Computer Cluster Distributed Path Tracing Rendering Method for Large 3D Scenes

Abstract

The invention relates to a computer cluster distributed path tracing and drawing method of a large-scale three-dimensional scene. The method is characterized in that a computer cluster A001 is adopted to achieve distributed path tracing and drawing of the large-scale three-dimensional scene, the computer cluster A001 is formed by connecting N<c> computer graphic workstations through a network switch, wherein one computer graphic workstation serves as a main control node A002, the other computer graphic workstations serve as drawing nodes. When a model is built, geometric objects in the to-be-drawn three-dimensional scene are divided, the three-dimensional scene model is divided into N<c>-1 parts, and geometric data corresponding to the geometric objects contained in every part can be completely loaded to the memory of the corresponding computer graphic workstation. By dividing the large-scale three-dimensional scene model into several parts, the different parts are loaded to different nodes of the computer cluster, and the computer cluster is adopted to draw the large-scale three-dimensional scene in a distributed mode.

Description

technical field [0001] The invention relates to a computer cluster distributed path tracking drawing method for a large three-dimensional scene, belonging to the technical field of three-dimensional scene drawing. Background technique [0002] Path tracing is a common 3D scene rendering technology, which is widely used in film and television production, 3D visualization, art design and other fields. "Computer Graphics: Principles and Practice, Third Edition" published by J. F. Hughes et al. in 2014 gives a detailed introduction to path tracking technology, which is referred to as stand-alone version path tracking technology in the present invention. When using path tracing to draw a 3D scene, it is necessary to load the entire 3D scene into the computer memory first, and then draw the 3D scene according to the path tracing process. For a large-scale 3D scene, which contains a huge amount of geometric data, the memory of an ordinary computer graphics workstation may not be a...

AI Technical Summary

Problems solved by technology

For large-scale 3D scenes, which contain a huge amount of geometric data, the memory of ordinary computer graphics workstations may not be able to accommodate the entire 3D scene model data

Small and medium-sized film and television production companies usually have a certain number of computer graphics workstations, but they may not have enough funds to purchase higher-end computer hardware equipment
