Texture_Based Volume Rendering Using Full Binary Tree Partitioning for Large Datasets
摘要
Abstract
In order to break through the limitation of GPU memory for the traditional texture_based volume rendering, an effective technique utilizing 3D texture partitioning based on full binary tree is presented for rendering large-scale volume datasets interactively on general purpose GPU . Using the Fragment Programming capability of commodity graphics cards, the texture data is transferred to a 1D color lookup table and a working set of dynamic texture datasets equivalent to the volume dataset size.The working set manages the boundaries between blocks with the help of abstract partitioning and inherited attributes. The experimental results show that this method is efficient for rendering large-scale volume datasets at an interactive rate on general purpose PCs.关键词
