3-D visualising method for virtual crowd motion

The invention relates to a three-dimensional visualization method for virtual crowd sports. It includes the following steps: analyzing the becoming virtual crowd, and founding modeling board model base and material base; capturing or generating by handcraft the need body sports data and storing it; composing the sports data; processing drawing preprocessing for modeling board model base and the sports data; inputting simple script data described crowd sports; generating virtual individual; driving it sports to generate dynamic virtual crowd; realize population playing up. The method has the advantages of high efficiency, common use, and low modeling cost, realizing real time vivid virtual crowd sports with 30000 peoples scale in common PC.
