We are interested in quantifying changes in cell volumes. We use a BioRad 1024 Krypton/Argon LSCM. I would appreciate any recommendations and opinions on software programs for visualization, volume and surface rendering. Volume rendering is the most important factor in the analysis, although the ability to do all three would be a plus. We currently use Windows NT and a Sun or SGI is not an option at this time.
