A hybrid real-time visible surface solution for rays with a common origin and arbitrary directionsJohnson, Gregory Scott, 1971- 28 September 2012 (has links)
A fundamental operation in computer graphics is to determine for a given point and direction in a scene, which geometric surface is nearest this point from this direction and thus visible. Conceptually, the point and direction define a "ray". Z-buffer hardware can compute surface visibility for a set of rays with a common origin (i.e. eye point) and a regular pattern of directions in real-time. However, this hardware is much less efficient at performing other visibility computations such as those required to accurately render shadows. A more flexible solution to the visible surface problem is needed. This work introduces the irregular Z-buffer algorithm, which efficiently solves the visible surface problem for rays with a common origin and arbitrary directions. In addition, we identify several changes to classical graphics architectures needed for hardware acceleration of this algorithm. Though these modifications are incremental in nature (i.e. no new functional units are introduced), we show that they enable significant new capability. In tandem with the irregular Z-buffer algorithm, a GPU with these changes has applications in: shadow rendering, indirect illumination, frameless rendering, adaptive anti-aliasing, adaptive textures, and jittered sampling. We explore the performance of hard and soft shadow rendering in particular, by way of a detailed hardware simulator. / text

Worshipping the dark : the manifestations of Carl Gustav Jung's archetype of the shadow in contemporary WiccaDion, Nicholas Marc. January 2006 (has links)
Swiss psychoanalyst Carl Gustav Jung describes the encounter with the archetype of the shadow as the initial step to be taken by any individual seeking to initiate the individuation process. Jung observes a close relationship between this process and religion, suggesting that a psychologically beneficial religion can help guide the subject through individuation. Yet Jung finds few existing religious traditions that satisfy his criteria. Wicca, a neopagan religion popular in Europe and North America, presents itself at times as consciously psychological, striving to lead the practitioner to a goal of self-transformation, yielding a product that strangely resembles the individuated person. The objective therefore becomes not to criticize Wiccan religious claims, nor to deconstruct Jungian philosophy, but to identify the points of intersection between Wiccan theology/theology and Jungian psychology of religion, with a particular emphasis on the archetype of the shadow.

Previous issue date: 2014 / Resumo: Esta tese é resultado de uma pesquisa iniciada no mestrado e consiste na produção de estampas predominantemente provenientes de matrizes de gravura em metal e xilogravura, gravadas para serem capazes de permutar suas formas entre elas separadamente e formar combinações complementares, híbridas e aleatórias resultantes do processo de impressão. O principal objetivo é obter o maior número possível de estampas diferentes de um conjunto de matrizes e com isso, não só conciliar visualmente erotismo e anatomia humana na gravura, mas também ressaltar a variedade, como atributo dos organismos que se reproduzem sexualmente e perecem, para dar início a um novo ciclo / Abstract: This thesis is the result of a research started in the master's program and consists of the production of prints mainly from etching plates and woodcut, carved to be able to permute its shapes among them separately and create complimentary, hybrid and random combinations resulting from the printing process. The main goal is to obtain the largest possible amount of different prints from a set of plates and, with that, not only visually conciliate eroticism and human anatomy on the engraving, but also highlight the variety, as an attribute of the organisms that reproduce sexually and perish, in order to initiate a new cycle / Doutorado / Artes Visuais / Doutor em Artes

Experimentations in Construction, Light, Shadow, and ArchitectonicsHorner, David L. 05 1900 (has links)
The problem concerning this investigation is determining some of the possibilities of combining painting, architectonic constructions, and shadows produced by the controlled lighting of the structure. Chapter I is a brief history of experimentations in these areas during the twentieth century. This history assists in defining what has been done in the past, and reveals some directions for the future. Chapter II concerns three areas of study 1) the selection of the constructed forms mounted on canvas panels, 2) the lighting experimentations and their results, 3) the use of painted shadows to create an ambiguous pattern. This research concludes that a synthesis of these various art elements is not only possible, but aesthetically pleasing.

Automatic Removal of Complex Shadows From Indoor VideosMohapatra, Deepankar 08 1900 (has links)
Shadows in indoor scenarios are usually characterized with multiple light sources that produce complex shadow patterns of a single object. Without removing shadow, the foreground object tends to be erroneously segmented. The inconsistent hue and intensity of shadows make automatic removal a challenging task. In this thesis, a dynamic thresholding and transfer learning-based method for removing shadows is proposed. The method suppresses light shadows with a dynamically computed threshold and removes dark shadows using an online learning strategy that is built upon a base classifier trained with manually annotated examples and refined with the automatically identified examples in the new videos. Experimental results demonstrate that despite variation of lighting conditions in videos our proposed method is able to adapt to the videos and remove shadows effectively. The sensitivity of shadow detection changes slightly with different confidence levels used in example selection for classifier retraining and high confidence level usually yields better performance with less retraining iterations.

Naar analogie van schaduwen aan de wand : een wijsgerige interpretatie van 'de schaduw als kunstwerk' aan de hand van Plato's grotvergelijkingHoedekie, Nelson G. U. (Nelson Gustaaf Urbain) 03 1900 (has links)
Thesis (MPhil)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: In this thesis, 'shadow' is investigated as an object of thought and (analogically
connected to this) of perception. This dialectical process is structured through
means of a series of experiments and Plato's allegory of the cave, which is
interpreted as a process directed towards selfconciousness. This process is further
explained through thinkers such as, Blumenberg, Heidegger, Levinas en Voegelin.
The purpose of this study is to break with the self-evident way in which 'shadow' is
'normally' treated and to bring back about a sense of astonishment for it. / AFRIKAANSE OPSOMMING: In hierdie tesis word die 'skaduwee' as waarnemingsobjek en (analogies verwant
daaraan) as denkobjek ondersoek. Hierdie dialektiese proses word gestruktureerd
met behulp van 'n aantal eksperimente en Plato se grotgelykenis, wat geinterpreteer
word as programmaties van die proses van selfbewuswording. Hierdie proses word
verder toegelig aan die hand van denkers soos Blumenberg, Heidegger, Levinas en
Voegelin. Die doel van die ondersoek is om die vanselfsprekendheid waarmee daar
met die fenomeen van die skaduwee omgegaan word te deurbreek en weer
verwondering daarvoor op te roep. / NEDERLANDSTALIGE SAMENVATTING: In deze thesis wordt de 'schaduw' als waarnemingsobject en (analogisch verwant
daaraan) als denkobject onderzocht. Dit dialectische proces wordt gestructureerd
met behulp van een aantal experimenten en Plato's grotvergelijking, die
geïnterpreteerd worden als een proces gericht op zeltbewustwording. Dit proces
wordt verder toegelicht aan de hand van denkers zoals, Blumenberg, Heidegger,
Levinas en Voegelin. Het doel van het onderzoek is om de vanzelfsprekendheid
waarmee met het fenomeen van de 'schaduw' omgegaan wordt, te doorbreken en er
opnieuw verwondering voor op te roepen.
