1. Computer Graphics and Game Technology

2. Thanks to …
An Epic Games
For help in producing these slides

3. Graphics Hardware = Real-Time Rendering
3D Scene = Mesh of Vertices and Lines
2D Screen Image = Pixels
? What is “Real Time” ?
? How do we create the mesh ?
3D Studio Max, Maya, Blender, UnrealEd

4. Graphics Hardware = Real-Time Rendering
3D Scene = Mesh of Vertices and Lines
2D Screen Image = Pixels

5. PC - Graphics Let’s say screen is 1024 x 768 pixels
Each pixel is 3 bytes (R G B)
Refresh rate is 60 times per sec (Hz)
Then we need 140 MegaBytes each sec
PCI 132 MBytes/sec AGP 2000 MBytes/sec PCIe = Mbytes/sec

This is a SOLID MASS, we must carve-out or sculpt our rooms in this mass.

20. Why? Computer Game Technology: fastest growing industry in UK
engages with our youth, our future
Immersive Environments (IEs)
Development of educational and training materials
Urban Search and Rescue (USAR) = big US research initiative
Medical Applications
Vehicle for deployment of maths and physics education

21. Research at UoW within Computing
Use of UnrealTournament Game Engine :
Production of IEs for visualisation, s, and indeed any data
Virtual worlds for Architecture, …
Development of training applications for commerce, the public sector (police, rescue services, armed forces, medicine).
