Abstract

The invention discloses a method for image synthesis in parallel rendering, comprising: performing experiments according to different image resolutions to obtain an optimal grouping (m, k) table; Perform optimal grouping; image synthesis is performed within a group through an m-ary tree; the final image is synthesized between groups through a BinaryTree method; the image synthesis mSwap method mentioned in the present invention optimizes and combines the existing image synthesis strategies. Some images and (m, k) tables group each node and find out the best processing situation of each node, make full use of the performance of each node, and improve the utilization rate of each node to a certain extent; The Binary Tree method is used to synthesize the final image, which avoids the process of image acquisition; the mSwap image synthesis strategy can not only reduce the communication cost, but also is more suitable for large-scale image synthesis.

Description

technical field [0001] The invention relates to a strategy for image synthesis in parallel rendering, in particular to a method for image synthesis in parallel rendering. Background technique [0002] With the continuous development of scientific research and engineering design, the scale of data is increasing. Therefore, how to quickly and accurately represent a large amount of data and realize the visualization of large-scale data poses a challenge to traditional rendering methods. Parallel rendering (ParallelRenderring) technology is a graphics rendering technology using a cluster environment system, and it is one of the methods that can effectively solve this challenge. Parallel rendering is to use multiple graphics rendering nodes or multiple graphics rendering pipelines to enable them to simultaneously exert their rendering capabilities to complete the rendering task under limited conditions. The graphics rendering pipeline usually consists of 2 stages: geometry proc...
