Abstract

The invention provides a three-dimensional scene generation method based on OSG three-dimensional rendering engine preprocessing and a device thereof. A three-dimensional scene rendering model list and state parameters are customized; a three-dimensional engine basic object is initialized; multiple models requiring rendering are loaded, preprocessing post-processing rendering states of different models are set according to the predefined parameters, and the association relation between a physical engine and the models is established; and a series of preprocessing flows of displaying a three-dimensional scene are updated so that the problems of complex rendering hierarchy, realistic rendering and real and rapid physical collision loading of the three-dimensional scene can be solved, time of association with the physical engine can be shortened, the rendering effect and rendering efficiency of the scene and the models can be enhanced and the means of artificial control of the rendering flows can be enriched.

Description

technical field [0001] The invention relates to the field of three-dimensional virtual simulation, in particular to a method and device for generating a three-dimensional scene based on OSG three-dimensional rendering engine preprocessing. Background technique [0002] In 3D virtual simulation technology, the 3D rendering engine provides a series of operation interfaces for the realization of the structural principle and drawing of 3D scene graphics, including the model loading interface, 3D space and the assembly, rendering, optimization and control functions of the realization model. The 3D rendering engine adopts the rendering pipeline method in the rendering process, which is similar to the engineering assembly line. [0003] OSG (OpenSceneGraph) is a high-performance open source 3D graphics engine released free of charge based on the modified LGPL protocol. It is widely used in the fields of flight simulation, games, virtual reality, and scientific computing visualizati...
