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.

AI Technical Summary

Problems solved by technology

[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 and other links; strong display , but cannot achieve accurate, online, real-time simulation of the physics and behavior of virtual entities, so the effect of human-computer interaction is poor

[0003] The computing simulation system and virtual reality system based on the above-mentioned existing technologies cannot bring a real sense of presence to the sensor, nor can it achieve real real-time interaction. During some transient operations, such as an intern practicing vascular placement When performing surgical operations, the real-time interaction is poor when using the existing method, and it is difficult for the operator to accurately grasp the real-time situation

Because every action of the operator will affect the blood flow, unrealistic simulation cannot provide correct system feedback information for the operator, which may cause inestimable medical accidents in later clinical operations
