| 摘 要： | INTRODUCTION Three dimensional (3D) meshes are widely used to represent 3D objects. With the rapid advances in digital acquisition technology, meshes with millions of vertices are becoming increasingly common. Be- cause of memory constraints and lack of graphics power, visualizations of this magnitude are difficult or impossible to perform even on the most powerful workstations. Therefore, the need for parallel im- plementation is clear. Most previous work in high performance rendering h…

| Abstract: | Use of compressed mesh in parallel rendering architecture is still an unexplored area, the main challenge of which is to partition
and sort the encoded mesh in compression-domain. This paper presents a mesh compression scheme PRMC (Parallel Rendering based
Mesh Compression) supplying encoded meshes that can be partitioned and sorted in parallel rendering system even in encoded-domain.
First, we segment the mesh into submeshes and clip the submeshes’ boundary into Runs, and then piecewise compress the submeshes
and Runs respectively. With the help of several auxiliary index tables, compressed submeshes and Runs can serve as rendering
primitives in parallel rendering system. Based on PRMC, we design and implement a parallel rendering architecture. Compared
with uncompressed representation, experimental results showed that PRMC meshes applied in cluster parallel rendering system
can dramatically reduce the communication requirement.
