Hierarchical Feature-Based Volume Morphing

Abstract

Morphing techniques have been broadly applied in many fields to create astounding visual effects. In this paper, a hierarchical feature-based volume morphing algorithm is presented. Anew type of feature element, the cylinder field, is proposed to facilitate the task of feature specification and corresponding. In order to interpolate object shapes smoothly, Distance Field Interpolation (DFI) is employed in our algorithm. Furthermore, the idea of feature-element hierarchy is leveraged to improve the morphing effect significantly.
