3D Digital Human Modeling (1)
• Concepts
• Provision with digital processing functionalities for a
whole human body in 3D using all visual and functional
information about internal organs as well as external
human surface model and skeleton motion
• 3D modeling and animation technology for digital
information processing that can represent shapes,
properties, function, and motion for human bodies,
including internal organs
• Standardized 3D digital information necessary for
developing 3D medical and health care applications

3D Digital Human Modeling (2)
• Required technologies
• Shape modeling of internal and external whole bodies in
partial or whole forms using graphics technology
• Motion modeling of internal and external whole bodies
in partial or whole forms using graphics technology
• For all visual human models, functional properties
should be able to be defined and combined into shape
and motion modeling of a human model.
