[JAVA3D] using j3d on SGI irix 6.5

Hi all, I am thinking about using j3d as API on a SGI V8/irix 6.5. Does anybody know if the stereo mode is working properly? Do I have multipipe support with j3d or any chance to have some in near future? Thank you very much in advance, Hans Egermeier --

Hi What I would do with the AWTEvent is get the coordinates of the mouse when the click occured. Then, you can use the Canvas3D.getImagePlateToVworld(Transform3D t). Then, use the transform3D t on the mouse coordinates to get the virtual world coordinates. At this point, to increase tolerance leve

Re: [JAVA3D] Behavior processStimulus Bug

Well, I have a work around but it won't help unless you call Behavior.setEnable(). In other words, it won't help if you are enabling/disabling the behavior by removing/adding it to the scenegraph or by using a Switch or by setting the schedulingBounds, etc. Here's the workaround: On construction

Re: [JAVA3D] Interleaved array color performance

I've done some more testing. It turned out that color data is copied only when I enable blend transparency for quads. In other case (per-vertex color modulated by texture, non-transparent) color data is copied directly from same array as coordinates and texture coords. With blending it looks like

That's surprising. I haven't had a problem with transparent Rasters. I use a BufferedImage of type BufferedImage.TYPE_4BYTE_ABGR. and an ImageComponent2D of type ImageComponent2D.FORMAT_RGBA. It is necessary to set the TransparencyAttributes of the Shape containing the Raster geometry. For a whil
