graphics workstations have rendering performances of more than one million polygons per second in This paper presents a graphics workstation for real­ conjunction with hardware supported transparency, time display of Phong shaded polygons. The applied anti-aliasing, perspective texture mapping, image shading method is based on normal vector compositing, etc. In spite of the fact that great stri...

Rice is an important staple crop throughout the world, but environmental stress like low-light conditions can negatively impact crop yield and quality. Using pot experiments and field experiments, we studied the effects of shading on starch pasting viscosity and starch content with six rice varieties for three years, using the Rapid Visco Analyser to measure starch pasting viscosity. Shading at...

A divide-and-conquer strategy in shape from shading is proposed for recovering book surface on fully perspective condition. It is shown that unique shape can be recovered despite of more unknowns than shade images by dividing original implicit SFS problem into explicit ones. Using invariance of shading, a transformed shading equation and a recurrence relation is derived for depth recovery. Whol...

This paper examines several existing methods of static shading device design, and presents a new approach called SHADERADE. The approach is implemented as an eponymous tool based on Rhinoceros® and EnergyPlus, and offers flexible, novel techniques for assessing the thermal desirability of solar transmittance through any potential shading volume or surface. Using simulated sidelit offices locate...

In computer graphics, rendering is generally defined as “p rocess of generating an image from a model, by means of software programs.” Among many rendering styles, in this paper, we will particularly focus on Toon Shading. In brief, Toon Shading, also known as Cel Shading, is a simplest nonphotorealistic rendering technique to give mesh a cartoon look and the impression of hand drawn models in ...

In order to obtain models of complex virtual environments, there are many solutions that make use of image-based rendering techniques. When using a set of images to represent an element in space as a billboard, there are some problems related with the shading calculations, once these elements are just planes in space. This article presents a new approach for shading objects represented by image...

Shoot tip cuttings of Quercus phillyraeoides A. Gray ‘Emerald Sentinel’ (‘Emerald Sentinel’ oak), in a transitional growth stage between softwood and semi-hardwood, were collected from containerized plants growing under uniform fertility on June 4, 1998. Cuttings were treated with talc formulations of indolebutyric acid (IBA), ranging from 0 to 8000 ppm (0.8%), and placed under intermittent mis...

The effect of pre and post-anthesis shading (20% of incident radiation) on pericarp development, cotyledon cell number and seed growth dynamic of fruits from three positions in the capitulum (peripheral, mid and central) of two sunflower (Helianthus annuus L.) genotypes were studied at two locations. Both shading treatments reduced pericarp weight, fruit volume and total yield per plant. Plants...

The extraction of three-dimensional shape from shading is one of the most perceptually compelling, yet poorly understood, aspects of visual perception. In this paper, we report several new experiments on the manner in which the perception of shape from shading interacts with other visual processes such as perceptual grouping, preattentive search ("pop-out"), and motion perception. Our specific ...
