The alpha is the percent of the q1 that is used, 1-alpha is the percent of q2 that is used.

Is there a simple way in Java3D to average rotations? I looked at the Quat4d's interpolate() method but im not sure what the parameters mean. public final void interpolate(Quat4d q1,double alpha) Performs a great circle interpolation between this quaternion and the quaternion parameter and places the result into this quaternion. Parameters: q1 - the other quaternion alpha - the alpha interpolation parameter what is the alpha? does it go from 0 to 1? How does it influence the interpolation? Will it average the rotations? Will i keep asking questions? :-) Thanks Bob Dengle _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
