Abstract

The invention discloses a virtual footprint generation method, device and equipment, relates to the technical field of three-dimensional animation production, and can automatically calculate the moment when a foot steps on the ground according to the animation action of an object model and the real-time distance between the foot and the ground so as to accurately and quickly generate a virtual footprint. The method comprises the following steps: acquiring a fluctuation curve formed by a distance value between an object foot and the ground along with time information change; determining the time information corresponding to the trough position between any two adjacent wave crests in the fluctuation curve as the treading moment of the virtual footprint; creating a virtual footprint special effect at the treading moment, and generating a virtual footprint.

Description

technical field [0001] The present application relates to the technical field of three-dimensional animation production, in particular to a method, device and equipment for generating virtual footprints. Background technique [0002] In today's game and animation industry, in order to truly restore the motion effects of objects in games and animation scenes, virtual footprints are generated during the movement of objects to improve the quality and realism of games and animations. [0003] In related technologies, there are mainly two ways to generate virtual footprints. One is to use tools to create special effects animations of virtual footprints, and then bind the virtual footprints to the feet of the object model. The virtual footprint of the special effects animation, when the task turns, generates a virtual footprint that rotates the direction of the animation, so that the virtual footprint is always consistent with the direction of motion. However, for complex terrain...
