A Multiresolution viewpoint based Rendering for Large-scale point models

摘要：

In this paper, we present a non uniform partitioning point-octree data structure based on level-of-detail (LOD) to implement multiresolution rendering adaptively according to viewpoint Our approach generates a spatial partitioning hierarchy of irregular point samples in 3D space, and we provide a particular point-octree LOD generation algorithm. We also present a blending array e-zk-buffer to improve the rendering quality and remove the hidden surface. Our approach can choose specific level of detail and scheme to render according to viewpoint and feature of points to control the complexity, quality and speed of rendering.
