GTVIS: Fast and Efficient Rendering System for Real-Time Terrain Visualization

The paper presents an improved scheme for the visualization of 3D terrain in real-time using Digital Elevation Model (DEM). The method is primarily based on a modified version of Real-time Optimally Adapting Mesh (ROAM) that boosts performance by improving the rendering speed, enhancing the visual continuity and achieving frame rate constancy. We outline how to achieve better detail and continuity and yet maintain high speed. We have also integrated Geo-morphing technique to eliminate visual discontinuity due to the refinement of ROAM. Based on the proposed methodoly, Geo-morph Terrain VIsualization System (GTVIS) was crated. Experimental results confirm striking improvement in the rendering efficiency, frame rate constancy and visual continuity, while preserving important features of the terrain (such as sharp peaks and valleys).
