Abstract

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.

Description

technical field

[0001] The invention relates to the field of virtual reality, in particular to a three-dimensional visualization method for virtual crowd movement. Background technique

[0002] The visualization of virtual crowd movement refers to displaying the movement data of the crowd on the screen. When the movement data is given to an individual, by observing the movement of the individual on the screen, one can understand the macro or micro effect of the movement data. The three-dimensional visualization of large-scale crowd movement can generate realistic virtual crowds in computer space, and observe the movement of crowds in various places and situations from all angles, which has a very broad application prospect. For example: in the design of large buildings (such as railway stations, stadiums, etc.), designers must consider the performance of large-scale crowds when various emergencies (such as fires, explosions, stampedes, etc.) Visualization technology can con...
