Patchwork Terrains
We present a radically new method for the management, multi-resolution representation and rendering of large terrain databases. Our method has two main benefits: it provides a Ck representation of terrain, with k depending on the type of base patches; and it supports efficient updates of the database as new data come in. We assume terrain data to come as a collection of regularly sampled overla...
متن کاملStreaming Terrains
Streaming computer graphics data is challenging because of the need to retrieve large triangle meshes before any display can begin. This paper proposes and analyzes the benefits of borrowing techniques from lossy image compression to implement a novel technique of progressive terrain rendering for streaming over a network. The goal of the work is to provide a qualityaware framework for 3-D rend...
متن کاملFacility Location on Terrains
Given a terrain defined as a piecewise-linear function with n triangles, and m point sites on it, we would like to identify the location on the terrain that minimizes the maximum distance to the sites. The distance is measured as the length of the Euclidean shortest path along the terrain. To simplify the problem somewhat, we extend the terrain to (the surface of) a polyhedron. To compute the o...
متن کاملRegion Intervisibility in Terrains
A polyhedral terrain is the graph of a continuous piecewise linear function defined over the triangles of a triangulation in the xy-plane. Two points on or above a terrain are visible to each other if the line-of-sight does not intersect the space below the terrain. In this paper, we look at three related visibility problems in terrains. Suppose we are given a terrain T with n triangles and two...
متن کاملIntervisibility on Terrains
Many interesting application problems on terrains involve visibility computations; for example, the search for optimal locations of observation points, line-of-sight communication problems, and the computation of hidden or scenic paths. The solution of such problems needs techniques to answer visibility queries on a terrain eeciently, and/or the development of data structures encoding the visib...
