Radiosity and realistic image synthesis by Michael F Cohen( Book )

1 edition published in 1993 in English and held by 3 WorldCat member libraries worldwide

The goal of image synthesis is to create, using the computer, a visual experience that is identical to what a viewer would experience when viewing a real environment. Radiosity and Realistic Image Synthesis offers the first comprehensive look at the radiosity method for image synthesis and the tools required to approach this elusive goal. Basic concepts and mathematical fundamentals underlying image synthesis and radiosity algorithms are covered thoroughly. (A basic knowledge of undergraduate calculus is assumed). The algorithms that have been developed to implement the radiosity method ra

Complex luminaires illumination and appearance rendering by Edgar Velazquez Armendariz( Book )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Simulating a complex luminaire is expensive and slow, even using state-ofthe-art algorithms. A more practical alternative is to use precomputation to accelerate rendering. Prior approaches cached information on an aperture surface that separates the luminaire from the scene, but many luminaires have large or ill-defined apertures leading to excessive data storage and inaccurate results. In this dissertation, we separate luminaire rendering into illumination and appearance components. A precomputation stage simulates the complex light flow inside the luminaire to generate two data structures: a set of anisotropic point lights (APLs) and a radiance volume. The APLs are located near apparent sources and represent the light leaving the luminaire, allowing its near- and farfield illumination to be accurately and efficiently computed at render time. The luminaire's appearance consists of high- and low-frequency components which are both visually important. High-frequency components are computed dynamically at render time, while the more computationally expensive, low-frequency components are approximated using the precomputed radiance volume. Results are shown for several complex luminaires, demonstrating orders of magnitude faster rendering compared to the best global illumination algorithms and higher fidelity with greatly reduced storage requirements compared to previous precomputed approaches

Improving sampling and reconstruction techniques for radiosity by D Lischinski( Book )

1 edition published in 1991 in English and held by 1 WorldCat member library worldwide

Abstract: "The view-independent global illumination problem is rephrased as one of determining a radiance function across each surface in the environment. A new methodology for diffuse environments, based on the sampling and reconstruction of these functions is introduced. Within this context, the following problems are investigated: (i) where the radiance functions should be sampled; (ii) how to evaluate a radiance function at each sample; and (iii) how to reconstruct a radiance function from the set of samples. The new methodology relaxes some of the assumptions built into current radiosity algorithms. Results are presented which show that the new methodology yields significantly higher accuracy than existing radiosity methods."
Physically-Based Cloudy Sky Illumination by Daniel Thomas Knowlton( Book )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

We present a hybrid method combining both weather data and ground-based photography to generate physically-based full hemisphere cloudy sky illumination. We validate our illumination model using precise spatial and spectral radiance and total irradiance measurements of cloudy skies gathered over the timespan of several months using custom-built hardware. Our system reconstructs cloud volumes from fish-eye photographs utilizing satellite data to bound the vertical and horizontal extent of the cloud geometry. We estimate optical parameters for the cloud volumes from measured cloud micro-physical properties gathered from weather data. When combined with a physically-based light transport algorithm, our cloud illumination model accurately reproduces the highly varying anisotropic structure of a cloudy sky. In contrast to purely image-based techniques which produce static RGB illumination maps, by generating an actual cloud volume our method efficiently handles changes in sun direction, viewing angle, and cloud geometry. Our approach can accurately simulate a wide range of cloud and weather conditions and has applications for physically-based rendering, daylighting studies, and scene illumination
