Title:
3D VIRTUAL SPACE-BASED CROWD BEHAVIOR SIMULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/120822
Kind Code:
A1
Abstract:
The present invention relates to a 3D virtual space-based crowd behavior simulation device comprising: a destination input unit that receives input, from a user, of a selection of one among a plurality of vertices constituting a stacked-type multi-story building model as a destination vertex; a destination affordance field generating unit for generating a destination affordance field corresponding to a vector field representing a slope of a scalar field according to a distance between an arbitrary vertex and the destination vertex when a heat transfer amount on the basis of a predetermined scalar-based heat transfer amount function is assigned to the plurality of vertices; a collision avoidance affordance field generating unit for, when a plurality of agents are disposed on a plane with normal vectors in different directions included in the multi-story building model, generating a collision avoidance affordance field for inducing collision avoidance according to a repulsive force acting on at least one agent adjacent to each other on the basis of the positions of the respective plurality of agents; and a simulation generating unit that generates a simulation image of a movement in which the plurality of agents move toward a predetermined destination inside the multi-story building model according to a steering force acting on the plurality of agents by a combination of the destination affordance field and the collision avoidance affordance field.
