The goal of the research is creation of an adaptation mechanism for the delivery of three-dimensional content. The adaptation of content, for various network and terminal capabilities - as well as for different user preferences, is a key feature that needs to be investigated. Current state-of-the art research of the adaptation shows promising results for specific purpose and limited types of content but still it is not well adoptable for the massive heterogeneous environments. In this research, we present a method for transmitting adapted thee-dimensional contents to multiple target devices. This paper presents some theoretical and practical methods for adapting three-dimensional contents, which includes shapes and animation. We also discuss practical details to the integration of our methods into MPEG-21 and MPEG-4 architectures.
