SUMMARY:Real-time Computer Graphics: An overview of popular approaches and
  techniques - Ben Naccarato\, Churchill College

DESCRIPTION:Computer graphics has come a long way over the years\, making 
 more and more lifelike displays. Raytracing techniques have been used to c
 reate images to a very high level of realism\, and can handle optical effe
 cts like shading\, shadows\, reflection and refraction\, but with a severe
  computation cost. Why does it take hours for a single frame to render in 
 a CG film\, when modern videogames can smoothly handle 60 frames per secon
 d? This talk will have a look at how real-time graphics is handled differe
 ntly\, the techniques used to achieve similar effects and the shortcuts th
 at can be made to achieve this in a fraction of a second. We will cover th
 e various stages involved in representing a 3D world and displaying it on 
 a 2D screen\, and look at real time algorithms such as Shadow mapping and 
 Environment mapping.
