D3DPR: a Direct3D9-Based Parallel Rendering System

According to the features of Direct3D9graphics library，D3DPR system architecture and implementation principle is presented. D3DPR is a parallel rendering system that supports transparent Direct3D9application parallelization and can be divided into two local node types，resource distribution node （D-node） and resource rendering node （R-node）.Through interception technique of DPGL parallel rendering library on D-node and reconstruction technique on R-node，any Direct3D9application can be converted for parallel rendering on PC clusters with no modification，and high-performance rendering and high-resolution tiled display can be achieved.As a result，this type of display can be used to generate better photorealistic and immersive virtual environments.
