Thesis (MA, BSc)
MA Computer Animation Thesis, University Of Teesside 2003
This project's report, titled Investigation Of Low Polygon Modeling & Character Animation Techniques In A Game Developing Context, is an attempt to discuss the production of a number of low polygon game models (as used in contemporary commercial real-time games and with a strict polygon count) with the real emphasis on animating a diverse and varying set of moves for them (again as they exist in today's entertainment software), all showcased on an accompanying animation video piece. There is a lengthy research discussion on the limitations real-time games place on these tasks today, a short mention on the what the future standards could be, as well as the human anatomy, artistic (concept art) and 3D software package restrictions applied (with all sources of material fully referenced where applicable). Moreover, there is a step-by-step illustrative development diary of all the modeling work carried out and a particularly technical section offering insight on the specific process used to rig and weight the low polygon character to be used for the animations. A large part of the report is dedicated on discussing how the animations were implemented by paying particular attention to key issues for each and every one of them as well as their purpose and various challenging parts. All the animations are also broken down in illustrations so that the most important steps leading towards their development are demonstrated. Pdf
BSc In Computer Studies (Visualisation) Thesis, University Of Derby 2002
This thesis tackles the subject of image compression techniques, and in particular near-lossless ones. An insight on the importance of image compression is offered and also definitions of lossy and lossless compression are given (with brief, fully-illustrated, examples of the most important lossless and lossy techniques/algorithms today and their relevance, strengths/powers and disadvantages/limitations in the context of modern image compression). Additionally, a thorough description of near-lossless image compression techniques is also offered. The development part of the thesis focuses on applying a near-lossless compression technique to a range of colour images, albeit the standard JPEG compression one. This is achieved via an application created in IDL, which is a fourth generation visualisation programming language. Lossy and lossless compression was also achieved in the same application to illustrate and contrast the differences between different types of image compression. The final chapter deals with presenting a relationship between "objectively lossless" and "subjectively lossless". This was achieved by employing an Electronic Questionnaire developed in Visual Basic used to measure the subjective fidelity of the images, which was presented, along with the test images, to twenty test subjects.
