基于粒子驱动的海洋仿真技术研究
Research on particle-driven ocean simulation technology
摘要
Abstract
In recent years,there has been a growing demand for realistic ocean scenes and wave effects in real-time applications,such as games and virtual reality.To address the large data transfer volume and the lack of smoothness in wave generation in existing wave particle algorithms,a new particle-driven ocean simu-lation algorithm is proposed:GeoWave Particle Algorithm.This algorithm initially generates environment particles to stimulate the environmental and geometric particles for interactive wave simulation,which are subsequently transmitted to the GPU for processing.In the geometry shader stage,a single geometric particle is split into numerous particles,effectively solving the issue related to large data transmission.Additionally,a Weighted Pixel Alignment algorithm is introduced to handle both types of particles,addressing the concern re-garding wave roughness.Experimental results demonstrate that the GeoWave Particle algorithm significantly improves rendering efficiency in complex scenes and provides smoother visual effects.关键词
