Abstract

In this paper, adaptation of 3D graphics on the basis of the MPEG-21 DIA (Digital Item Adaptation) standard is presented. The MPEG-21 DIA standard covers a general usage environment description framework for adapting multimedia contents including computer graphics. The adaptation parameters for the 3D graphics consist of user characteristics and terminal capability. The user characteristics parameters represent the user's quality preferences on graphics components of geometry, material and animation as well as 3D to 2D conversion preference. The terminal capability parameters represent the graphics format and the graphics processing capacity of vertex processing rate, fill rate and memory bandwidth. MPEG-21 3D graphics DIA adaptation system adapts 3D graphics to these usage environment parameters input from the user for the best experience of the graphics contents.
