Wide area network-oriented decomposition support method for animation rendering task and implementation method

Abstract

The invention discloses a wide area network-oriented decomposition support method for an animation rendering task and an implementation method, which belong to the field of computer networks. According to the intensive computation characteristic of the animation rendering task and the characteristic that the transmission rate in a wide area network environment is limited to a network bottleneck bandwidth, the method comprises a visible range-based scene file and picture set splitting method, a node performance assessment method, an operation distribution strategy and integration and process control of the methods. During composition of the rendering task of a user, the scene file and picture set splitting method related to the invention is used and a scene is optimized according to the analysis of objects and pictures which are visible and invisible for the current scene camera, so that the aim of reducing a final rendering file is fulfilled. In a simplified model scene, a transmission data volume in a network can be effectively decreased, equivalent splitting of a scene file and a calculated amount is realized, and the distribution and execution of the fineness of rendering operation are facilitated. By using the method, the computing efficiency of each rendering client is brought into full play, and very high expandability is achieved.

Description

technical field [0001] The invention relates to a wide area network-oriented animation rendering task decomposition support method and implementation system, which is widely applicable to digital creation fields related to media production, such as three-dimensional film and television animation production, architectural design, etc., can significantly improve the efficiency of distributed animation rendering, and has a strong scalability. Through the method of splitting scene files and texture sets based on the visual domain, it solves the problem of a large amount of transmission data occupied by the transmission of 3DS Max scene files and textures in the wide area network environment during the rendering process, and realizes the rendering scene data volume and Equal-grained and fine-grained splitting of the amount of calculation; through real-time collection and rendering of the performance of client nodes, an optimized job decomposition and distribution scheme that matche...
