Research And Implement On The Description Language Of Virtual Human Action Based On VRML

With the development of the 3D technology, computer animation has widely applied in many areas such as biology, military affairs and network games etc. The virtual human as the most colorful factor in 3D animation world. Therefore, virtual human animation description language is a hot topic of current research. The contents included in the thesis are as follows:(1) The virtual human modeling in VRML. A virtual human modeling is completed according the H-Anim virtual human standard, which offers an entity for implementing the actions.(2) A description language of virtual human named IVHDL based on VRML is defined. It privodes the elementary actions and control arithmetic operators to allow the users to construct virtual human animation .(3) IVHDL language support for the prototype system is defined. IVHDL language support for the prototype system provides interactive and input text box in two ways to construct the virtual users who animation. Finally, the thesis through examples of virtual people walk introduce to IVHDL language to use and validation of the prototype system is correct and effective.
