In this paper we present a first implementation of an MPEG-4 based solution for visualizing 3D graphics data on mobile phone. We analyze the player performances with respect to the decoding time and rendering frame-rate. More than only visualizing 3D data from MPEG-4 files, we extend the player for visualizing complex content such the one presented in games. The main idea consists in using a remote server for the game logic and to update the local 3D graphics scene by using standard commands. Thus, we demonstrate that by using a standard player (that in the near future can be natively built in the mobile device) it is possible to address in an optimized manner both visualization of 3D data and mobile games
