Is there anyway to use the VolumeToGeom module without Alpha bitplanes?


I have a 4D35TG on which ginv gives:

Screen Resolution:  1280 x 1024 pixels.
Zbuffer Resolution: 0xFF800000 min  0x7FFFFF max.
No Accumulation Buffer present.
Alpha bitplanes in DoubleBuffered: 0, SingleBuffered: 0
Red   bitplanes in DoubleBuffered: 4, SingleBuffered: 8
Green bitplanes in DoubleBuffered: 4, SingleBuffered: 8
Blue  bitplanes in DoubleBuffered: 4, SingleBuffered: 8
Zbuffer  bitplanes present: 24
Stencil  bitplanes present: 0
Overlay  bitplanes present: 4
PopUp    bitplanes present: 2
Underlay bitplanes present: 4
User-defined Clipping Planes present: 0
antialiased points available in colormap
antialiased points not available in RGB
antialiased lines available in colormap
antialiased lines not available in RGB
antialiased polygons not available in RGB
Number of verticies per polygon allowed: 256.

The important point here is the 0 Alpha bitplanes.

I would even be interested in something slow and non-interactive like
a translation to a format understood by one of the PD ray-tracing
packages.


Assuming no luck on the above, can a 4D35/TG be upgraded to have
Alpha bitplanes? (I haven't bothered to call my Sales person yet :^) )

Thanks for any information.
