                                  VROOM
               Virtual Reality using Object Oriented Methods

VROOM is a 3D graphics library developed at the Department of Automatic 
Control & Systems Engineering, University of Sheffield, to allow the creation
of virtual environments on a standard PC (386 or 486). Although still under
development, VROOM already boasts the following features:

*   Using 32 bit fixed-point arithmetic, Mode X graphics and a unique polygon
    fill algorithm, VROOM can manage over 20 frames/sec with 100 flat shaded
    polygons on a 486SX 25MHz, and over 50 frames/sec on a 486DX 30MHz using 
    a local bus

*   Uses 256 colour graphics to provide 16 different colours with 16 shades,
    and the palette can be user-customised

*   Unlike some public-domain libraries, faces need not be convex polygons. 
    Any non-complex polygons can be handled

*   Viewing angle can be at any position (within numerical ranges), and any
    angle (to 0.1 degree)

*   Object-oriented techniques mean that visual objects can be created and
    manipulated easily and objects can be heirarchically linked together to
    allow the creation of complex dynamic objects

*   A full range of object transformations are available and objects can be
    programmed to transform at a continuous rate over a time period, and a
    series of transformations can be programmed to govern an object's
    trajectory

*   Will work on any 386 or 486 PC equipped with a standard VGA card, and can 
    be manipulated using keyboard or mouse

*   Drivers are being written to allow the interface of low-cost immersion
    hardware
