Paul E. Haeberli is an American computer graphics programmer and researcher.
Paul Haeberli studied for a Bachelor of Science degree in electrical engineering at the University of Wisconsin–Madison, United States. [1]
Haeberli was recruited by James H. Clark to join Silicon Graphics during the company's founding. Haeberli's early work included code, developed with David J. Brown and Mark Grossman, for SGI's first product – the IRIS 1000. Between 1983 and 1999, Haeberli continued at Silicon Graphics in Silicon Valley, California. [2] He worked on the early MEX window system for Silicon Graphics workstations. [3] He was also involved in non-photorealistic rendering (NPR) techniques in computer graphics, producing software to implement this approach. [4] He devised the Silicon Graphics Image (SGI) format for graphics files. Later, he became an initial member of the research team at Silicon Graphics.
After Silicon Graphics, Haeberli joined Shutterfly, where he developed much of the online technology and image-processing foundations for the system that Shutterfly later employed in production.[ citation needed ]
Subsequently, he founded Lamina Design, which allows freeform structures to be constructed from sheet material using computer-based techniques. The company is based in Madison, Wisconsin. [5]
The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that define the WIMP "window, icon, menu and pointing device" paradigm.
IRIX is a discontinued operating system developed by Silicon Graphics (SGI) to run on the company's proprietary MIPS workstations and servers. It is based on UNIX System V with BSD extensions. In IRIX, SGI originated the XFS file system and the industry-standard OpenGL graphics system.
Silicon Graphics, Inc. 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.
Fahrenheit was an effort to create a unified high-level API for 3D computer graphics to unify Direct3D and OpenGL. It was designed primarily by Microsoft and SGI and also included work from an HP-MS joint effort.
IRIS GL 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.
The Indy, code-named "Guinness", is a low-end multimedia workstation introduced on July 12, 1993. Silicon Graphics Incorporated (SGI) developed, manufactured, and marketed Indy as the lowest end of its product line, for computer-aided design (CAD), desktop publishing, and multimedia markets. It competed with Intel x86 computers, and with Windows and Macintosh, including using their files and running their applications via software emulation. It is the first computer to come standard with a video camera, called IndyCam. Indy was repackaged as a server model called Challenge S. Indy was discontinued on June 30, 1997 and support ended on December 31, 2011.
Geometric manipulation of modelling primitives, such as that performed by a geometry pipeline, is the first stage in computer graphics systems which perform image generation based on geometric models. While geometry pipelines were originally implemented in software, they have become highly amenable to hardware implementation, particularly since the advent of very-large-scale integration (VLSI) in the early 1980s. A device called the Geometry Engine developed by Jim Clark and Marc Hannah at Stanford University in about 1981 was the watershed for what has since become an increasingly commoditized function in contemporary image-synthetic raster display systems.
MEX was a windowing system created by Silicon Graphics, used on 68k-based IRIS systems and early IRIS 4D systems. MEX was originally loaded over a network through the utilization of GL1 routines kept on a remote host machine, usually a VAX. When the IRIS 1400 workstation and GL2-W (IRIX) were introduced, MEX was allowed to run locally. MEX was used in IRIX from the GL2-W2.1.0 release to the 4D1-2.3 release.
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.
Non-photorealistic rendering (NPR) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism. NPR is inspired by other artistic modes such as painting, drawing, technical illustration, and animated cartoons. NPR has appeared in movies and video games in the form of cel-shaded animation as well as in scientific visualization, architectural illustration and experimental animation.
IRIX Interactive Desktop is a discontinued desktop environment normally used as the default desktop on Silicon Graphics workstations running IRIX. The IRIX Interactive Desktop uses the Motif widget toolkit on top of the X Window System found on most Unix systems. The default window manager on the IRIX Interactive Desktop is 4Dwm.
Kurt Akeley is an American computer graphics engineer.
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.
Xsgi is the X Window System (X11) server for the IRIX-based graphical workstations and servers from Silicon Graphics (SGI). Xsgi was released in 1991 with IRIX 4.0 on the SGI Indigo workstation.
Materials Studio is software for simulating and modeling materials. It is developed and distributed by BIOVIA, a firm specializing in research software for computational chemistry, bioinformatics, cheminformatics, molecular dynamics simulation, and quantum mechanics.
IrisVision is an expansion card developed by Silicon Graphics for IBM compatible PCs in 1991 and is one of the first 3D accelerator cards available for the high end PC market. IrisVision is an adaptation of the graphics pipeline from the Personal IRIS workstation to the Micro Channel architecture and consumer ISA buses of most modern PCs of the day. It has the first variant of IRIS GL ported to the PC, predating OpenGL.
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.
Computer graphics deals with generating images and art with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research.
Eclipse was a professional 2D image editing program available on Silicon Graphics and Windows workstations. Designed to manipulate high-resolution images like digitized movie frames and photographs for print, it offered color correction tools, image processing effects, rudimentary paint features, and spline-based drawing and masking.
The history of computer animation began as early as the 1940s and 1950s, when people began to experiment with computer graphics – most notably by John Whitney. It was only by the early 1960s when digital computers had become widely established, that new avenues for innovative computer graphics blossomed. Initially, uses were mainly for scientific, engineering and other research purposes, but artistic experimentation began to make its appearance by the mid-1960s – most notably by Dr Thomas Calvert. By the mid-1970s, many such efforts were beginning to enter into public media. Much computer graphics at this time involved 2-dimensional imagery, though increasingly as computer power improved, efforts to achieve 3-dimensional realism became the emphasis. By the late 1980s, photo-realistic 3D was beginning to appear in film movies, and by mid-1990s had developed to the point where 3D animation could be used for entire feature film production.
