Content based management of three dimensional data in the framework of the MPEG-7 standard is considered. An overview of MPEG-7 and three dimensional data is presented. Descriptors and description schemes suitable for three dimensional data are introduced and their integration in the framework of MPEG-7 is detailed. The shape descriptors are based on cords, wavelet transform and three dimensional statistical moments. Implications of the normative and the non-normative parts of the standard are analyzed and their relations are considered. The descriptors and description schemes are evaluated according to MPEG-7 criteria. Experimental results indicating the potential of the descriptors are presented. Some considerations on dynamic scenes are introduced
