T-Splines for optimal modeling control with machine precision

http://tsplines.com/t-tools/

"The T-Spline technology addresses some important limitations that are inherent in conventional NURBS surfaces. T-Splines are based on solid mathematical principles. An important practical consideration is that T-Splines are forward and backward compatible with NURBS."
--Dr. Rich Riesenfeld, Pioneer of B-splines in CAD

Ill pay any price to have it in moi, pls consider it.
