This paper proposes a new configuration for solar energy conversion systems. One challenging issue of the photovoltaic (PV) systems is partial shading, and in this paper Module Integrated Converters (MIC) are used to overcome this problem in PV arrays. A few boost converters are employed as MICs to mitigate the shading effect. Furthermore, to reduce the cost and to increase the system performan...

Nowadays, hardware support for Gouraud shading is state-of-the-art. Most hardware implementations of the Phong shading algorithm lack flexibility, for example are restricted in the number of light sources. In this paper, we will present a concept of shading processors that has been developed in a rendering system called PROOF. Two types of processors have been designed, one performing the norma...

This thesis focuses on the interaction between light sources and materials which is often called shading. It describes the design of the shading system implemented for the second version of the Turtle renderer that supports the flexibility and power of the Maya rendering packages shaders. It discusses different approaches to shading, how rendering of passes can be incorporated, multi threading ...

In this part of the course we will review some examples of shading algorithms that we might want to implement in a real-time or interactive system. This will help us to identify common approaches for real-time shading systems and to acquire information about feature sets required for this kind of system. The shading algorithms we will look at fall into three categories: realistic materials for ...

Diffuse interreflections mean that surface shading and shape are related in ways that are difficult to untangle; in particular, distant and invisible surfaces may affect the shading field that one sees. The effects of distant surfaces are confined to relatively low spatial frequencies in the shading field, meaning that we can expect signatures, called shading primitives, corresponding to shape ...

Diffuse interreflections cause effects that make current theories of shape from shading unsatisfactory. We show that distant radiating surfaces produce radiosity effects at low spatial frequencies. This means that, if a shading pattern has a small region of support, unseen surfaces in the environment can only produce effects that vary slowly over the support region. It is therefore relatively e...

In two experiments, we tested whether disparity and shading cues cooperated for surface interpolation. Observers adjusted a probe dot to/lie on a surface specified either by a sparse disparity field, a continuous stereo shading or monocular shading gradient, or both cues. Observers' adjustments were very consistent with disparity information but their adjustments were much more variable with sh...

Received: 15 August 2005 Revised: 21 December 2005 Accepted: 6 January 2006 Online publication date: 10 April 2006 Abstract Very early in the object recognition process the human visual system extracts shading information. While shading can enhance the visibility of structures, it can have a negative impact on the judgment of sizes of elements in a structure. In certain visualization systems th...

We propose decoupled sampling, an approach that decouples shading from visibility sampling in order to enable motion blur and depth-of-field at reduced cost. More generally, it enables extensions of modern real-time graphics pipelines that provide controllable shading rates to trade off quality for performance. It can be thought of as a generalization of GPU-style mul-tisample antialiasing (MSA...
