I thought I would share some of my research into external 3D tools, so
there is a new page on the Croquet wiki at
or go to the wiki at http://croquet.doit.wisc.edu/wiki
then select the
FAQ and the "What are some external 3D content creation tools?" item.
This was kind of a pain to convert from my TiddlyWiki, so I'm not sure
how up to date it will stay. Feel free to add to the list.
