Research And Implementation Of Virtual Human Motion System In 3D Game

Accompanied with the development of computer graphics, virtual reality as well as some related field, the development of Game Industry has improved greatly. A virtual human who reflects the user's activity in a virtual world works as a participant in a virtual environment, which enhances his feeling in such virtual world. Accordingly, the technology of geometry modeling of virtual human, action generation and man-machine interaction become researching hot spots currently.In the light of the general framework of action control for virtual human and design method, this thesis focuses on the key technologies of action reality of virtual human. It mainly discusses modeling of virtual human, the technology of action control of virtual human as well as man- machine interaction, and it also researches systematically simulation training system for virtual human and path planning algorithm for virtual human in a virtual atmosphere. So, this thesis has the following works.To start with, according to the analysis of human skeleton and the study of modeling method for virtual human, we use patch schemes to solve the modeling problem of virtual human. Secondly, from the analysis of motion model when people running and walking, and from the study of action generation system of virtual human, we propose key method based on coordinate value. This method effectively solves the problem of unreal action. Finally, we systematically study simulation training system and path planning algorithm for virtual human in its virtual environment. We realize the man- machine control of virtual human in Three- dimensional Scene from adjusting direct 3D function. That means we have the capability of using key board, mouse, PS game port and other peripheral devices to control virtual human's walking direction and sighting direction.
