We are looking for public domain voxel-based volume visualization
programs with source code. It would be ideal if the code is portable
between different Unix boxes.

The software should be voxel-based rather than surface shaded or wire
frame. The software needs to generate images from  volumetric data sets.
The resulting images are calculated as projections through the volume
where each value of each voxel contributes to the resulting image. This
is different than software which allows you to determine an artificial
threshold and then draws shell-like surfaces on those thresholded areas.
The software we need should be similar to the commercial program
VoxelView, by Vital Images of Fairfield IA. We really need the rendering
engine rather than the display/interface code.

Is there any public domain code that is similar to what we need?

Thanks in advance!

I would also be interested if anyone has any information regarding
public domain (or other) volume reconstruction programs/source code.
I am especially looking for a program and/or code that can handle the
volume rendering of (potentially) several _HUNDRED_ 8-bit 512x512
(or slightly lower resolution) images and can run under UNIX (I am
currently using VoxelView on a Silicon Graphics Workstation but also
have access to SUNs and IBM RISC 6000s).

Thanks,

It is not public domain -- but KHOROS' 3dtools will do the job.  You might
also look into AVS -- they acquired SUN's volume rendering code -- perhaps
not public domain -- but potentially your best bet for good quality images.
