PROGRESSIVE
TRENDS OF MODERN ENGINEERING COMPUTER GRAPHICS DEVELOPMENT
Computer information technologies play important role in many spheres of human life at current stage of society development.
One of the main components of modern information technologies is computer graphics tools. It is difficult to imagine interactive communication between a man and a computer without them.
The existence of
color graphics displays, printers, scanners, etc., as well as appropriate
interfaces of not only various applied programs, but also operating systems as
a part of computer equipment confirms the mentioned above fact.
In addition to
using in the culture, daily life, advertising, entertainment and other areas of
human activities geometric methods are widely used in science, education and
manufacturing sectors, particularly in industry [1].
Appropriate area
is called by engineering computer graphics. It combines various directions of
geometric modeling, ie, the creation of drawings, schemes, charts, diagrams,
virtual solids, etc. by using points, lines, surfaces and volume elements,
which are mathematical abstractions.
Applied geometry,
uniting analytical, descriptive, differential, combinatorial, projective,
multidimensional, computational and the other types of geometry is the
methodological scientific basis for the indicated discipline.
Nowadays
engineering computer graphics is practically realized at the following
mathematical modeling packages as Matlab [2], Mathcad [3], Maple [4] and at
such computer aided design systems (CAD/CAM/CAE) as Nastran [5], SolidWorks
[6], AutoCAD [7], CATIA [8], etc.
Animation and visualization of multidimensional objects [9] is the progressive tendency of the development of mathematical packages in the aspect of geometric modeling.
It is typically for CAD/CAM/CAE systems to use widely three-dimensional geometric parametric models, their associative connection with the appropriate design and technological documentation, as well as the integrated consideration at design stage creation, manufacture and operation of products.
The methodology
of structural parametric modeling and optimization of different technical
objects and processes is a rather promising trend of modern science [10-12].
The mentioned
methodology is based on the possibility of geometric models to change their
configuration in the best way in order to achieve the optimal required
technical characteristics of created products, their manufacture and operation.
In this way the
tendency of combining capabilities of mathematical modeling packages,
CAD/CAM/CAE systems, PDM (Product Data Management) and PLM (Product Life-cycle
Management) information technologies is an obviously quite perspective
direction.
Modern
engineering computer graphics is widely used in mechanical engineering,
metallurgy, electronic, chemical and other industries, construction, education,
medicine and other fields of human activity.
In addition to
this it is necessary to highlight that the scope of the modern engineering
computer graphics effective use has been steadily growing by constantly
improving the capabilities of computer hardware, its software, perfecting the
methodology and mathematical tools based on the achievements of applied
geometry.
