G'day, A good starting point for commercial and/or public domain 3D reconstruction software is the 3D Reconstruction Web-page: http://biocomp.arc.nasa.gov:80/3dreconstruction/ and of course Lance Ladic's confocal microscopy pages has a sectiondevoted to 3D reconstrcution software: http://www.cs.ubc.ca/spider/ladic/software.html Here at the BCMRC we use AVS (commercial) and have found it to be excellent for 3D reconstrction.
