Leyland,
The following bug will prevent you from using PickCone or PickCylinder
to do what you hope to achieve :
BugId 4351050. - PickTool is partially broken for PickCone and PickCylinder :
The current Shape3D.intersect() API doesn't return the distance for
PickCone and PickCylinder.
This bug will be fixed in the future j3d1.3 release.

> Subject: [JAVA3D] PickBounds and picking for collision detection...
> To: [EMAIL PROTECTED]
>
> In the java3d-1_2_1-doc files, under PickTool class, it says that...
>
> "If the pick shape is a PickBounds, the pick result will contain only the
> scene graph path, even if the mode is GEOMETRY_INTERSECT_INFO."
>
> Does this also apply to using setShapeConeRay, setShapeConeSegment,
> setShapeCylinderRay, setShapeCylinderSegment?
>
> The information I want to generate is the distance down the ray the collision
> occures.
>
> I want to have a more volume for collision avoidance. Right now I am using a
> PickRay via setShapeRay in PickTool. This obviously has problems with smaller
> objects (like a pole), in which an object will pass right through another
> object if the center point is not collided with. If any one has any ideas on
> this, let me know.
