Hi, In the javax.vecmath's quaternion the interpolation function uses the great circle interpolation. And the Java3D's TCB interpolation also uses the great circle spherical interpolation.
I was looking for some papers about quaternion intepolation using TCB (Tension-Continuity-Bias) BSplines. Up to now, the closest thing about it I could found is : http://www.cs.vassar.edu/~ellman/old-courses/395-spring-2001/cs395-lecture11.pdf Alessandro ______________________________________________________________________ Yahoo!
