[JAVA3D] TextureColorTable

Hi All, Just trying to glean some info about the TextureColorTable feature in TextureAttributes. Tried looking thru' the OpenGL1.3 spec. but couldn't seem to locate any details. Anyone using this feature and/or aware of a (pc) gfx card that supports this ? Regards Vaidya ==

[JAVA3D] Java 3D Birds of a Feather Session at Siggraph 2002

Hi All, I just wanted to give everyone an early heads up. We will have a Java 3D Birds of a Feather session at Siggraph this year. It is Tuesday night from 6:30pm to 8:00pm at the convention center. The main topic will most likely be Java 3D 1.4, but we will be willing to talk about just about

[JAVA3D] Inventor/VRML1 loader

Hi everyone, I currently use VRML97 files for my models. An important customer insists on using .iv Inventor file format. Has anyone written such a loader? Or a VRML1 loader I could modify? I checked the j3d page but saw none. Josh Joshua L

Marcel,   You are adding the a child to BranchGroup AFTER you attach it in Simple Universe. This should be BEFORE. this way:   // Second and LAST addChild in the BranchGroup  component.addChild(new Sphere (0.2f, new Appearance()));       createSceneLight(component);       Can

Re: [JAVA3D] WinNT Bluescreen

Title: RE: [JAVA3D] WinNT Bluescreen Brett, This is more than likely a graphics card compatibility problem.  (I have seen all manner of crashes, lockups, display artifacts, and general mayhem when running Java 3D apps, and almost all were tracked down to the graphics card.) You said your gr

[JAVA3D] RestrictedAccessException

Why the  instruction at Test.createCanvasPanel(Test.java:52), generate a RestrictedAccessException (javax.media.j3d.RestrictedAccessException: Group: only a BranchGroup node may be added ), if the variable component is a BranchGroup ? Why the first addChild(Sphere) don't generate this except

[JAVA3D] How do texture formats work?

I am having a bit of a problem understanding how to use the different Texture formats available. The javadoc says something like this: javax.media.j3d.Texture Format - the data format. The format is one of the following: INTENSITY - the texture image contains only texture values. LUMINANCE -

[JAVA3D] Difference between physical and virtual world?

I'm getting a bit confused when reading the Java3D API documentation about the class "View"... What are the differences between the physical and the virtual world (or physical and virtual coordinates) ? Thanks. === To unsub

Re: [JAVA3D] Who to ping for OS X + Java3D

Who stands to reap immediate monetary benefits if Apple opts for the license ? Sun ? If so, wouldn't Sun route some more funds to the Java 3D group ? Well, even if it is not the extra funds, anything that will facilitate Java 3D to "thrive longer and prosper", I am for it :) Vaidya >On Tue, 4

[JAVA3D] Text display resolution

Hi, I am using a Shape3D object which internally holds a Texture2D object for drawing text on a Canvas3D object. The text is drawn using font "Tahoma". This Canvas3D object displays a wireframe model. The problem is, when the model dimensions are very small, the text's display resolution is ver

Re: [JAVA3D] Who to ping for OS X + Java3D

Hi, sometimes ago I found on the gl4java site a link to a library called j-Free-D. It is a Java 3D implementation using GL4Java. And GL4Java runs on MacOS. However, the web-site of j-Free-D is dead and j-Free-D only implements java3d 1.1. I could only find a tar archive with it. I don't know how

Re: [JAVA3D] When does Java 3D use native code?

Hi all. This is my question on a similar subject: I would like to know how Java3D links to OpenGL. I posted a similar message here in the list in April, and Mauricio Vices reply to me (thanks, Mauricio), but I still am not sure about how this works. The question is: I know I have at least 2 Op
