图灵讲坛（第38期）：Acquisition of Natural Phenomena from Video
Acquisition of Natural Phenomena from Video
Prof. Peter Hall
英国巴斯大学 University of Bath, UK
Artists in the films and games industry often want to make models of natural phenomena such as tree, water, smoke, fire. This is no easy task: the models are often designed by engineers and are physically based, which makes them hard for artists to use; artists sometimes want the models to behave non-physically, which gives the engineers problems in designing an underlying model; the process is difficult and time consuming and so is expensive. This talk describes how to acquire three-dimensional, dynamic models of complex natural phenomena from a single consumer level video camera. The default output looks natural but is easy to edit to behave in the way artists want. We will discuss trees, water, and steps towards a solution for more general phenomena.
