đ megabyte of VRAM (also capable of holding/executing code and data).ĜD-ROM Drive with the following features:.Math Co-Processor custom designed by NTG for accelerating fixed-point matrix operations.Super Fast BUS Speed (50 Megabytes per second).Separate BUS for video refresh updates (VRAM is dual ported).O Special filtering capable of creating effects such as 3D sound. O On chip instruction SRAM and register memory. Ođ7 separate 16-bit DMA channels to and from system memory. O Specifically designed for mixing, manipulating, and synthesizing CD quality sound. Ĝustom 16-bit Digital Signal Processor (DSP) with the following features:.
O Supports transparency, translucency, and color-shading effects. O Texturemap source bitmaps can be 1,2,4,6,8, or 16 bits per pixel and are RLE compressed for a maximum combination of both high resolution and small storage space. OĚble to map a rectangular bitmap onto any arbitrary 4-point polygon. OĜapable of producing 9-16 million REAL pixels per second (36-64 Mpix/sec interpolated), distorted, scaled, rotated and texture mapped.
The heart of the system is two Graphics and animation : This in theory allows multiple components to be operating simultaneously, with less bus contention problems than would be found in a standard single-bus design. Instead of a straightforward single bus configuration, it seems to have a multiple bus configuration. What are the detailed specs of the system?Ī: According to information from an article about the 3DO in Popular Science, the 3DO has an interesting design. This is really 16 million internal 16-bit pixels that are then interpolated as they are displayed on the screen to 640 by 480 pixel resolution, quadrupling the number of pixels displayed on screen. What does it mean when 3DO product literature says that the system can "animate 64 million pixels per second?"Ī: The system is capable of animating up to 64 million 16-bit on-screen pixels per second. The interpolation can be turned on and off via software.Ī: The 3DO can do 16 bit graphics with CLUTs(Color Look Up Tables) drawn from 24 bits, or it can do true 24 bit graphics. The internal resolution is interpolated into an anti-aliased 640x480 pixel display. There are no other resolutions available. The 16-bit mode is almost always used for animations, while the 24-bit mode is used mostly for still pictures. However, the 3DO has an internal resolution of 320x240 or 320x480, with each pixel being either 24-bits or 16-bits.
What is the resolution of the 3DO system?Ī: The resolution displayed on screen is 640x480.
