Provides access to members that determine if a certain spatial relationship exists between two geometries with Zs.
This interface is new at ArcGIS 9.3.
Indicates whether two Z-Aware geometries intersect, sharing at least one point in common. In contrast to IRelationalOperator, Z values are taken into account when determining whether the given relationship exists.
| Name | Description | |

 |
Disjoint3D | Indicates if the two geometries share no points in common. Negate this result to compute the Intersect relation. |
| 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. |
| 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.
