📒Gpu Based Techniques For Global Illumination Effects ✍ László Szirmay-Kalos
✏GPU based Techniques for Global Illumination Effects Book Summary : This book presents techniques to render photo-realistic images by programming the Graphics Processing Unit (GPU). We discuss effects such as mirror reflections, refractions, caustics, diffuse or glossy indirect illumination, radiosity, single or multiple scattering in participating media, tone reproduction, glow, and depth of field. The book targets game developers, graphics programmers, and also students with some basic understanding of computer graphics algorithms, rendering APIs like Direct3D or OpenGL, and shader programming. In order to make the book self-contained, the most important concepts of local illumination and global illumination rendering, graphics hardware, and Direct3D/HLSL programming are reviewed in the first chapters. After these introductory chapters we warm up with simple methods including shadow and environment mapping, then we move on toward advanced concepts aiming at global illumination rendering. Since it would have been impossible to give a rigorous review of all approaches proposed in this field, we go into the details of just a few methods solving each particular global illumination effect. However, a short discussion of the state of the art and links to the bibliography are also provided to refer the interested reader to techniques that are not detailed in this book. The implementation of the selected methods is also presented in HLSL, and we discuss their observed performance, merits, and disadvantages. In the last chapter, we also review how these techniques can be integrated in an advanced game engine and present case studies of their exploitation in games. Having gone through this book, the reader will have an overview of the state of the art, will be able to apply and improve these techniques, and most importantly, will be capable of developing brand new GPU algorithms.

✏Illumination Conditions and Task Visibility in Daylit Spaces Book Summary : Illumination conditions are evaluated in typical building spaces based on detailed computer simulations, in order to characterize and quantify the effects of daylighting on task visibility. Examined are the effects of fenestration location and type on task contrast under daylit, electric-lit and combined conditions. The implications of the illumination conditions with daylighting on lighting and daylighting system design are discussed.
📒Suhrawardi And The School Of Illumination ✍ Mehdi Amin Razavi
✏Suhrawardi and the School of Illumination Book Summary : Shihab al-Din Yahya Suhrawardi, also known as Shaikh al-ishraq or the Master of Illumination, lived in the sixth century AH / twelfth century CE. His thoughts form a consistent and coherent philosophical system, and a close study of his writings in Persian reveals a theory of knowledge generally called 'Knowledge by Presence'. The elaborate web of myth and symbolism in Suhrawardi's philosophy articulates his theory of knowledge, an important subject in the ishraqi school of thought. Suhrawardi, who claims first to have discovered the truth and then embarked on a path to find the rational basis of his experiential wisdom, represents a thinker who tried to reconcile rational discourse and inner purification.

📒Illumination ✍ Christopher Alan Anderson
✏Illumination Book Summary : A metaphysical account as well as the author's own experience of illumination. This writing is a step into the light of a procreative metaphysics as well as being the author's most autobiographical statement. "The Man and Woman Spiritual Center is only expressed in an actual touch between a man and a woman. It cannot be expressed in any other way. That touch may range from a momentary conscious recognition to a full embrace, but a touch, one to another, it is. The Spiritual Center is not expressed through belief, pledge, worship, ritual, or the paying of alms. It is not something that can be institutionalized, dogmatized, or ratified. There isn't any prescribed path to take, master to follow, or status to attain for its expression. There is only a man and a woman, touching and expressing creation together." Illumination Author Bio: Christopher Alan Anderson (1950 - ) received the basis of his education from the University of Science and Philosophy, Swannanoa, Waynesboro, Virginia. He resides in the transcendental/romantic tradition, that vein of spiritual creativity of the philosopher and poet. His quest has been to define and express an eternal romantic reality from which a man and a woman could together stand in their difference and create a living universe of procreative love. Mr. Anderson began these writings in 1971. The first writings were published in 1985. On a personal note, when Mr. Anderson was asked to describe the writings and what he felt their message was he responded, "Spiritual procreation. Mankind has yet to distinguish the two sexes on the spiritual level. In this failure lies the root of our problems and why we cannot yet touch the eternal together. The message of man and woman balance brings each of us together in love with our eternal other half right now." keywords: Illumination, Procreation, Metaphysics, Spirit, Sexual, Touch, Male And Female, Consciousness...
📒Applied Illumination Engineering ✍ Jack L. Lindsey
✏Applied Illumination Engineering Book Summary : This comprehensive reference provides a practical, fully illustrated guide to design, specification, and application of state-of-the-art lighting, from the fundamentals of illumination to hands-on application. The full scope of light sources is examined and basic design methods for both indoor and outdoor lighting are presented, along with optimum application strategies for merchandise, offices, industrial settings, floodlighting, parking lots and street lighting. The second edition features a new chapter on skylights for industrial buildings, covering layout parameters and daylight availability calculations used to predict skylight performance. The chapter on lighting retrofits has been revised to emphasize methods for analyzing potential retrofits, examining how retrofit results can be predicted, how to evaluate retrofit proposals, and how to avoid common mistakes.
📒Practical Global Illumination With Irradiance Caching ✍ Jaroslav Krivanek
✏Practical Global Illumination with Irradiance Caching Book Summary : Irradiance caching is a ray tracing-based technique for computing global illumination on diffuse surfaces. Specifically, it addresses the computation of indirect illumination bouncing off one diffuse object onto another. The sole purpose of irradiance caching is to make this computation reasonably fast. The main idea is to perform the indirect illumination sampling only at a selected set of locations in the scene, store the results in a cache, and reuse the cached value at other points through fast interpolation. This book is for anyone interested in making a production-ready implementation of irradiance caching that reliably renders artifact-free images. Since its invention 20 years ago, the irradiance caching algorithm has been successfully used to accelerate global illumination computation in the Radiance lighting simulation system. Its widespread use had to wait until computers became fast enough to consider global illumination in film production rendering. Since then, its use is ubiquitous. Virtually all commercial and open-source rendering software base the global illumination computation upon irradiance caching. Although elegant and powerful, the algorithm in its basic form often fails to produce artifact-free mages. Unfortunately, practical information on implementing the algorithm is scarce. The main objective of this book is to show the irradiance caching algorithm along with all the details and tricks upon which the success of its practical implementation is dependent. In addition, we discuss some extensions of the basic algorithm, such as a GPU implementation for interactive global illumination computation and temporal caching that exploits temporal coherence to suppress flickering in animations. Our goal is to show the material without being overly theoretical. However, the reader should have some basic understanding of rendering concepts, ray tracing in particular. Familiarity with global illumination is useful but not necessary to read this book.
