A Hybrid, Hierarchical Data Structure for Real-Time Terrain Visualization
The approximation tree is a hybrid, hierarchical data structure for real-time terrain visualization which represents both geometry data and texture data of a terrain in a hierarchical manner. This framework can integrate different multiresolution modeling techniques operating on different types of data sets such as TINs, regular grids, and non-regular grids. An approximation tree recursively ag...
متن کاملDirect Volume Rendering of Stack-Based Terrains
Traditionally, the rendering of volumetric terrain data, as many other scientific 3D data, has been carried out performing direct volume rendering techniques on voxel-based representations. A main problem with this kind of representation is its large memory footprint. Several solutions have emerged in order to reduce the memory consumption and improve the rendering performance. An example of th...
متن کاملReal-time Terrain Rendering with Incremental Loading for Interactive Terrain Modelling
Real-time terrain rendering techniques usually employ static data structures and do not allow interactive modification of the terrain. In this paper we describe a real-time geometric clipmapping terrain rendering technique for large terrains which allows incremental updates of the underlying data structure. We have combined the method with an interactive sketch-based terrain modelling technique...
متن کاملFast Depth-Image Meshing and Warping
In this paper we present a novel and efficient depthimage warping technique based on a piece-wise linear approximation of the depth-image as a textured and simplified triangle mesh. We describe the application of a hierarchical triangulation method to generate triangulated depthmeshes efficiently from depth-images, discuss alternative depth-mesh segmentation methods to avoid occlusion artifacts...
متن کاملAdaptive Level of Detail for Large Terrain Visualization
This paper presents a sophisticated tile-based terrain rendering system for large-area terrain visualization. The developed system employs quadtree algorithm to create multiple levels of details (LOD) of terrain tiles. The visualization determines visible tiles by view frustum culling and renders the scene efficiently. A key issue in quadtree-based LOD generation is the thresholding for differe...
