Embodiment Construction

[0022] An embodiment of a radial basis function-based group motion control method of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, a group motion control method based on radial basis function includes the following steps:

[0024] (1) The user inputs the number of individuals of the group, individual attributes and global control parameters of the group, and generates the group animation required by the user in real time;

[0025] Treat each individual in the group as an object that obeys classical mechanics, and the group individuals are treated as particles, they have similar individual attributes, and the individual attributes of the group include the mass of the individual, the radius of the neighbor, the initial velocity, the maximum Velocity, maximum acceleration, radius of collision avoidance, field of view, maximum driving force, starting position and target position, where the ...

Abstract

The invention discloses a method for controlling group mobility, which is based on the RBF and includes the steps: firstly, a user inputs each parameter of the group to form real-time group animation which is in line with the requirements of the user; secondly, the user specifies a series of control points and sets the corresponding velocity amplitude thereof, which represents the guide velocity to which an individual in the group moving to the point needs obey; thirdly, a RBF interpolation method acts on scattered control points input by the user to form a vector field which represents the velocity of the individual in the group and is used as a guide component for the mobility of the individual in the group; and fourthly, the simulated process of the mobility of the group is divided into a plurality of step length according to discrete time, the guide motion component is looked up for each step length individual in the group to calculate the voluntary roaming motion of the individual, and the individual moves towards the position of next time step length under the combined action of the guide motion component and the voluntary motion component. The method adopts the velocity vector field as the main controllable factor for the motion, has the advantage of fast formation and supports real-time interactive amendment.

Description

technical field [0001] The invention relates to a computer simulation system for user interaction and real-time manipulation of large-scale crowd walking, in particular to a group motion control method based on a radial basis function. Background technique [0002] With the in-depth research of computer graphics and 3D animation technology, examples of using 3D special effects in film and television works have become common. However, the mighty group scenes in the film were not easy to produce: neither traditional shooting methods nor general key-frame animation techniques could be used. If you use the traditional shooting method, the camera angle of view and the tripod are the biggest limitations; and using the traditional key frame technology and character animation technology, not only the animator needs to pay a lot of labor, but also the uniqueness of individual movements required by group animation and The coordination of the group is not necessarily guaranteed. Ther...
