Method Summary

void	pick(java.lang.Object object, boolean asNode, Point3d origin, Vector3d direction, Matrix4d transformation, PickList list) Computes intersections of a given ray with this shape.

Method Detail

pick

void pick(java.lang.Object object,
          boolean asNode,
          Point3d origin,
          Vector3d direction,
          Matrix4d transformation,
          PickList list)

Computes intersections of a given ray with this shape.

Parameters:

object - the object of which this shape is an attribute

asNode - true iff object is a node

origin - the origin of the ray, in local coordinates

direction - the direction of the ray, in local coordinates

transformation - the transformation from local coordinates to world coordinates

list - the list to which intersections have to be added
