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 (...

this study aimed to determine the effects of different shading ratio and covers on “sultana seedless” table grape quality and storability. grapevines were covered at the veraison stage with 3 shading nets (0, 35, and 75% shading), which were then replaced with covering materials including polypropylene cross-stitch (pc), life pack (lp) and mogul (mg), just before harvest. harvested grapes in al...

We present a novel architecture for flexible control of shading rates in a GPU pipeline, and demonstrate substantially reduced shading costs for various applications. We decouple shading and visibility by restricting and quantizing shading rates to a finite set of screen-aligned grids, leading to simpler and fewer changes to the GPU pipeline compared to alternative approaches. Our architecture ...

In this paper, parametric design approach is used to optimize the external shading device design, which take examples of horizontal shading devices and horizontal louver shading devices on south faced of buildings in Guangzhou, Shanghai and Beijing. The optimize goal of whole year shading effect is “Shading in summer and solar in winter, both as much as possible at the same time”. In the first ...

Shading was used to generate the appearance of an obliquely illuminated surface with spherical indentations and protrusions. The "pop-out" of an apparent indentation among numerous apparent protrusions served as a psychophysical assay for shape-from-shading. Detectability of the pop-out varied with the direction of apparent illumination, a finding which is characteristic for shape-from-shading ...

The support for IEEE floating point computation and the exposure of shading functionality in a standardize API form have made graphics hardware a viable workflow solution to an artist involved in digital content creation (DCC). Nevertheless, there still remains a significant interface void between the abstract shading description an artist is used to and the low level shading constructs the har...

the interior pixel colors from the vertex colors. Phong . Gouraud shading and Phong shading are widely used interpolation methods to render a polygon mesh of a curved surface. When an illumination equation has a specular reflection term, Phong shading produces more realistic results than does Gouraud shading. The specular highlights produced by Phong shading give visual information about surfac...

Rendering systems often represent curved surfaces as a mesh of planar polygons that are shaded to restore a smooth appearance. Gouraud shading uses linear color interpolation and its hardware implementation is relatively easy, but it handles specular highlights incorrectly and introduces annoying artifacts called Mach banding over the edges of the polygon mesh. In software rendering Phong shadi...
