Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Hi John, Do your volume's samples form a cube (e.g., 64 x 64 x 64), or does the z-face have fewer samples? VisAD's volume rendering performs less well with uneven sample lengths, such as 512 x 512 x 5. -Curtis At 02:19 PM 2/13/2003, you wrote: >Bill: > >I want to add that the 3D rendering only disappears when some "largish" >portion of the z-face is showing.
