3D Visualization on mobile devices

Abstract

This paper discusses current status and recent advancements of 3D graphics on mobile platforms and describes open issues concerning its usage in different applications. We have treated two particular application fields. Firstly, we deal with problems of visualization of complex data structures on mobile devices. The implementation of a 3D visualization renderer on the Symbian platform for mobile devices is written as a C++ application and based on the DieselEngine R 1 as a rendering engine. 3D visualization of data is generated in the form of a Virtual Reality Modelling Language (VRML) file meaning that actually any kind of 3D content written in VRML file format can be rendered on such a device. It was the result of a project the objective of which was to provide a user interface on a mobile platform displaying visualization of hierarchical Grid monitoring data. Secondly, we describe the system that brings face animation to embedded platforms. Face animation is considered to be one of the toughest tasks in computer animation today and its delivery to mobile platforms brings possibilities for development of new innovative and attractive services for the mobile market.

“…However, recent small electronic equipments such as mobile phones possessing enough CPU power offer these talking head interfaces as well. Rendering 3D graphics on mobile devices is a very complex task because of the vast computational power required to achieve a usable performance [5]. There are two particular challenges when the platform is a mobile device [6]: (i) limited computational power, and (ii) restrictions on input modalities such as low resolution and size of the device.…”
