ITEM #1
WTE 7400 PC SOLIDS MODELING ENGINEER
INTRODUCTION
The WTE 7400 Solids Modeling Engine (SME) is a special hardware system
for the IBM PC - AT which generates vector graphics, solid graphics, and
floating-point results at extremely high speed. The WTE 7400 is a 172
board set, and will typically use the IBM Professional Graphics
Controller as the graphic output device.
The SME acts a as a graphics accelerator to provide fast three
dimensional wireframe transformations (zoom and rotation, for example),
and the painting of realistic shaded images with hidden surface removal.
This means that design engineers will have an affordable desktop tool
with enough graphics and floating-point power to quickly perform complex
tasks on a personal computer.
The WTE 7400 contains a microcoded processor with a RAM based
microstore. The microcode for the applications is loaded into the
microstore as part of the boards initialization. Modified or totally
customer microcode can be loaded in place of the routines supplied by
WEITEK, giving the OEM the ability to reprogram the board for specific
floating point tasks, allowing a wide range of products using the same
hardware.
The WTE 7400 come with drives software for use with IBM's Professional
Graphics Controller, which provides a 640 by 480 pixel display with up
to 256 colors selected from a 4096 color palette.
FEATURES
Interactive 3-D hardware transformations ( rotation, translations,
scaling, and clipping as well as either and yon (30-D) clipping.
Perspective and pick support.
Hardware vector graphics support including chained vectors, rational
quadratic polynomials, and cubic Bezier curves.
Hardware solid graphics support including hidden surface removal,
variable shading over surfaces (Gouraud shading), and translucent
surfaces.
Modeling functions for solids graphics includes light source modeling,
representation of curved surfaces with bicubic Bezier patches, and the
ability to process any convex polygon.
32 bit array processor delivering 8 million floating-point operations
per second (Megaflops)
Clipping the Z direction allows "cut away" views of object (section
planes)
Typical 3D vector processing speed (transformation and clipping) of
4,000 vector/second when driving an enhanced IBM Professional Graphics
Controller.
Typical solid graphics processing speed (transformation, clipping,
Shading, and display or 60,000 shaded pixels/second on an enhanced IBM
Professional Graphics Controllers.
8k by 96 bit of microstore
Provided to OEMs with powerful microassembler to allow customer floating
point applications.
Boards do not interfere with normal operations of any IBM standard
hardware of software.
