摘要：This paper proposes and defines four eXtensible 3-dimensional (X3D) nodes to render real-world characters such as human being and animals in 3D virtual environments, which conform to the X3D standard format for representing and rendering real-world characters in virtual spaces, aiming to make them available as an extension of the X3D core nodes. Several examples are implemented to evaluate the effectiveness of the pro- posed X3D nodes. Implemented results demonstrate the feasibility of the proposed X3D nodes as an extension of the X3D core components for rendering real characters in 3D virtual spaces.
