چکیده
We describe several programs working with 1201x1201 gridded (array) terrain elevation data: determining the viewshed of an observer, and the visibility indices of all points, converting from a grid to a TIN, losslessly and lossily compressing a grid, and interpolating from contours to a grid. The intent is to integrate these, and new, programs, into a test suite the better to understand hypsography.

متن کاملT-spline surface design in engineering
T-spline surfaces are a powerful tool in geometric modelling. A T-spline surface is an approximation of a T-grid data structure. T-grids support adaption operations like local refinement or merging of existing NURBS grids. Digital terrain models based on T-spline surfaces benefit from non-regular control grids. We show some exemplary application cases for T-spline based terrain modelling.

متن کاملCoupling Terrain and Building Database Information for Ray-Tracing Applications
In this paper a methodology for the combination and integration into a single data base of terrain and building data is presented. This study is justified if ray-tracing techniques are to be used in propagation and channel modeling studies. Usually terrain is available in grid or elevation form while building information is normally facet-oriented. Ray-tracing (RT) techniques deal with flat fac...
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...
