There are many kinds of façade shading designs which provide optimal indoor daylighting conditions. Thus, considering combinations of different types of façade shading systems is an essential aspect in the optimization of daylighting in the building design process. This study explores (1) how the pattern and different characteristics are evaluated by varying façade shading types and considering...

This paper describes a new architecture for generating smoothly shaded two dimensional images of volume data. This architecture ts into an image synthesis pipeline and uses only simple arithmetic operations and a look-up table to generate two dimensional images in real time. The shading algorithm is an extension of the grey-level gradient algorithm for shading volume data. The shading technique...

Computer image generation systems often represent curved surfaces as a mesh of planar polygons that are shaded to restore a smooth appearance. In software rendering Phong shading has been one of the most successful algorithms, because it can realistically handle specular materials. Since it requires the rendering equation to be evaluated for each pixel, its hardware support poses problems. This...

It is a well-documented fact that partial shading of a photovoltaic array reduces it output power capability. However, the relative amount of such degradation in energy production cannot be determined in a straight forward manner, as it is often not proportional to the shaded area. This paper clarifies the mechanism of partial PV shading on a number of PV cells connected in series and/or parall...

In this paper, we introduce a new framework for the illustrative visualization of medical surface data. In most visualization frameworks, only light intensity is used to determine the surface shading. The analysis of medical textbooks reveals more complex shading approaches. The parameters of these approaches are mapped to different Shading Maps, which may be weighted and flexibly combined. We ...

in order to study the effects of shading on head and its near leaves on yield and yield components of spring safflower genotypes, an experiment was conducted in factorial arrangement based on a complete randomized block design with four replications at agricultural research station, faculty of agriculture, birjand university during 2008. factors were including three spring safflower genotypes (...

A design method has been developed by which the accessibility of light on PV cells in an arbitrary geometry can be quickly visualized and quantified. Modelling of irradiance in this method is based on ambient occlusion, which indicates the likelihood of shading of object’s surfaces due to self-shading or due to surrounding objects. The design method can be easily implemented in 3D modelling sof...
