Re: [JAVA3D] Picking - all help is appreciated

Correct me if I am wrong but are you asking how to get the Z coordinate for a blank point into which you click?   Cos that would be senseless. Picking I think requires that you actually pick an object in the world since that object has an attributed x, y and z location, whereas just clicking into nothing on the canvas3D has no way of determining how far along the Z axis the click was.   The Picking classes have get methods which return Point3D objects from which you can get your x, y, z but these will need an object.   ^^^^^^^^^^^^^^^^^^^^^ Allistair D Crossley IT Consultant (Logica) 01277 252088 [EMAIL PROTECTED] ^^^^^^^^^^^^^^^^^^^^^ -----Original Message----- From: Bruno Sousa Caiado [mailto:[EMAIL PROTECTED]] Sent: 20 July 2000 15:08 To: [EMAIL PROTECTED] Subject: [JAVA3D] Picking - all help is appreciated Hello. I�m sorry for the "desperate" subject but i�m loosing my mind with this problem...   What i�m trying to do is to find out the (x,y,z) of a point when i click a mouse button   Finding out x and y is easy with the MouseEvent class.My problem is knowing the z value! If the mouse is clicked on top of an object that�s has z=10 in that point how can i find out this value?   All help is appreciated....   Thank you and keep up the good work   Bruno Caiado
