Swarming in a virtual world: a PSO approach to virtual camera composition

Camera placement in 3D scenes is a relevant issue in most 3D graphics interactive application, such as videogames, data visualization, and virtual tours. Virtual Camera Composition (VCC) consists in automatically positioning a camera in a virtual world, such that the resulting image satisfies a set of visual cinematographic properties [1]. We propose a Particle Swarm algorithm to solve the problem, which exhibits superior performances w.r.t. other approaches. The algorithm has been tested on a set of image descriptions on a complex 3D model.
