Hi Anirban, Actually, i have overridden the postSwap and preRender methods of the extended Canvas3D class. I have a flag for writing the image to a JPEG file. I am able to change the background color from black to white and get the JPEG image which reflects this change. However, when i change t

Hi, I think the problem is that you didn't set stripCountArray and countourCountArray by the methods, setStripCounts(int[]) and setContourCounts(int []), before you extracted the GeometryArray from GeometryInfo.   Greg  - Original Message - From: Frank Bellegarde To: [

Desiree, Perhaps you have the influencing bounds for the light incorrect? (i.e. part of your surface is going beyond the scope of the light) - John Wright Starfire Research Desiree Hilbring wrote: > > Hi, > I have one AmbientLight and one DirectionalLight in my scene. > I try to lit a surface,

Dave, It's been a LONG time since I looked at Java 3D's morphing, but as I recall the models you want to morph between must have the EXACT same number of vertices. That might be the real issue you are hitting. - John Wright Starfire Research Dave Murphy wrote: > > Hi there, > > A member of my

Re: [JAVA3D] Graphics card

As the others have noted the cards you are testing with are somewhat out of date (only the GeForce 2 MX-400 is a "modern" card). But from the little you describe of your application I suspect you are largely bound by the CPU speed. If you were placing a lot of textures then you'd see more of a d

Re: [JAVA3D] Changing text color on Canvas3D during rendering

This is what I guess, give it a try -   In the Canvas3D class there is a method called postSwap() which gets called in the rendering loop. Whenever you change some ColoringAttribute associated with a raster/texture, it will be in effect when the postSwap() gets called after your change. So if
