The increase in ease of the production of computer simulated graphics has opened new opportunities in the 3D industry. There are unlimited applications for the delivery of 3D Graphics especially concerning 3D multimedia presentation of digital content. Apart from aesthetic and entertaining reasons, experts apply computer simulations to visualize environments and to identify early errors or costs in order to limit the need of making real prototypes. Thus, 3D Graphics also minimize the time required for developing the final product. Existing 3D applications give partial support to users to engage in collaborative contribution for the production of a 3D model. However, when 3D artists are required to collaboratively produce a high quality 3D model based on thousands of polygons, they have to integrate the different parts of the model when the modelling process has been completed, which is a slow tedious process. This paper investigates how to dynamically and simultaneously apply changes to the same 3D model based on a collaborative network exploiting a Grid infrastructure.
