Question #176993 on Yade changed: https://answers.launchpad.net/yade/+question/176993
Status: Open => Answered Jan Stránský proposed the following answer: Hi Ning, I was looking on the Omega class, and it should be no problem to modify it to contain several scenes and the possibility to switch arbitrarily between them, I try and test it and inform you about the progress :-) Jan ceguo píše v Po 06. 02. 2012 v 09:30 +0000: > Question #176993 on Yade changed: > https://answers.launchpad.net/yade/+question/176993 > > Status: Answered => Open > > ceguo is still having a problem: > Hi, > > I still need an answer in this question.
