New question #687331 on Yade: https://answers.launchpad.net/yade/+question/687331
Hey, I read about the orientation of particle from the document but the description is not explicit. It says that the orientation is represented by a quaternion, which could be denoted as ((x, y, z),w). But how is each component defined? 1. In mathematics, each of the component of the quaternion ranges from -1 to 1, and x**2+y**2+z**2+w**2=1. Is that true in YADE? is the w component a radians or a real number? 2. If I input a orientation out of the range ,let's say, a.state.orientation=(10,10,10,10),how will the code responds? Thanks a lot ! -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
