Abstract


In the field of computer graphics research cluster parallel rendering is one of the important technology to achieve high - resolution real-time rendering of large - scale complex scenes . Computer cluster , constituted by the the cheap high cost PCs rely on high-speed Gigabit LAN interconnection together to complete large - scale graphics computing parallel rendering tasks . And commercial high - speed graphics workstation or mainframe parallel high-performance computing solutions , low cost advantage , but also good compatibility and scalability advantages . Thesis cluster parallel rendering system technical issues discussed , analyzed some of the inadequacies of conventional parallel rendering system , the architecture and design of a hybrid system , and the system core control algorithm has made ??innovative and exploratory research . The main contents are : depth study of the DirectX standard graphics pipeline technology , programmable the octree scene graph lines and large scene to render the scene accelerated algorithm used in the spatial data structure : and learning Ogre, Irrlicht open source 3D engine designed and implemented a system for parallel rendering engine . Study TCP / UDP protocol windows socket method of network programming , system communication architecture , complete system application layer data communication design , including application layer communication package design and the analytic method . . Commonly used parallel rendering system architecture and its balancing algorithms , given the design of the overall system module as well as the parallel architecture , the balancing algorithm absorption screen grid load thinking , new ideas . Parallel rendering system task allocation using screen squares correlation algorithm performance boost . First, the system searches for the projection space screen load intensive areas ; then the depth direction of the load balancing algorithm in pixel -intensive areas , other regional implementation screen load bisection algorithm ; Finally , the analysis of the core algorithm performance parallel rendering system and balance the impact factor , given a simple and effective feedback method .
