Hi Kirby, Have you also looked at Soya? I don't think it has come up in this conversation.
http://home.gna.org/oomadness/en/soya/index.html Soya 3D is a very high level 3D engine for Python. Soya aims at being to 3D what Python is to programming : fast to learn, easy to use, while keeping good performances ! Our goal is to propose a complete architecture to realise Free (GPL) games with professional quality entierely in Python. It seems to cover similar territory to Panda3D, but it is more of a grassroots community creation. I haven't gotten into either far enough to really say which one is better, although Soya's definitely the tougher install. --Tom On 5/8/06, kirby urner <[EMAIL PROTECTED]> wrote: > So I think the first thing will be to write a new subclass of writer, > as I've already done for VRML, VRML2, EIG, POV-Ray, and Live3D.[1] > > There's already an Egg API that will allow me to avoid low-level > bricking in with strings (no direct eggfile.write('stuff')).
