This one goes in general for picking use the PickRay object and then make sure that you use the transform3d from getVtoLocalWorld transform transform your points that you want to pick then, if you want to set a tolerance you can do it easily with a quad take your point that is now transformed say 1,2,3 and created a quad around that point with your tolerance float TOLERANCE_HALF = .05 Point3d tPoint //transformed point quad (just deal with x,y positions) [0] = tPoint.x - TOLERANCE_HALF, tPoint.y + TOLERANCE_HALF,tPoint.z [1] = tPoint.x + TOLERANCE_HALF, tPoint.y + TOLERANCE_HALF, tPoint.z [2] = tPoint.x + TOLERANCE_HALF, tPoint.y - TOLERANCE_HALF,tPoint.z [3] = tPoint.x - TOLERANCE_HALF,tPoint.y - TOLERANCE_HALF,tPoint.z then do an intersect with that quad you can modify the tolerance anyway you want then Scott Scott Decker Research Scientist Pacific Northwest National Labs [EMAIL PROTECTED] ===================================================================== To subscribe/unsubscribe, send mail to [EMAIL PROTECTED] Java 3D Home Page: http://java.sun.com/products/java-media/3D/
