A Mobile Graphics System for Ubiquitous Environment

We describe an intuitive computer graphics creation environment usable on tiny mobile devices. We adopted a 3D modeling method based on interactive genetic algorithm (iGA). It allows users to intuitively produce high quality graphics contents on site by evolving a set of 3D models. The proposed system enables the users to easily design 3D graphics contents by using a mobile device anywhere at any time without sacrificing visual quality. The computing power of the mobile devices is not enough for visualizing realistic 3D objects. We therefore employed client/server architecture for balancing computing loads between a server and a mobile client. The client plays a role for handling user interactions and 3D contents visualization whereas the server is responsible for all heavy computations such as 3D graphics modeling, rendering, and evolutionary processing by iGA. Providing good user interface is a crucial factor for mobile software design. We prototyped multiple GUI layouts and conducted a comparative experiment to figure out a good design approach for mobile 3D graphics system.
