一种基于分布式渲染的分屏实现方法

Implementation of Screen Division in Distributed Rendering

分屏技术是高分辨率、超大屏幕的分布式渲染的实现基础。本文对分屏的技术原理进行了分析和研究,并提出一种基于Ogre渲染引擎的分屏实现方法。即根据不同的分屏要求,修改投影变换过程中的四阶透视投影矩阵,沿Camera射线方向切分原场景中的视屏截头体。

Screen division is one of basic technologies for distributed rendering system with high resolution and multi -screens. In this paper, we do some research on the theory of screen division, and present a method to implement screen division based on Ogre. which modifies four - dimensional projection matrix during the process of projective transfer and cuts view frustum into sub - parts from camera direction according to the desire of screen division.
