Human motion simulation method under fluid environment

Abstract

The invention provides a human motion simulation method under a fluid environment. The human motion simulation method under the fluid environment is based on real physical simulation and achieves interaction between a human body and fluid. A coupling surface interaction technology, a sub-chain movement velocity calculation technology, a target path calculation technology and a target path tracking technology are invented based on human body modeling. In a local simulation stage, a human body model is built based on Lagrange dynamics, and human independence movement states can be simulated well. In an interactive simulation stage, a coupling surface transmission method based on a sampling array improves interaction efficiency, and a velocity calculation method based on viscous resistance achieves smooth and steady interaction velocity change and lifelike interaction velocity change effects. In an overall simulation stage, a target path obtained based on a three dimensional A star algorithm meets movement characteristics of the human body in the fluid and has continuity, and a state selection algorithm based on a visual space enables the human body to track the target path well, and obtains a plurality of optional move states.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and in particular relates to a human body motion simulation method in a fluid environment. Background technique [0002] Human motion animation belongs to character animation, which has always been one of the hotspots in the research of virtual reality technology. It comprehensively uses the knowledge of computer science, art, mathematics, physics and other related subjects to generate colorful, continuous and real virtual pictures on the computer, providing people with a new world to fully display their personal imagination and artistic talent. . Human motion animation uses joint skeletons to represent the body structure of humans or other skeleton animals, and interacts with the surrounding scenes during the motion process, which is the most important idea in human motion technology. Although computer animation plays an increasingly important role in many fields, many problems are sti...

Problems solved by technology

[0004] Although a certain degree of interaction can be achieved by using existing technologies, human motion animation under the action of complex scenes based on real physics is rarely studied, which is due to the limitations of its own complex dynamic model and computer hardware and software conditions.
