Abstract

This paper focuses on 3D data structures supporting an alternative approach for creating 2D vario-scale maps. The smooth animated zooming functionality have lead us to investigate a volumetric representation of gradually changing vario-scale objects. In this paper, the principle of vario-scale maps with theoretical knowledge about 3D representation (2D space plus 1D scale) is briefly introduced, followed by a description of our initial implementation efforts for creating a development environment for our research, which is based on the conversion from the classic tGAP data structure through tetrahedralization to a volumetric representation. The current results and examples of this volumetric representation with real world data and plans for future improvements are presented.
