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

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

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

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 = 4000+ Mbytes/sec

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

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