[Bf-committers] softbody experiments

[David Bourguignon]

Hi Ton,

I will be there for discussing softbodies at 17h CEST (I guess that's Paris time...) on the usual IRC channel.

I perfectly agree with you concerning the physical realism vs. artist control issue.
I had this in mind at the time I designed my deformable model.

Talk to you soon,

David.
