[JAVA3D] simple view rotation

I am new to Java 3D and have a simple problem to solve - that I can't! All I'm trying to do is change the view position around the origin by clicking buttons, so I change from the default (+ve Z) front view, to the side, back, top and bottom views. I can transform the view using the Transform3D

[JAVA3D] selecting objects within mouse windows

Hi all; I want to select the Java3D objects by opening a window by mouse. Is this possible? I don't want to select objects one by one. Can anyone give me a hint or an example code? Thanks Ali === To unsubscribe, send email

Re: [JAVA3D] selecting objects within mouse windows

Hi Ali, What do you mean by selecting the Java3d objects? if you mean to highlight/rotate/?.. the java3d objects in your scene, you can do it programatically by traversing the Scene Graph for your type of objects( you can categorise the Java3d shapes if you need by extending the Shape3D class an

I'm using the PickTranslateBehavior class to move vrml objects in my scene. I've got a floor/ceiling/walls vrml file and a table vrml file, and things on the table. I have set the capability for only the objects on the table to allow picking : setCapability( TransformGroup.ENABLE_PICK_REPORTI

Re: [JAVA3D] PickTranslateBehavior

I figured out the problem thanks to Justin Couch's article at http://www.j3d.org/tutorials/raw_j3d/chapter6/picking.html I wasn't calling the the setPickable(false) method of the Node class for the table and ceiling/walls/floor. I'm assuming that whenever I clicked the mouse, either the table

[JAVA3D] Questions about status of j3d.org, j3d and more...

Hi. What is the status of j3d.org code? The version 0.6 is dated february 2002. What improvements, if any, have been done to the code since that date? Is actual code enough stable to try to use it? Second question. I have understood that the development of J3D 1.4 will have been a little differ

Hi Carsten, Actually the window just hide when close so removeNotify() didn't get through Java3D to cleanup the canvas. A better fix is to add ef.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); (default is HIDE_ON_CLOSE) instead of my previous suggestion when only cleanup when A

[JAVA3D] Transformgroups, and mouse behaviors

A couple questions I was hoping you all could help me with: I'm attempting to add different objects dynamically to a scene. 1) Within my class, I can create a TransformGroup, and add a shape3D to it; however, outside that class, I have a getTransformGroup method that returns said TransformGroup

Hi Justin, Both loader.java and LoaderDemo.java have the same behavior in my machine. They can not load Hanim files. It is OK to load non-Hanim files from both exapmles. However, when the obj (ex. BoxConeSphere.wrl from web3d exapmles) is rotated by dragging left mouse button, it outputs this mes
