    A description is given of PEX, an extension to the X Window System that is designed to efficiently support PHIGS and much of the functionality in the proposed PHIGS+extension to PHIGS PEX (PHIGS, PHIGS+, and Extensions to X) allows each window on the display to act as a complete, independent, virtual 3D graphics workstation. The overall architecture of PEX is examined, with emphasis on how it fits... View full abstract»

    A software system for developing interactive scientific visualization applications quickly, with a minimum of programming effort, is described. This application visualization system (AVS) is an application framework targeted at scientists and engineers. The goal of the system is to make applications that combine interactive graphics and high computational requirements easier to develop for both pr... View full abstract»

    The benefits of the virtual pixel maps technique in the support of high-quality rendering operations are described. A dedicated frame buffer with a fixed number of bits per pixel is inappropriate for implementing high-quality rendering techniques within the framework of a graphics computer system. The virtual pixel maps feature is an elegant abstraction for solving problems that inherently require... View full abstract»

    A description is given of the Titan Graphics Supercomputer. The primary design philosophy was to have as little redundant hardware as possible and to make as much of the hardware available to compiled application code as possible. This led to a design with multiple parallel processors, each with an integer unit and a vector floating-point unit. The system provides 3D graphics and image processing,... View full abstract»

    RISC (reduced-instruction-set-computer) CPU design concepts are used as the basis for a more general design philosophy applicable to graphics. The 3D graphics subsystem for the Apollo DN10000 is based on applying a RISC philosophy to the rendering problem. All structure-walking and floating-point computations are handled in the general-purpose CPU(s), and a simple, fast-cycle-time drawing engine s... View full abstract»

    A class of machines known both as superworkstations and graphics supercomputers has become available. These workstations provide computing performance previously available only on supercomputers and graphics performance at levels never before available. The author presents a model that differentiates graphics architectures on the basis of graphics computation partitioning and places superworkstati... View full abstract»

    A description is given of the Intel i860 processor, which was designed for use in low-cost 3D graphics workstations. These products need high performance to support the operating system, simulations, transforms, and shading calculations. The integer unit provides high performance for Unix and other operating systems, the floating-point unit provides high throughput for computationally intensive ap... View full abstract»

    The accurate display of synthetic images requires careful attention to color. Simply modeling color with an RGB triplet leads to color aliasing. Most color antialiasing techniques begin with a specification of color as a spectral energy distribution. There are two apparent hurdles to be overcome to support the spectral model in rendering systems. One is the difficulty of interactively designing a ... View full abstract»
