Texture mapping has become indispensable in image synthesis as an inexpensive source of rich visual detail. Less obvious, but just as useful, is its ability to mask image errors due to inaccuracies in geometry or lighting. This ability can be used to substantially accelerate rendering by eliminating computations when the resulting errors will be perceptually insignificant. Our new method precom...

This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...

As part of sustainable architecture principles and practices, designers need to define building's architectural requirements based on climatic conditions, environmental preservation and reduction in energy consumption. The natural energy sources such as solar radiation affect thermal and lighting performances of buildings depending on its facade characteristics. Traditionally, buildings thermal...

Search by Object Model — finding an object inside a target image — is a desirable and yet difficult mechanism for querying multimedia data. An added difficulty is that objects can be photographed under different lighting conditions. While human vision has color constancy, an invariant processing, presumably, here we seek only covariant processing and look to recover such lighting change. Making...

This paper presents a pre-computation based method for real time global illumination of dynamic objects. Each frame of animation is rendered using spherical harmonics lighting basis functions. The pre-computed radiance transfer (PRT) associated with each object’s surface is unfolded to a rectangular light map. A sequence of light maps is compressed using a high dynamic range video compression t...

We present an interface for quick and intuitive development of arbitrary, but physically correct, Bi-directional Reflectance Distribution Functions, or BRDFs. Our interface, referred to as BRDF-Shop, provides artists the ability to create a BRDF through positioning and manipulating highlights on a spherical canvas. We develop a novel mapping between painted highlights and specular lobes of an e...

While many 3D scanning techniques can accurately record the geometry of sites and artifacts, a subject’s reflectance properties are often simplistically recorded as an RGB texture map. In reality, each point in a subject’s volume scatters incident illumination according to a complex 4D phase function unique to itself, yielding far richer reflectance behaviors than traditional texture acquisitio...

The ability to follow man-made paths and roads is an important capability for a number of robotic tasks. To operate in outdoor environments designed for humans, autonomous robots must identify footpaths, and drive along them. In this paper, we describe a computationally efficient approach to identifying and following footpaths, using only a single camera. Our technique takes the robot’s kinemat...
