Volume warping

Abstract

Volume warping, a technique for deforming sampled volumetric data using B-splines that is related to image warping and to the free-form deformations of T.W. Sederberg and S.R. Parry (1986) and S. Coquillart (1990), is presented. The process is accelerated to near-real-time speed, and the compromises that are made to effect such speeds are explained. This technique expands the repertoire of volumetric modeling techniques and can be applied to any form of volumetric data.<>
