Kinetic energy heat distribution map-based dynamic virtual human simulation method

Abstract

The invention discloses a kinetic energy heat distribution map-based dynamic virtual human simulation method. The method includes the following steps that: 1) movement capture data are acquired, the kinetic energy model of the movement process of a virtual human is constructed under Riemann geometric space on the basis of the physical properties of the virtual human, and the kinetic energy heat distribution map of the movement of the virtual human is drawn under the joint space of the virtual human according to the kinetic energy model; 2) the movement process is analyzed according to the kinetic energy heat distribution map, the movement process is segmented according to color changes in the map, and key control parameters and conversion time are extracted; and 3) a posture-based virtualhuman controller tracks key gestures in real time; and 4) compensation force calculation is carried out based on the kinetic energy changes of postures, and the real-time movement simulation of the virtual human can be dynamically controlled. With the kinetic energy heat distribution map-based dynamic virtual human simulation method of the invention adopted, the virtual human can be controlled effectively in real time to perform real-time interaction with a virtual environment, the robustness of an existing method to virtual environment interaction can be enhanced, and the physical simulationof the movement of the virtual human can be more realistic.

Description

technical field [0001] The invention belongs to the field of computer graphics, and specifically relates to a dynamic virtual human simulation method based on a kinetic energy thermal distribution map. Part of the technology includes motion capture data analysis, virtual proportional differential controller principle, and virtual compensation force calculation. Background technique [0002] In the virtual world, the movement of bipedal simulation virtual human has always been an important research direction in the field of computer graphics, and has a wide application prospect in the field of computer graphics software such as game development and film production. Traditional virtual human animation simulation uses motion capture equipment to collect and reproduce human animation. Its limitation is that it cannot interact with the virtual environment in real time and can only edit and splice the collected animation to complete animation reuse. The physics-based virtual human...
