[JAVA3D] Compressing a tree of BranchGroups and TransformGroups

Allow I have a deeply nested tree of BranchGroups off which are hanging TransformGroups with attached Shape3Ds. What I'd like to do is "compress" the whole tree into one BranchGroup containing all the Shape3Ds. It seems to me that this must be possible by creating a new top level BranchGroup, wa

Re: [JAVA3D] Off-Axis Projection and Multi-Screen configurations

This describes my problem exactly, I believe the answer involves changing the imageplate using the headtracked configuration. There is an example of Java3D in a CAVE in a paper that was published in the May/June 1999 issue of IEEE called "Projects in VR" : The Java3D API and VR. Could we please h

Re: [JAVA3D] second try: euler-angles

from previous message I know I could uses matrix-algebra -> A_relative = B_absolute * (A_absolute)inverse But then I cannot deduce the individual euler angle components from the resulting matrix. Is there a way to achieve this ? Now that you have matrix A_relative (A[ ] ), you can interrogate t

[JAVA3D] cult3d vs java3d

Hello! I have been looking at something called cult3d. Basically it is a plugin whic allows you to display an interactive 3d model on your website. (if you are curius just check out www.cult3d.com ) It doesn't cost anything to get the plugin, but if you want to display a model built in the cult

Re: [JAVA3D] Off-Axis Projection and Multi-Screen configurations

There have been several more posts on the subject but no response from Sun  I don't know if this has fallen on deaf ears, or if I failed to explain the problem well enough.  So I will attempt again. I have three machines, therefore three JVM's, three View's and three Canvas3d's that need to work

Re: [JAVA3D] java.lang.OutOfMemoryError

I have a rather large app with many items in the scenegraph and having an OutOfMemoryError is not uncommon to me. It IS quite frustrating. I try to design optimized code and utilize the command line optimizations and I've come to the conclusion that it's going to be a part of my code. The thing

Re: [JAVA3D] java.lang.OutOfMemoryError

Try looking in the java3d faq (j3d.org) and the archives of this mail list. the solution is to increase the memory allocated to the jvm by including a statement like -Xmx200m (to allocate 200 meg) -Original Message- From: b. white [mailto:[EMAIL PROTECTED]] Sent: Friday, June 30, 2000 11

[JAVA3D] Java 3D 1.2 OpenGL acceleration under Windows

Rats, now that really stumps me... actually I've been wanting to get 'transparent' hardware accelerated OpenGL support ever since. Like when I was coding Delphi apps that use an OpenGL binding. However for the latter case, i had to specifiy the particular DLL to use (opengl32.dll and glu32.dll)

[JAVA3D] java.lang.OutOfMemoryError

I submitted a few questions related to the java.lang.OutOfMemoryError a few weeks ago. I have now encountered it again in another app I am designing. I haven't yet been able to determine if this is a java/j3d problem, or a mistake I am making in my code. If anyone else has encountered this p

Hi, I posted a question yesterday. And I got two answers which are very helpful. I really appreciate these people's kindness. Here I have another question. I tried to use the Java 3D view model to change the view volume and failed. I am familiar with OpenGL view model so I used the following co

[JAVA3D] second try: euler-angles

Hi, I posted a similar question a while ago. Suppose ColorCube A has a certain rottaion specified in euler angles. ColorCube B also has a certain rotation specified in euler angles. These individual rotations are then put in a Transform3D object and passed to a TransformGroup object. How do I c

[JAVA3D] Benchmarks

I was searching for benchmarks for Java3D (or OpenGL) but i didn't find very much. Tornadolabs has done one, but it's not what i was looking for. I wondered how many polygons a scene may have, how lights, transparency and textures influence the frame rate. How fast are Behaviours? Which background
