Item Computer generated lighting techniques: the study of mood in an interior visualisation(2009-09-21T10:11:12Z) Marshall, Bronwyn GillianAbstract The report investigates computer generated (CG) lighting techniques with a focus on the rendering of interior architectural visualisations. With rapid advancements in CG technology, the demand and expectation for greater photorealism in visualisations are increasing. The tools to achieve this are widely available and fairly easy to apply; however, renderings on a local scale are still displaying functionality and lack visual appeal. The research discusses how design principles and aesthetics can be used effectively to create visual interest and display mood in the visualisation, with strong attention to the elements that are defined as the fundamentals in achieving photorealism. The focus is on a solid understanding of CG lighting techniques and principles in order to achieve high quality, dynamic visualisations. Case studies examine the work of lighting artist James Turrell and 3D artist Jose Pedro Costa and apply the findings to a creative project, encompassing the discussions in the report. The result is the completion of three photorealistic renderings of an interior visualisation, using different CG lighting techniques to convey mood. The research provides a platform for specialisation in the 3D environment and encourages a multidisciplinary approach to learning.Item Salience strategy: connectivity, aesthetics and the learning mind(2009-05-29T10:23:41Z) Burnett, Richard Leslie GeorgeThis dissertation adds to the many arguments already made for the value of art (cultural artifact) in teaching and learning. The special approach developed here concludes with the articulation of Salience Strategy. The argument firstly questions the value of seeing intelligence as a problem-solving faculty. It continues by examining consciousness, memory and the imagination as both the ground and substance of intellection. It argues that, amongst other things, interconnectedness, reiterative pathways and networks are central to the operation of consciousness and therefore, are central to its epiphenomenal attributes like intelligence. As education should strive for greater intellectual functioning so it should, therefore, strive to harness the paradigms of interconnectedness, reiterative pathways and networks. The art object, (device, gesture, statement), it is proposed, is valuable when deployed as hubs in networks of ideas allowing learners to form patterns of unexpected and creative linkages enhancing both memory, curiosity and a capacity for imaginative and associative thinking. Learning becomes movement through a landscape of complex objects and outgrowths. Two salience itineraries are explored in this dissertation. The first in relation to concepts overheard during learner conversations over the duration of a school week, and a second, exploiting my own work as an artist, selected work by the British artist Richard Long, and some of the issues raised in the theoretical discussion of consciousness and networks.Item Ken Saro-Wiwa's art and the aesthetics of non-silence(2008-03-03T07:35:25Z) George, Austin Tamuno-OpuboAbstract: This work examines the writings and other discursive practices of Ken Saro- Wiwa, the Nigerian dissident writer and minority rights activist, who was hanged by the military authorities in Nigeria in November 1995. Until his death, Saro- Wiwa had been a tireless campaigner against transnational oil corporations for devastating the local ecology while prospecting for oil, and against the Nigerian state for repressing oil-bearing minority communities through its nationalist bureaucratic practices. After his death, the ideas of this writer contained in over twenty literary texts and detention diaries continue to frame and inflame agitational discourses in the Niger Delta region of Nigeria and beyond. The aim of this work is to identify, interpret and critique the vast miscellany of oppositional modalities employed by Ken Saro-Wiwa and his Ogoni community in their tussles with nationalist modernity in Nigeria. Using interpretive protocols derived mainly from minority discourse theory, I attempt to examine and assess the place and significance of Ken Saro-Wiwa within the corpus of dissident culturalist discourse in Africa and beyond.
