  • open graphics library — (graphics, library)   (OpenGL) A multi-platform software interface to graphics hardware, supporting rendering and imaging operations. The OpenGL interface was developed by Silicon Graphics, who license it to other vendors. The OpenGL graphics interface consists of several hundred functions operating on 2D and 3D objects, supporting basic techniques, such as modelling and smooth shading, and advanced techniques, such as texture mapping and motion blur. Many operations require a frame buffer. OpenGL is network-transparent, and a common extension to the X Window System allows an OpenGL client to communicate across a network with a different vendor's OpenGL server. OpenGL is based on Silicon Graphics' proprietary IRIS GL.
  • open trading protocol — Internet Open Trading Protocol
  • orthogonal projection — a two-dimensional graphic representation of an object in which the projecting lines are at right angles to the plane of the projection. Also called orthogonal projection. Compare isometric (def 5).

  • pacific daylight time — the version of Pacific Standard Time that is in use when daylight saving time is being observed
  • packed encoding rules — (protocol, standard)   (PER) ASN.1 encoding rules for producing a compact transfer syntax for data structures described in ASN.1, defined in 1994. PER provides a much more compact encoding then BER. It tries to represents the data units using the minimum number of bits. The compactness requires that the decoder knows the complete abstract syntax of the data structure to be decoded, however. Documents: ITU-T X.691, ISO 8825-2.
  • physically challenged — See example at challenged (def 1).
  • plate glass insurance — Plate glass insurance is insurance coverage against damage to or breakage of large panes of glass such as shop windows.

  • polygenic inheritance — the heredity of complex characters that are determined by a large number of genes, each one usually having a relatively small effect.
  • programmed cell death — a normal, genetically regulated process leading to the death of cells and triggered by the presence or absence of certain stimuli, as DNA damage.

  • replacement algorithm — The method used to determine which entry in an associative cache to flush to main memory when it is desired to cache a new block of data. The "least recently used" algorithm flushed the block which has not been accessed for the longest time. A random replacement algorithm picks any block with equal probability.

  • tool command language — (language)   /tik*l/ (Tcl) An interpreted string processing language for issuing commands to interactive programs, developed by John Ousterhout at UCB. Each application program can extend tcl with its own set of commands. Tcl is like a text-oriented Lisp, but lets you write algebraic expressions for simplicity and to avoid scaring people away. Though originally designed to be a "scripting language" rather than for serious programming, Tcl has been used successfully for programs with hundreds of thousands of lines. It has a peculiar but simple syntax. It may be used as an embedded interpreter in application programs. It has exceptions and packages (called libraries), name-spaces for procedures and variables, and provide/require. It supports dynamic loading of object code. It is eight-bit clean. It has only three variable types: strings, lists and associative arrays but no structures. Tcl and its associated GUI toolkit, Tk run on all flavors of Unix, Microsoft Windows, Macintosh and VMS. Tcl runs on the Amiga and many other platforms. See also expect (control interactive programs and pattern match on their output), Cygnus Tcl Tools, [incr Tcl] (adds classes and inheritence to Tcl), Scriptics (John Ousterhout's company that is the home of Tcl development and the TclPro tool suite), Tcl Consortium (a non-profit agency dedicated to promoting Tcl), tclhttpd (an embeddable Tcl-based web server), tclx (adds many commands to Tcl), tcl-debug.
