Re: [JAVA3D] MousePick!

[Ra�l]

In many applications an event occurs when the mouse pointer is on an object for a time, is it possible to do something similar in Java 3D?.   Thanks. (and sorry for mi english please). ----- Original Message ----- From: Eric Reiss To: [EMAIL PROTECTED] Sent: Wednesday, November 21, 2001 7:20 PM Subject: Re: [JAVA3D] MousePick! sorry, i need to clarify one thing. I haven't been actively doing any Java3D and forgot that the callback method is implemented in the picking versions of those three behaviors.  So what I was talking about would require using the extended picking versions of those three behaviors. The Sun examples show the basics of implementing the callback method for the picking mouse behaviors. Sorry for needing to make a follow-up post. At 01:13 PM 11/21/2001 -0500, you wrote: Each of the three behaviors you mentioned has a callback method which when setup returns the transformgroup of the object that was zoomed, translated, or rotated. From this transformgroup, you can get the Transform3D and hence the three coordinates. If you want to simply get the three coordinates without causing the position / orientation of the object to change, this is a little different. You would need to right your own behavior.  I have modified the three behaviors you mentioned and created one that allows me to retrieve properties of an object without changing the position / orientation.

But I want to find a generic point(x,y,z) in this system. Is it possible to return by mouseclick the three coordinates of this point? Thanks.
