Rendering of Wet Materials

چکیده
The appearance of many natural materials is largely influenced by the environment in which they are situated. Capturing the effects of such environmental factors is essential for producing realistic synthetic images. In this work, we model the changes of appearance due to one such environmental factor, the presence of water or other liquids. Wet materials can look darker, brighter, or more specular depending on the type of material and the viewing conditions. These differences in appearance are caused by a combination of the presence of liquid on the surface and inside the material. To simulate both of these conditions we have developed an approach that combines a reflection model for surface water with subsurface scattering. We demonstrate our approach with a variety of example scenes, showcasing many characteristic appearances of wet materials.

Rendering of Complex Materials for Driving Simulators
The visual realism of a virtual scene is very important for driving simulators. In real life, a scene is composed of complex materials (asphalt, vegetation, road mark...) interacting with light sources (sun, headlamps...). Our goal is to simulate such environments in real time under various weather conditions (dry or wet road). The lighting interaction cannot be simulated directly using standar...
متن کاملSpatial Relationship between Mandibular Third Molars and Inferior Alveolar Nerve using a Volume Rendering Software
Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...
متن کاملUse Of Sednet Model To Establish Sediment Export Targets For Catchments Of The Wet Tropics Draining To The Great Barrier Reef
Some of the inshore reefs of the Great Barrier Reef are showing impacts consistent with a decline in water quality as a result of increased sediments and nutrients. The Wet Tropics covers approximately 2.2 million hectares and includes 91 percent of the Wet Tropics World Heritage area. The climate and geomorphologic conditions of the region are unique in Australia and generally result in fast f...
متن کاملReal-time Rendering of Wet Fur
Fur is present in most mammals which are common characters in both movies and video-games, and it is important to model and render fur both realistically and fast. In computer graphics, there are mainly two approaches to fur rendering. Using primitives such as lines or curves, and using textures containing sampled fur geometry. The former case is oriented towards realism and the latter case foc...
متن کاملDry and Wet Fake Fur Rendering
This work presents a probabilistic lighting model for rendering of thin fur of mammals under environmental influence, particularly water. We have extended the technique known as Fakefur by adding a method for capturing the key characteristics of fur influenced by water. The system described in this work has a lower computational cost than typical resolvable fur methods, due not only to its prob...
