Multi-stream Based Rendering Resource Interception and Reconstruction in D3DPR for High-Resolution Display

In order to bring Direct3D9 application to run on PC clusters for high-resolution display with no modification, we have firstly presented D3DPR parallel rendering system. According to multi-stream scene data organization and storage mode of Direct3D9, rendering resource has been classified as command stream, vertex stream, index stream and texture stream in D3DPR and the rendering resource interception and reconstruction becomes the most crucial problem. In this paper, above all we give an overview of D3DPR system architecture. Subsequently we bring forward multi-stream based rendering resource interception in D3DPR. In this section, we design DPGL, i.e. Direct3D9-based Parallel Graphics Library, through which the rendering information of Direct3D9 application can be converted into the above described rendering resource. Finally we focus on multi-stream based rendering resource reconstruction in D3DPR, through which the rendering command and scene data was reconstructed.
