Ok.....
I've added the following code to the ColorCube class. It should provide a
valid graphics Configuration for the Canvas3D. Everything compiles without
errors or warnings. There are no warnings or errors at runtime either.
Recent experience though, has shown that this doesn't mean the program is
right, only that it runs on my machine : )
I've re-uploaded the zip file again:
http://dcasteel.freeservers.com/ColorCube.html
//--------------[Set up graphics configuration]---------------------------
GraphicsConfiguration gc;
GraphicsConfiguration[] gcfg;
GraphicsConfigTemplate3D graphicsConfigTemplate3D = new
GraphicsConfigTemplate3D();
GraphicsEnvironment ge =
GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gdev = ge.getScreenDevices();
gcfg = gdev[0].getConfigurations();
int numDev = Array.getLength(gdev);
java.util.ArrayList gcfgList = new java.util.ArrayList();
for(int d=0; d<numDev; d++)
{
gcfg = gdev[d].getConfigurations();
for(int g=0; g<Array.getLength(gcfg); g++)
{
gcfgList.add(gcfg[g]);
};
};
gcfgList.toArray(gcfg);
gc = graphicsConfigTemplate3D.getBestConfiguration(gcfg);
canvas = new PrintCaptureCanvas3D(gc);// <------- pass
the configuration to the canvas

Now I'm puzzled.....
I do have a null graphics configuration (WARNING: Canvas3D constructed with
a null GraphicsConfiguration.)
But should that cause this:
java.lang.IllegalStateException: GeometryArray: must be in COLOR_3 mode to
use this method
I've set the QuadArray to COLOR_3:
xPlaneGeometry = new QuadArray(xquadPoints.length,
QuadArray.COORDINATES|QuadArray.NORMALS|QuadArray.COLOR_3);
I'm not passing normals in, so that setting could be skipped, but it doesn't
seem likely that the lack of normals would cause the error.
The wierd thing is it works great on my system with no errors or warnings at
compile or runtime.
I'll try to fix the null graphics configuration warning, but I don't know
where to look for the problem with the GeometryArray.
