SGI IRIS 4D
The SGI IRIS series of terminals and workstations from Silicon Graphics was produced in the 1980s and 1990s. IRIS is an acronym for Integrated Raster Imaging System. Overview 68000 The early systems up to IRIS 3000 use the Motorola 68000 series of processors originally, and later models feature early-generation MIPS processors. These systems run the GL2 operating system, a predecessor of the IRIX operating system, which is based on UniSoft UniPlus System V Unix. GL2 uses a proprietary windowing system named mex (Multiple EXposure). The first model, the IRIS 1000, was shipped around November 1983 with an 8 MHz Motorola 68000 CPU. It is a graphics terminal intended to be attached to a VAX-11 system running either VAX/VMS or BSD Unix. The related IRIS 1200 terminal has a 20-slot backplane in its cabinet versus the 10-slot backplane of the IRIS 1000. The IRIS 1400 Workstation (also known as the IRIS Workstation) was shipped only in 1984. It has a 10 MHz Motorola 68010. MIPS Th ...

Silicon Graphics
Silicon Graphics, Inc. (stylized as SiliconGraphics before 1999, later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS) was an American high-performance computing manufacturer, producing computer hardware and software. Founded in Mountain View, California in November 1981 by Jim Clark, its initial market was 3D graphics computer workstations, but its products, strategies and market positions developed significantly over time. Early systems were based on the Geometry Engine that Clark and Marc Hannah had developed at Stanford University, and were derived from Clark's broader background in computer graphics. The Geometry Engine was the first very-large-scale integration (VLSI) implementation of a geometry pipeline, specialized hardware that accelerated the "inner-loop" geometric computations needed to display three-dimensional images. For much of its history, the company focused on 3D imaging and was a major supplier of both hardware and software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OpenGL
OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering. Silicon Graphics, Inc. (SGI) began developing OpenGL in 1991 and released it on June 30, 1992; applications use it extensively in the fields of computer-aided design (CAD), virtual reality, scientific visualization, information visualization, flight simulation, and video games. Since 2006, OpenGL has been managed by the non-profit technology consortium Khronos Group. Design The OpenGL specification describes an abstract API for drawing 2D and 3D graphics. Although it is possible for the API to be implemented entirely in software, it is designed to be implemented mostly or entirely in hardware. The API is defined as a set of functions which may be called by the client program, alongside a set of named intege ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IRIS GL
IRIS GL (Integrated Raster Imaging System Graphics Library) is a proprietary graphics API created by Silicon Graphics (SGI) in the early 1980s for producing 2D and 3D computer graphics on their IRIX-based IRIS graphical workstations. Later SGI removed their proprietary code, reworked various system calls, and released IRIS GL as the industry standard OpenGL.

Silicon Graphics Image
Silicon Graphics Image (SGI) or the RGB file format is the native raster graphics file format for Silicon Graphics workstations. The format was invented by Paul Haeberli. It can be run-length encoded (RLE). FFmpeg and ImageMagick, among others, support this format. Background Common file extensions are: ;.sgi or .rgb: 3 colour channels ; .rgba: 3 colour channels and alpha ;.bw or .int: black and white ;.inta: black and white and alpha This format was originally developed for IRIX. The master files of the '' SVT High Definition Multi Format Test Set'' are SGIs. Frame 200 of the ''ParkJoy'' sequence in this set (15722.sgi, 3840×2160, 47.4 MB) was used in WebP comparisons. Technical Details SGI image format use big endian order. Image data scan from left to right from bottom to top. Header File Signature/Magic Number Should equal 0x01 0xda for SGI file. Compression If no compression equal 0; 1 for RLE compression. Bytes Per Pixel Channel Value is 1 for 8 bit pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIPS Architecture
MIPS (Microprocessor without Interlocked Pipelined Stages) is a family of reduced instruction set computer (RISC) instruction set architectures (ISA)Price, Charles (September 1995). ''MIPS IV Instruction Set'' (Revision 3.2), MIPS Technologies, Inc. developed by MIPS Computer Systems, now MIPS Technologies, based in the United States. There are multiple versions of MIPS: including MIPS I, II, III, IV, and V; as well as five releases of MIPS32/64 (for 32- and 64-bit implementations, respectively). The early MIPS architectures were 32-bit; 64-bit versions were developed later. As of April 2017, the current version of MIPS is MIPS32/64 Release 6. MIPS32/64 primarily differs from MIPS I–V by defining the privileged kernel mode System Control Coprocessor in addition to the user mode architecture. The MIPS architecture has several optional extensions. MIPS-3D which is a simple set of floating-point SIMD instructions dedicated to common 3D tasks, MDMX (MaDMaX) which is a more exten ...

SGI Crimson
The IRIS Crimson (code-named ''Diehard2'') is a Silicon Graphics (SGI) computer released in 1992. It is the world's first 64-bit workstation. Crimson is a member of Silicon Graphics's SGI IRIS 4D series of deskside systems; it is also known as the 4D/510 workstation. It is similar to other SGI IRIS 4D deskside workstations, and can use a wide range of graphics options (up to RealityEngine). It is also available as a file server with no graphics. This machine makes a brief appearance in the movie ''Jurassic Park'' (1993) where Lex uses the machine to navigate the IRIX filesystem in 3D using the application fsn to restore power to the compound. The next year, Silicon Graphics released a rebadged, limited edition Crimson R4400/VGXT called the Jurassic Classic, with a special logo and SGI co-founder James H. Clark's signature on the drive door. Features * One MIPS 100 MHz R4000 or 150 MHz R4400 processor * Choice of seven high performance 3D graphics subsystems * Up to 256 MB memo ...

SGI Indigo
The Indigo, introduced as the IRIS Indigo, is a line of workstation computers developed and manufactured by Silicon Graphics, Inc. (SGI). SGI first announced the system in July 1991. The Indigo is considered one of the most capable graphics workstations of its era, and was essentially peerless in the realm of hardware-accelerated three-dimensional graphics rendering. For use as a graphics workstation, the Indigo was equipped with a two-dimensional framebuffer or, for use as a 3D graphics workstation, with the Elan graphics subsystem including one to four Geometry Engines (GEs). SGI sold a server version with no video adapter. The Indigo's design is based on a simple cube motif in indigo hue. Graphics and other peripheral expansions are accomplished via the GIO32 expansion bus. The Indigo was superseded generally by the SGI Indigo2, and in the low-cost market segment by the SGI Indy. Technical specifications The first Indigo model (code-named ''Hollywood'') was introduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorola 68000 Series
The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel's x86 microprocessors. They were best known as the processors used in the early Apple Macintosh, the Sharp X68000, the Commodore Amiga, the Sinclair QL, the Atari ST, the Sega Genesis (Mega Drive), the Capcom System I (Arcade), the AT&T UNIX PC, the Tandy Model 16/16B/6000, the Sun Microsystems Sun-1, Sun-2 and Sun-3, the NeXT Computer, NeXTcube, NeXTstation, and NeXTcube Turbo, the Texas Instruments TI-89/TI-92 calculators, the Palm Pilot (all models running Palm OS 4.x or earlier) and the Space Shuttle. Although no modern desktop computers are based on processors in the 680x0 series, derivative processors are still widely used in embedded systems.
