Introduction

This chapter deals mainly with the basics. Questions to be answered are: what are digital terrain models, what is necessary in order to create accomplished landscape visualizations, who creates and who needs digital terrain models, and in which fields are digital terrain models used?

Palabras clave: Digital Elevation Model; Civil Engineering; Digital Terrain Model; Landscape Model; Digital Surface Model.

Pp. 1-11

doi: 10.1007/978-3-540-30491-3_2

Fundamentals and Data Source

A short overview of the historical development of landscape visualization, and a few facts about the sources of data.

Palabras clave: Digital Elevation Model; Contour Line; Delaunay Triangulation; Digital Terrain Model; Universal Transverse Mercator.

Pp. 13-40

doi: 10.1007/978-3-540-30491-3_3

3D Visualization of Terrain Data

This chapter focuses on five main topics. These are the import of existing geo-data, the creative modeling, some information concerning materials, a few words about distortions and their animation.

Palabras clave: Digital Terrain Model; Vertex Color; Virtual Reality Modeling Language; Terrain Data; Blend Material.

Pp. 41-88

doi: 10.1007/978-3-540-30491-3_4

Using the Camera

This chapter deals with the use of the digital camera. Special attention is given to using the camera as a tool for designing, and to handling the camera for walkthroughs and for special effects.

Palabras clave: Focal Length; Motion Blur; Virtual Camera; Lens Effect; Camera Path.

Pp. 89-121

doi: 10.1007/978-3-540-30491-3_5

Lighting

Where there is no light, there is no shadow.... And shadows are absolutely essential for a successful visualization ..

Palabras clave: Point Light; Global Illumination; Soft Shadow; Parallel Light; Local Illumination.

Pp. 123-150

doi: 10.1007/978-3-540-30491-3_6

Vegetation

Vegetation can dominate a landscape, as it is the first thing to meet the eye. For the designer of convincing 3D scenes, plants are the first encounter with the challenge of visualizing natural phenomena.

Palabras clave: Particle System; Picture Format; Plane Representation; Transparency Information; Grassy Area.

Pp. 151-187

doi: 10.1007/978-3-540-30491-3_7

Atmosphere

The term atmosphere is derived from the Greek words ατμός, atmós = air, pressure, vapour, and σϕαίρα, sfära = sphere. The atmosphere is the gaseous shell enveloping the earth. It consists of a mixture of different gases which are attracted by the gravitational field of our planet.

Palabras clave: Particle System; Cloud Formation; Blend Material; Color Richness; Gaseous Shell.

Pp. 189-218

doi: 10.1007/978-3-540-30491-3_8

Water

Out of the rain and into the gutter^1. While rain is a phenomenon belonging to the atmospheric effects, the effect of the gutter (or eaves) undoubtedly belongs to the field of animated water. There was a time when there were no gutters. At this time, during a heavy rain shower, nothing worse could happen to a person than to move out of the rain and under that part of the roof where the water that had first hit the roof came down like a torrent. The present chapter will deal, among others, with this subject. The main topic is water and the interesting forms in which it occurs in landscape visualizations.

Palabras clave: Particle System; Motion Blur; Global Illumination; Landscape Architecture; Open Water Surface.

Pp. 219-254

doi: 10.1007/978-3-540-30491-3_9

Rendering & Post Processing

Where is the “ender cool picture” button?

Palabras clave: Gray Scale; Post Processing; Picture Format; Joint Photographic Expert Group; Lossless Compression.

Pp. 255-284

doi: 10.1007/978-3-540-30491-3_10

Interaction with 3D Data

A short overview of the options for interaction with digital terrain models and landscapes.

Palabras clave: Workable Mesh; Digital Terrain Model; Geometrical Data; Joint Photographic Expert Group; Triangulate Irregular Network.

Pp. 285-309
