Abstract

Provided are a system and a method that automatically produce natural locomotion animation without an applicable discontinuity portion with respect to various moving distance and timing by using motion capture data. The system includes a motion capture data storage, a simulation calculator, and an animation calculator. The method includes defining a speed calculated in the moving motion capture data as a maximum moving speed of a simulation in order to calculate an entire moving distance, a stopped time when starting and arriving, and a stopped time before starting and after arriving regarding to respective characters; extracting a portion of the arriving motion capture data to be appropriate for the entire moving distance in order to produce the locomotion animation when the entire moving distance is less than a moving distance of the arriving motion capture data; and satisfying an entire time corresponding to an entire motion of animation.

Dependent claims

A locomotion animation producing system using motion capture data, comprising:

a motion capture data storage configured to store starting motion capture data in a starting stage, moving motion capture data in a moving stage, and arriving motion capture data in an arriving stage secured by dividing the motion capture data;
a simulation calculator configure to determine a speed calculated from the moving motion capture data as a maximum moving speed for a simulation and calculate an entire moving distance required for the simulation, a stopped time when starting and arriving, and a stopped time before starting and after arriving for each characters;
and
an animation calculator configured to extract a portion of the arriving motion capture data according to the entire moving distance if the entire moving distance is less than a moving distance of the arriving motion capture data and produce a locomotion animation using the extracted portion of the arriving motion capture data to satisfy an entire time corresponding to an entire motion of animation,
wherein the starting motion capture data include a first portion of the motion capture data corresponding to a period between that a corresponding character sufficiently stops and starts to move and that the movement is stabilized,
wherein the moving motion capture data include a second portion of the motion capture data corresponding to a period that the movement of the corresponding character is stabilized, and
wherein the arriving motion capture data include a third portion of the motion capture data during a period between that the corresponding character reduces its moving speed and that the corresponding character sufficiently stops.
