[JAVA3D] pick object

Hi.. Supposed that I have a class extended from Shape3D. I want to retrieve objects from that class by using PickObject class. If I use PickObject.pickAllSorted(x,y, PickObject.USE_GEOMETRY), I got message "no capability set for allowing intersect". If I don't specify any flag, the result is null

[JAVA3D] Simple Universe Pls read the problem and suggest something.

I recieved answers for the alternatives to Simple Universe and i am thankfull for that. If some one could tell me how i can change the branchgroup at run time through mouse or keyboard, such that if an object is created of 27 cubelets and i want to select a layer of nine & apply a rotation on them

[JAVA3D] Loading in textures

I am trying to load in a VRML file or 3DS file that have textures attached to it.  So far I have been unsuccessfull in getting the textures to show up in my virtual world.  I don't know if I have to do any additional work or if I rely on the loader to do all the necessary work to allow the t

[JAVA3D] Understand the units that Java3D uses

I am having a difficult time understanding what units Java3D works in.  I have read that a 1.0f unit is equivalent to 1 meter in the physical world, so I am using that as a basis for setting up my initia viewpoint and my boundary plane for manipulating the object.  Can someone help me unders

Re: [JAVA3D] Why Adobe?

I was just thinking the same thing but for different reasons.. I currently only have Net access at work, and I can only find one floppy disk to get the tutorial home on :P An HTML or Text version would be much smaller and let me fit it on a single disk. Hmm. Maybe something is trying to tell me

Re: [JAVA3D] Loading in textures

Hi Dean,   I think your problem probably comes from the lack of lighting in your virtual world.  If you don't have any lights then try adding one.  Suns Java3D tutorial chapter 6 covers lights pretty good.   Here is an example for addition of basic ambient lighting to BranchGroup root     /* add

Re: [JAVA3D] Gourard shading: what is the interpolation?: The answer.

  With help from Dennis Bouvier, I've fixed the problem.   I was mapping values linearly to a subset of HSVA dimensions -- because of re-use of a color mapper for previous problem -- but that's not a linear mapping in RGBA space. For example, the graph of values mapped to hues was an arc of

Re: [JAVA3D] pick object

Tria, I'm going from memory here, but if I recall, in order to use "USE_GEOMETRY" in pickAllSorted, you need to first iterate throughout all your (Shape3D) nodes in your scene (or the subgraph under PickObject) and set the capability Geometry.ALLOW_INTERSECT. Thus for every node that you know to

Re: [JAVA3D] IllegalSharingException: SharedGroup: Illegal leaf nodes ??

Actually since the code is in Open Source and people are using it to develop X3D, the best thing to do would be to track the bug and fix it. Please send me a copy of the test case too. Regards, __ Rick Goldberg - Member Technical Staff Sun Microsystems Graphi

(Please forgive me if this seems like venting) After getting the KeyNavigatorBehavior working, I've come to the conclusion that it needs a LOT of work to make it practical. First performance takes a MAJOR nosedive, granted I'm working on slow machines, (100 & 133Mhz) but the operation of the appl

This was exactly my experience as well. See the discussion several weeks ago in this same mailing list, entitled "KeyNavigatorBehavior and thrashing". The start of the message thread was from me on Oct. 15. I'm speculating that KeyNavigatorBehavior was written quickly for occasional use naviga

Re: [JAVA3D] Vote for heavyweight JInternalFrames (for Java3D) ...

You can use JInternalFrames and add a Canvas3D to it. I've got an application that does that. But, I am only using SimpleUniverse, so possily there is some other limitation there that I am not hitting. -- Adam Belmont Andrew R. Thomas-Cramer writes: > ... in Sun's bug database for bug 4154448
