Designing Architecture in Practice of the 3D Engine for Geo-Browser

In order to solve the problem of 3D rendering for Geo-Brower terminal, by analyzing of existed engine and 3D engine, adapting method of Attribute Driven Design, this paper proposed the preliminary ideas of the 3D engine, which is able to build a preliminary technical framework system for Geo-Browser. Detailed analysis and design have been carried out for the architecture. As one of the theoretical system for Geo-Browser that provides three-dimensional rendering technology, the G3DEngine makes three-dimensional rendering in Geo-Browser terminal possible. The G3D engine not only offers a solution of 3D model loading and rendering for Geo-Browser, but also offers references for other engine designs.
