Abstract

In this paper, we design a new blending array δ-zk-buffer to improve the rendering quality and remove the hidden surface. δ-zk-buffer is a three-dimensional array according to the region of drawing and numbers of blending Surfels. It is controlled by the tolerance δ and generated during rendering process. We also design blending rendering algrithm based on non uniform partitioning point-octree data structure to realizes the balance of drawing speed and drawing quality according to the distance of viewpoint position and models. Point-octree data structure can filter invisible points before the time-consuming process of rendering and can help to select different detail levels according to the view point position to control the complexity and speed of rendering.
