基于GPU加速的实时烟雾细节合成算法
Real-time smoke detail synthesis algorithm based on GPU acceleration
摘要
Abstract
To address the issues of insufficient detail and low real-time performance in smoke simulation,this paper proposes a GPU-accelerated parallel real-time smoke simulation algorithm based on detail synthesis.After solving the smoke control equations in parallel on a grid,the algorithm rapidly generates detailed veloc-ity fields by leveraging high-frequency energy fields and precomputed turbulence functions to achieve realistic smoke rendering with enriched details.To mitigate the impact of detailed velocity fields on the overall fluid morphology,a synthesis coefficient is introduced to adaptively adjust the intensity of synthesized turbulence.After updating the grid density data,the algorithm applies an optimized ray casting method for volume render-ing of smoke.The experimental results show that the proposed algorithm achieves rich detail representation while maintaining real-time performance,making it well-suited for applications such as game experience,battlefield simulation,simulation training.关键词
