基于改进流体渲染管线的矢量场火灾模拟研究OA

In computer simulations of fires,the complexity of physical models and the low computational ef-ficiency led to an imbalance between realism and real-time performance.To reduce memory consumption during the fire spread process without compromising rendering realism,an improved rendering pipeline combining vec-tor field analysis and fluid dynamics solving methods is proposed.Firstly,a simulation pipeline for velocity and density sources is constructed within the fluid rendering pipeline,achieving the full process of fire spread and combustion changes through physical simulations.Secondly,volumetric rendering technology is introduced into the rendering pipeline,utilizing ray marching to enhance the visual realism of fire rendering.Finally,GPU paral-lel computation is employed to solve fire parameters,ensuring real-time simulation.Experimental results show that this model,combining physical simulation and fluid rendering advantages,offers better coupling compared to single physical simulations.It reduces memory consumption while maintaining high visual quality and improves real-time rendering efficiency.The model aligns with real-world physical laws and is suitable for interactive fire drills,enhancing people's understanding of fires.
