The efficiency of pilots’ training on aviation
simulators is in many respects determined by the quality included in a simulator
structure of a display system for a mapping of a visual situation. To imitate
known visual situation varying in real-time mode, the display system should,
first of all, respond two requirements: to have good representational
capabilities and high processing speed. Tendency to execute the first
requirement results in increasing the number of primitives and pixels of a
screen, processed during frame, i.e. at the end is connected to the second
requirement. To increase processing speed of a display system it should be
built on the basis of specialized computing facilities. The advance in this
area, basically, is connected with the implantation in graphics hardware new
structural solutions and technologies.
To increase realness of visual situation displaying to a great extend,
having kept thus a real-time mode, it is possible by usage of primitives with
more broad representational capabilities in combination to rational
organization of image synthesis computing process. As a geometrical primitive
it is offered to use a part of a displayed surface (integrated primitive).
For each graphic operation of image synthesis process it is necessary to
select or to create optimum on performance algorithm, and then "to
dock" algorithms in united computing process. Thus the processing speed of
algorithm is offered to be increased by rational construction of graphic
transformations process.
The graphic transformations analysis displays,
that some operations are most effectively executed in one coordinate system,
and the others - in another, and the calculators working in miscellaneous
coordinate systems, should interchange the data. The result is multisequencing
and piping of computing process, that allows rationally to select structure of
display system computing facilities.
