Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as figure 1 As shown, the user-planned virtual crowd simulation framework of the present invention consists of four parts, including: group 1, trigger 2, motion range limiter 3 and cloud control terminal 4.

[0045] Group 1 specifies the number of individuals in the group, formation, behavior, activity range, group leader and other characteristics; the position of each group is determined by the centroid method, and the behavior of each member in the group is determined by the group leader and the interaction between members and the environment. It specifically includes four sub-parts: personnel composition module 11 , activity scope module 12 , target module 13 , and individual behavior and group behavior generation and execution module 14 .

[0046] Among them, the personnel composition module 11 defines the number of i...

Abstract

The invention discloses a user-oriented planned virtual crowd simulation framework. The user-oriented planned virtual crowd simulation framework comprises a group, triggers, a motion range limiter and a cloud control end. The group is defined and described by a staff composition module, an activity range module, an objective module and an individual behavior and group behavior module and used for simulation of group behaviors so that simulation of various complex group behaviors is achieved. The triggers comprise the path point trigger, the flow trigger, the time trigger, the speed trigger and other triggers and are used for planning crowd paths and determining path topological information and perceptual information of crowd behaviors. The activity range limiter is used for providing position information of static barriers in the environment. The cloud control end is used for planning optimal paths without congestion for crowds according to the path topological information specified by users and the objective of the group. The user-oriented planned virtual crowd simulation framework has good verisimilitude and real-time performance, high flexibility and convenient and fast operability and can simulate verisimilar virtual crowd behaviors on various scenes according to intentions of the users.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a virtual crowd simulation framework. Background technique [0002] With the rapid improvement of the computing speed of graphics hardware and the continuous improvement of virtual reality technology, people are no longer satisfied with only simulating visual information such as buildings and landscapes. is a simulation of a human subject. Based on this demand, virtual crowd simulation technology came into being. Virtual crowd simulation technology can provide auxiliary analysis and demonstration tools for crowd movement, and has broad application prospects in the fields of safety science, sports simulation, film and television animation, military training, ancient heritage reconstruction, etc. It is a research hotspot and has attracted the attention of many scholars. [0003] Research on virtual crowd simulation involves robotics, physics, computer graphics, computer animation,...
