Method Detail

hitTest3D

boolean hitTest3D(IPoint queryPoint,
                  double searchRadius,
                  int geometryPart,
                  IPoint hitPoint,
                  double[] hitDistance,
                  int[] hitPartIndex,
                  int[] hitSegmentIndex)
                  throws IOException,
                         AutomationException

Locates a part of a geometry closest to a query point. Any located part must be within searchRadius units from the query point.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

queryPoint - A reference to a com.esri.arcgis.geometry.IPoint (in)

searchRadius - The searchRadius (in)

geometryPart - A com.esri.arcgis.geometry.esriGeometryHitPartType constant (in)

hitPoint - A reference to a com.esri.arcgis.geometry.IPoint (in)

hitDistance - The hitDistance (in/out: use single element array)

hitPartIndex - The hitPartIndex (in/out: use single element array)

hitSegmentIndex - The hitSegmentIndex (in/out: use single element array)

Returns:

The bHit

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

hitTestCone

boolean hitTestCone(IRay pQueryRay,
                    double minAngle,
                    int geometryPart,
                    IPoint pHitPoint,
                    double[] pHitDistance,
                    int[] pHitPartIndex,
                    int[] pHitSegmentIndex)
                    throws IOException,
                           AutomationException

Locates a part of a geometry closest to a query ray.
