What are the pros and cons of these voxel data file formats? .VXL .VOX .KVX .KV6 .V3A .V3B I am trying to decide whether it's worth going with any of the above, or some other, or if I should roll my own. The deciding factors in order of importance are Animation support (I am aware this is a difficult aspect when it comes to voxels), using voxel deltas or numerical transform descriptions. Simplicity (or at least a concise format) Compression From what I can tell, the Tiberian Sun VXL format is the only one which is designed for animation, but Ken Silverman of Voxelstein3D fame claimed that VXL does not support animation (in a single file, were his words). So I wonder if maybe there are not two different .VXL formats, since it seems an obvious choice of file extension for voxel data... could be from a medical imaging context. I do need someone with solid experience of voxel formats to come and comment on the practical pros and cons, in their experience. Consider this question in the same way you might compare JPG to PNG to GIF.
