This is a mystery.  VisAD actually extracts the BufferedImage
from Java3D in visad.java3d.VisADCanvasJ3D.postSwap(), where
the BufferedImage is constructed with TYPE_INT_RGB.

As a test, I put a:


inside the while(true) loop in (the Java3D
getImage() test) and got '1', which represents TYPE_INT_RGB.
[I did the same thing in (the Java2D getImage()
test) and got '4', which represents TYPE_INT_BGR.]

So I don't know where your TYPE_USHORT_565_RGB is coming from.

However, Don Murray has been writing applications that save
Java3D displays to JPEG files, so perhaps he can give you some
