1. Introduction
With the development of digital design and manufacturing technology, modern engineering modeling and simulation applications have created numerous highly complex 3D models, including industrial CAD models of aircrafts, ships and production plants, etc. These models consume large amounts of storage space and are geometrically complex, which requires superior visual computing capabilities for real-time rendering. Although the hardware performance of commodity PCs has increased constantly according to Moore’s law, it is still not sufficient to render these datasets at interactive frame rates using brute-force approaches. There have been several studies conducted in the field of realtime massive model rendering. OpenRT system was able to render large models at several frames per second using a single commodity desktop PC by combining real-time ray tracing with outof-core caching [1]. Some other research focus on utilizing parallel architecture to accelerate rendering process [2,3], such as Gi-Walk and Manta system. The GigaWalk system uses two graphics pipelines with multiple processors, it was able to render CAD environments composed of tens of millions of polygons at interactive rates on an a SGI workstation [4]. Manta system employs a multi-threaded scalable parallel pipeline which takes advantage of a Itanium2 SGI supercomputer [5]. Therefore, the system was able to achieve a good rendering quality and interactive functions like transparency and clipping. More recently, voxel representations offered significant potential for massive model visualization [6–10]. The voxel based rendering method uses hierarchical voxel data to view-dependently represent the primitives in an approximate manner. Among them, Far-Voxels utilize cubical voxels to represent inner node of BSP tree [11], while R-LODs consists of a plane with material attributes [12]. More recently, VoxLOD uses a voxel with six shading attributes (colors and normals of six planes) to represent an inner Kd-tree node [13]. The voxels serve as a simplification of triangle primitives contained in a Kd-tree node. Although these studies have greatly improved rendering efficiency from many aspects, however, the rendering efficiency of large-scale CAD models on commodity PCs is still low, the refresh rates in investigated literatures are still low.
