Virtual crowd motion simulation framework

Abstract

The invention relates to a virtual crowd motion simulation framework. The virtual crowd motion simulation framework comprises 1) a main control console part which comprises a display control sub part, a rendering management sub part, an environment management sub part, a crowd management sub part, a clock updating control sub part and the like and supplies various configurations required by normal running of a program and scheduling and management functions to the sub parts, 2) an environment expression part for organizing and managing environment information of an environment where a crowd is positioned and supporting inquiry and updating for the environment information, and 3) an individual simulation part which consists of a behavior generation layer, a behavior execution layer and a physical implementation layer and is used for simulating motion behaviors of a single individual in the crowd, wherein the behaviors of the individuals in the crowd are organically combined, so that the motion simulation of the crowd is implemented. The virtual crowd motion simulation framework is relatively high in generality, verisimilitude and flexibility and can simulate the virtual crowd motion under various scenes and influence of multiple environment factors.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a virtual crowd motion simulation framework. [0002] Background technique [0003] In the field of virtual reality, realistic group motion simulation can be used to simulate crowd flow in various places (such as large stadiums, subway stations, etc.) The development, evaluation and improvement of emergency plans for emergencies provide scientific and intuitive analysis tools: they can also be used to generate thousands of virtual herds or virtual legion movements, which can reduce film and television production costs and improve film and television works and game scenes. visual fidelity. Therefore, it has broad application prospects in virtual reality-related fields such as public security, architectural design evaluation, film and television production, and game entertainment. [0004] In real life, the movement of crowds is formed by the organic combination of individual m...
