Just a note that the SynthEyes 3-D camera tracker has now been tweaked to run on LINUX systems using WINE. The installer isn’t run well by WINE but once it’s in you’re OK. If you run under CodeWeaver’s CrossOver Office, the install runs nicely. I’d be interested in some feedback of how it runs on different Linux distros.
SynthEyes is a commercial app($349) used in many feature films with blender export, naturally. Demo version on site, http://www.ssontech.com
