数据分布型sort-first并行图形绘制系统的研究与实现

sort-first体系结构常用来构建高性能并行图形绘制系统，基于immediate-mode的数据集中型Sort-first系统，对网络带宽高度依赖，网络带宽和归属计算易成为系统瓶颈,提出了一个基于retain-mode的数据分布型并行绘制系统，工作原理是将几何数据分布于绘制结点，并利用帧间相似性动态调整绘制结点上的数据分布以适应视角的改变，有效地降低了数据分布所需的传输开销，系统利用Cell结构来控制并行粒度，实验结果显示能以相对较低的并行开销实现高分辨率显示和并行加速。

Research and Implementation of a Data Distributed Sort-First Parallel Rendering System

Sort-first architecture is often used to build high-performance parallel graphics rendering systems. Data-centralized sort-first systems based on immediate-mode deeply reply on network bandwidth, and thus bandwidth and belonging computing are likely to become system bottlenecks. An architecture of data distributed parallel rendering system based on retained-mode is presented. Geometry data is distributed to render nodes and adjusted between them when viewpoint is changed. Frame-to-frame coherence is efficiently utilized to lower overhead. Cell structure and a quick model space dividing algorithm are used to control parallel granularity. The experimental results show that high resolution display and parallel speedup can be achieved with relatively lower overhead.
