Class DefaultGeometryPickTester

java.lang.Object
  org.xith3d.picking.DefaultGeometryPickTester

All Implemented Interfaces:

GeometryPickTester

public class DefaultGeometryPickTester
extends java.lang.Object
implements GeometryPickTester

Geometry-ray intersection test is accessed by PickingLibrary trough an interface instead of an internal method to make it replaceable. This is the default implementation.

Method Summary

float

testGeometryIntersection(PickResult pickCandidate, org.openmali.vecmath2.Ray3f pickRay, float closestIntersection, boolean testIntersectionsInWorldSpace, org.openmali.spatial.polygons.Triangle bufferTriangle) Test the candidate's geometry for ray intersection.

                                      org.openmali.vecmath2.Ray3f pickRay,

                                      org.openmali.spatial.polygons.Triangle bufferTriangle)

Test the candidate's geometry for ray intersection. Implementations must set the minimumDistance or the pickCandidate!

Specified by:

testGeometryIntersection in interface GeometryPickTester

Parameters:

pickCandidate - the cadidate PickResult, which's geometry is tested for ray intersection

pickRay - the transformed pick ray

closestIntersection - the closest so far intersection (for optimizations)

testIntersectionsInWorldSpace - whether or not to test picking intersections in world space

Returns:

the distance of the intersection or <0 for no intersection
