does anyone know if there is any difference in performance between using the PositionPathInterpolator and the TCBSplineInterpolator provided in the utilities package? Basically would using linear intepolation speed up the runtime execution of my program? Any help much appreciated J. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
