Proximity Queries for Crowd Simulation Using Truncated Voronoi Diagrams

Abstract: Crowd simulation has been used in the entertainment industry to create populated environments that seem more realistic than isolated scenes, specially in urban areas. Video games are no exception, but the simulation of large crowds is often restrained by the remaining compute time available in CPUs, which is often used for most part of the game loop. This paper presents a parallel technique, using consumer grade graphics hardware, for proximity queries that is suitable for real-time crowd simulations. We use a… Show more

“…Hoff et al [11] presenta una técnica de detección de colisiones geométrica, rasterizando imágenes y tratando pixeles sobre-escritos como colisiones. De Gyves et al [4] presenta una técnica basada en diagramas de Voronoi truncado para realizar búsquedas de proximidad de manera eficiente en el GPU. Esta técnica es capaz de superar en desempeño a otras similares, resultando en simulaciones con miles de agentes en tiempo real, utilizando hardware de nivel consumidor.…”

“…Octrees). Other structures include the Voronoi diagram, which can be used to limit the search area and accelerate neighbourhood detection using GPUs [4,22]. Beyond identifying neighbours, centroidal particle dynamics can also utilize Voronoi diagrams to compute each entity's response to violations of its personal space [11].…”
