Class PickingUtils

java.lang.Object
  org.j3d.aviatrix3d.PickingUtils

public class PickingUtils
extends java.lang.Object

Utility functionality for picking management.

This class is particularly useful for classes that are implementing the CustomPickTarget interface and need to get through the basic picking questions of whether a specific pick request intersects the given bounds. From there, the class implementation can then decide how to further process the bounds or children.

Method Detail

checkIntersection

public boolean checkIntersection(BoundingVolume volume,
                                 PickRequest req)

Check the given volume for an intersection based on the request. This will automatically take the request and determine the correct intersection request to make. The picking does not test for the mask flags. It is assumed that the caller will do that before calling this class.

Notes:

• The cone segment intersection doesn't have an equivalent API on BoundingVolume so the request is treated as an infinite request for now.
• The infinite cylinder picking does not have an equivalent API on BoundingVolume so the request is treated as a segment request for now.

Parameters:

volume - The volume to be tested for the pick intersection

req - The request to process the pick intersection testing with
