In this paper we discuss the problem of determining a meeting point of a set of scattered robots R = {r1,r2,...,rs} in a weighted terrain P which has n> s triangular faces. Our algorithmic approach is to produce a discretization of P by producing a graph G = {V G,E G} which lies on the surface

topographic surface given as a digital terrain model (DTM) can be approximated with position-dependent approximation errors by a Triangulated Irregular Network (TIN), and how this TIN can be adapted to changes of the camera. Instead of using special data structures the main idea of the new approach

The paper presents calculation method for co-ordinate profiles on the surface, which is described by a shape function of the second degree. Algorithm of regressive function SPLINE has been used for adjustment of profile line. Function SPLINE determines, which analysed point belongs to interval

provided by upwind structures and topographic factors. Terrain surface roughness information is a critical spatial input to generate wind multipliers. It is generally the first spatial field to be evaluated, as it is utilised in both the generation of the terrain and topographic wind multiplier. Landsat

The key to real-time rendering of large-scale surfaces is to locally adapt surface geometric complexity to changing view parameters. Several schemes have been developed to address this problem of view-dependent level-of-detail control. Among these, the viewdependent progressive mesh (VDPM

This study highlights the impacts of the surface variability on Land-Atmosphere interactions using multi-scale atmospheric simulations with the Weather Research and Forecasting model capacities, coupled with NOAH land surface model and Kusaka et al. (2001) urban canopy model. The 30-m resolution

dynamically in real-time, minimizing the number of rendered polygons and allowing for smooth changes in resolution across areas of the surface. The algorithm has been implemented for approximating and rendering digital terrain models and other height fields, and consistently performs at interactive frame

Mountain View, California 9403 In standard fractal terrain models based on fractional d Brownian motion the statistical character of the surface is, by esign, the same everywhere. A new approach to the synthesis p of fractal terrain height fields is presented which, in contrast to revious
