Optimization and Implementation of Unstructured Grid Volume Rendering Algorithm
Visibility sorting is one of the key techniques in volume rendering of unstructmed grids.The efficiency of sorting algorithm greatly affects the efficiency of volume rendering.Hardware-Assisted Visibility Sorting 1 (HAVS) is one of the most important volume rendering algorithms.This paper proposes an optimization algorithm of HAVS by keeping a sorted list which could decrease the comparing time in the fiagment-level sorting process of k-buffer.The range of k is also analyzed by experiments.The results of experiment show that the proposed optimization algorithm obviously improves the efficiency of HAVS.
