Religion, possibly the most fanciful and certainly the most subjective domain of human behaviour, has particular challenges associated with its study. Attracting crowd healers, conjurers, the pious and the prophetic alongside comparativists and sceptics, it excites opinions and generalizations, whilst seldom explicitly staking out the territory for the discussions and means of knowledge in which it partakes. Increasingly, serious scholars argue that religious study needs to define and critique its own field, to distinguish itself from theology and other non-objective disciplines. Yet how do...

This book is about generating real time dynamic shadows in computer graphics. Our goal is to achieve fast shadow volume computation in a setting where lights and therefore also shadows may change on a per-frame basis. The book deals with optimizations and improvements upon the basic Shadow Volume Algorithm invented in 1977 by Crow. We look at some of the various recent optimization suggestions and use a practical approach to determine how many of these techniques can be successfully combined for an "ultimate" shadow volume algorithm.
