Spherical imaging is a technical approach of collecting scenery by viewing it through a single perspective. A typical realization of spherical imaging is a panoramic mosaic covering a part of the hemisphere. According to a photogrammetric definition, we introduce here, spherical imaging is an exact central projection explicitly determined by its projection center. They are linear images without...

This study explores the importance of different motivations to visit three types of recreational settings--farms, private forests, and state or national parks. Data were collected via a mail-back questionnaire administered to a stratified random sample of households in Missouri (USA). Descriptive and inferential statistics reveal both similarities and discontinuities in motivations for visiting...

Nowadays there are a wide range of techniques for terrain generation, but are focused on providing realistic terrains often neglecting the aesthetic appeal. The Genetic Terrain Programming technique, based on evolutionary design with Genetic Programming, allows designers to evolve terrains according to their aesthetic feelings or desired features. This technique evolves TPs (Terrain Programmes)...

This paper presents the experimental design and subsequent findings from a series of experiments in a large boundary layer wind tunnel to investigate the variation of surface pressures with increasing upwind terrain roughness on low-rise buildings. Geometrically scaled models of the Wind Engineering Research Field Laboratory experimental building were subjected to a wide range of turbulent boun...

This paper explores research in progress on Swarm Intelligence related to Procedural Terrain Generation. Our aim is to develop means to provide useful and real-time terrain deformation using Swarm algorithms. We feel this could prove interesting for enhancing the experience of gameplay in some game genres such as Real Time Strategy (RTS), simulation or even platform games.

Finding a scenic route between two locations is a common trip planning task, in particular for tourists and recreational travelers. For the automated computation of a scenic route in a trip planning system it is necessary to identify which attributes of a route and its surroundings are associated with attractive scenery. This study uses a route choice model, more specifically a Path Size Logit ...

With advances in image display technology, recapturing good-quality images from highfidelity artificial scenery on a LCD screen becomes possible. Forgers can recapture the artificially generated scenery and use the recaptured image to fool image forensic system. Image recapture detection is to distinguish real-scene images from the recaptured ones. An image recapture detection method based on m...

Visual simulation of natural scenery using computer graphics is an interesting research field with wide applications such as flight simulation and special effects in movies. There have been many studies of fractal techniques that use 1/f noise generated by FFT or the midpoint displacement method as modelling methods for imaginary mountain scenery. These methods are suitable for creating impress...
