Next-Generation Consoles Brenden Schubert & Nathaniel Williams With a Special talk by John F. Rhoads on Video Game Ethics Sega Dreamcast Sega Dreamcast • Billed by Microsoft as: The Windows CE Game Machine for the New Millennium • Released September 9, 1999 • Hitachi SH4 RISC CPU – 200MHz at 360 MIPS/1.4FLOPS • Memory: 16MB main, 8MB video, 2MB sound Dreamcast Graphics • NEC PowerVR Second Generation – 3 million polygons/second peak rendering rate – Perspective-Correct Texture Mapping – Point, Bilinear, Trilinear and Anisotropic Mipmap filtering – Gouraud shading – Z-buffering – Colored light sourcing Dreamcast Graphics • NEC PowerVR Second Generation – – – – – Full scene anti-aliasing Hardware-based Fog Bump mapping 16.77 million colors Hardware-based texture compression – Super sampling – Shadow and Light volumes Movie Time ! (ctaxi5.mov) Sony Playstation 2 Playstation 2 Stats •300 MHz 128 bit RISC “Emotion Engine” chip (from Toshiba) •32 MB Rambus memory •Standard DVD-ROM (CD-ROM compatible) Playstation 2 Graphics • • • • 150 MHz clock 4 MB video memory 75 Million Polygons Per Second is absolute max 20 Million per second with 48 pixel quads, Z-buffering, alpha blending, and MIP mapping Playstation 2 Graphics • MIP-mapping • Bi-linear filtering • Surface/Edge Antialiasing • Texture-correction • 32 bit Z-buffering Playstation 2 Special Features • Plays DVDs right out of the box • USB, PCMCIA, and “I-Link” I/O ports for modem and other peripherals • Backwards compatibility with Playstation 1 games • Hard Drive available in 2001 Movie time… Video Game Ethics Why are Ethics Important? • Standard of Human Worth • Need a common Standard to Gauge Excellence • Commonly ignored • Video Game Ethics Vs Video Game Links What are Video Game Ethics? • A set of general rules used to determine whether or not a game has been “won.” Examples • Game Genie • Playing for other people • Using FAQ’s • Warping • Konami Code • Turbo Controllers Perfect Example • Bushido Blade Want to know more? • www.people.virginia.edu/~jmr6u/gamethic.html Nintendo Gamecube Game Cube Stats • Powered by IBM PowerPC "Gekko“ (405mhz) • 24MB system memory • Proprietary DVD format (sorry guys – difficult to copy) • Modem and Ethernet Capabilities Game Cube Graphics • Graphics chip “Flipper” 202.5mhz – – – – 2MB framebuffer 1MB texture cache 24 bit color 24 bit z-buffer • Image Processing Functions: – – – – – Fog Subpixel anti-aliasing HW light x8 Alpha blending Virtual texture design Game Cube Graphics • More Image Processing Functions – Multi-texture mapping – Bump/environment mapping – MIP-mapping, bilinear filtering, real-time texture decompression (S3TC), etc. – Real-time decompression of display list – HW motion compensation capability (If you care about sources: http://cube.ign.com/news/23962.html) Game Cube Graphics Actual display capability: 6 million to 12 million polygons per second (display capability assuming actual game with complexity model, texture, etc.) Movie Time ! Don’t be so surprised Link, it’s not a big deal.
