Deformation-based data reduction of Time-Varying Meshes for displaying on mobile terminals

摘要

In this paper, a drastical compression method for Time-Varying Meshes (TVMs) is presented aiming at displaying on mobile terminals, where the resources are quite limited. In addition to our previous work of the skeleton-based temporal compression for TVMs, we have implemented spatial compression using 3D model morphing and mesh simplification. In addition, we have developed an interface for skeleton adjustment and modified the skeleton-based motion analysis so that rotation motion can be represented properly. As a result, we have achieved a very high compression rate of 1/5,000 and the rendering speed has been enhanced by six times as compred to our previous method. The feasibility of the algorithm has been confirmed on an actual cell phone.
