Developments in High Performance CGI Systems
نویسندگان
چکیده
The work to be described uses a model based on a polygon representation and uses a Geometry Processor sub-system, with a flexible architecture known as MAGIC. This system performs the transformation of the polygon from the 3-D representation to the 2-D perspective projection to the viewing screen co-ordinates and also provides a clipping operation optional in 3-D or 2-D. Two different types of scan conversion system are described, the first the Zone Management Processor uses the coherence inherent in the polygon and the second system based on a Line Processor uses coherence with spans.

The effect of interval and continuous training on the content of perilipin 1, ATGL and CGI-58 in visceral adipose tissue of obese male rats
Background and Aim: Obesity is an excessive accumulation of fat and its storage due to an imbalance between energy intake and energy consumption. High-fat diets, through inhibition of lipolysis enzymes can lead to increase in obesity and also many metabolic diseases. While exercise can activate these enzymes and lead to a change in the amount of visceral adipose tissue and reduce obesity. The p...
متن کاملChallenges and developments of bioretention facilities in treating urban stormwater runoff; A review
Bioretention or rain garden is a preferable low impact development (LID) approach due to its characteristics which reflect natural water cycle processes. However, this system is still little understood and quite complicated in terms of design and implementation due to many technical considerations. Hence, this paper gives a review of the challenges and developments for the use of bioretention f...

متن کاملThe Visorama System: A Functional Overview of a New Virtual Reality Environment
The recent developments in image-based rendering have enabled a representation of virtual environments based on a simulation of panoramas, which we call virtual panoramas. Current virtual panorama systems do not provide a natural and immersive interaction with the environment. We propose a new system that uses hardware and software components to provide a natural and immersive interaction with ...
