- Rick Tompane, 3DO VP Technology: "The core of the system is a pair of
- animation-cel engines working in parallel." Each engine is a complex
- graphics pipeline, capable of 3D transformation, shading and lighting,
- transparency control and texture mapping. The engines, whose exact
- architecture is still a closely guarded secret, are implemented in ASICs
- built by AT&T Microelectronics.
-
- Engines: theoretical peak of 64 million pixels/sec, 40-50 average.
- (16 bit CD-ROM = 1 Mpix/sec, 32 bit CD-ROM = 3 Mpix/sec. Whoa!)
-
- "A key to the system's consumer-level cost is that the images are kept in
- a simple but effective compressed format in main memory. The graphics
- processors manipulate the image in its compressed form. Expansion occurs
- only when a video processor extracts the frame from main memory and begins
- feeding it to the display. 'We use a little temporal, a little spatial,
- and a little color compression' Tompane said."
-
- + seperate custom DSP in one of the ASICs takes compressed audio and expands
- it into CD quality stereo
-
- + housekeeping, I/O and control tasks are handled by a 32-bit RISC, the
- ARM60.
-
- + 3DO Interactive Multiplayer accepts 3DO software, audio CDs, Kodak PhotoCD,
- and video CD-ROMs, eventually including MPEG.
-
- + >70 software houses signed so far, including Paramount, Virgin, Ocean,
- Dynamix (Sierra On-Line), Psygnosis, Maxis, and Spectrum HoloByte.
-
- + Companies license the system and build it, Matsushita (Panasonic) showed
- the first prototype at WCES.
-
- + Investors: Matsushita, AT&T, Time-Warner (!), MCA, Electronic Arts, and
- Kleiner Perkins Caufield & Byers (venture capital).

- "As the crowed watched, the 3DO system took a still image, pasted it onto
- the visible frame of a cube, then rotated the cube. It then made the cube
- transparent, so that the still image could be seen on all six faces as the
- cube rotated. It then bounced the cube around the screen, distorting it to
- make it appear to be a graphics-laden block of Jello. (old SGI trick?)
- The demonstrators also took a live feed from a camcorder, then manipulated
- the 15 fps video, squeezing, twisting, peeling, and stretching multiple
- representations of a 3DO employee's face. Next, the machine presented an
- image of a revolving globe made of 120 facets, and sent it bouncing around
- inside a 3D room; as this was going on, it orbited a graphic representation
- of a light bulb around the globe, rendering the appropriate shading in
- real time."
