PRINCIPLES OF MODERN THREE-DIMENSIONAL MODELLING

Architecton: Proceedings of Higher Education №3 (39) September, 2012

Modern electronic three-dimensional modelling has been classified by the availability of the history of construction of an object (parametric, nonparametric, combined) and by elements of construction of a model (framed, polygonal, superficial, solid-state, finite-element, generative).

Four principles of modern three-dimensional modelling in industrial design have been developed: traditional, inverse, generative, and interactive.

The generative and interactive modelling principles have fewer stages, allow the modelling time to be reduced and most complex forms to be modelled in contrast to traditional and inverse principles. With the generative modelling principle, it is possible to operate separately the geometry and information about the geometry, the latter making it possible to edit the parameters of the form of the object at any time during the modelling.

Polycompound surfaces have been classified and differentiated by visual quality, and three classes of surface have been identified: "A", "B" and "C". However, class A modelling is currently accessible to the two first principles only.

Guidelines have been developed, recommending that bachelor degree students study the traditional and inverse modelling principles: year 1 – framed modelling; year 2 – fundamentals of surface and solid-state modelling; year 3 – finite-element modelling; year 4 – synthesis of the types of modelling. At master’s degree level, when the requirement is to develop scientific thinking, the recommendation is to study two modern principles of modelling: generative and interactive.
