Data parallel treatment based virtual reality 3D simulation method and system

Abstract

The invention discloses a data parallel treatment based virtual reality 3D simulation method and system. The method comprises the steps of: establishing a three-dimensional model and setting initial border conditions; performing domain decomposition on the three-dimensional model; inputting the initial border conditions and element information in each sub-model into a progress; regarding the initial border condition as a calculation condition, setting borders again when the initial border conditions in the calculation process change, calculating the sub-models again until the borders are steady or the calculation sub-results are constant numbers; combining the calculation sub-results and generating an integral calculation result of the model; setting a camera angle, a traveling path and a rendering effect and generating a 3D document based on the calculation result; playing and showing through a 3D player. The data parallel treatment based virtual reality 3D simulation method and system can be widely applied to the three-dimensional design industries, such as virtual operation, construction ventilation structure design and ventilation design. Through the results of the compute simulation and virtual reality technology, transient characteristics of a virtual object is shown stereoscopically, the exhibition degree is improved, and the design effect is enhanced.

Description

technical field [0001] The present invention relates to the technical field of computer simulation, and more specifically, to a virtual reality 3D simulation method and system based on data parallel processing. Background technique [0002] Existing numerical simulation results are mainly directly displayed on ordinary display devices through Tecplot, AVS and other commercial software; they cannot be connected with virtual reality display devices (such as digital helmets, stereoscopic displays, etc.), and numerical calculation results cannot be interactively displayed , and cannot provide a highly immersive three-dimensional display, the observer has a weak sense of presence, and the existing virtual reality technology is mainly used for complex operations (such as simulated driving, parts assembly) demonstration teaching, virtual experiments, etc.; strong display , but cannot achieve accurate, online, and real-time simulation of the physics and behavior of virtual entities,...
