Further Information

This paper presents an efficient technique for real-time non-photorealistic three-dimensional terrain visualisation from the digital elevation model. The method is primarily based on an improved version of the Real-time Optimally Adapting Mesh (ROAM) that boosts performance by improving the rendering speed, enhancing the visual continuity and reducing large frame rate variances. We outline how to achieve better detail and continuity and yet maintain the high efficiency and speed of the visualisation. We also integrate a Geo-morphing technique to eliminate visual discontinuity due to the refinement of ROAM. Based on the proposed methodology, the Geo-morph terrain visualisation system was created. Experimental results confirm striking improvement in the rendering efficiency and visual continuity, while preserving important features of the terrain (such as sharp peaks and valleys).
