Sažetak
Owing to computer design modern age is characterized by dull, sequential, zigzag or circular positioning shapes in the pattern repeat to a lesser extent. it can be easily accomplished by using computer graphics tools such as CorelDRAW and the like. If a design idea of positioning shapes is expanded by a wish that positioned shapes should create new design constructions, whereby these pattern elements should be as large as possible and harmonized with the lines of the environment, it cannot be achieved by these graphics tools. Such comlex patterns can be generated using additional software utilizing mathematical formulee or algorithms and additional subroutines by means of which curve point transformation of shapes, positioning to curves of pre-selected small shapes as well as continual curvilinear construction can be created. The basis of this additional software is based on the fact that a multicolored horizontal straight line in the composition area converts itself into a curve on a separate matrix by means of two mathematical functions, whereby one defines the y-axis and the other the x-axis, new points in a new composition, and on grounds of the given point also its color in the composition area. The specific feature of this program lies in the fact that all points which cross the frame of this composition return mathematically and graphically in its frames, over both axes by which the unbrokenness of the design composition or the continuity of the patterns is guaranteed over fabric width and length. Based on their dimensions the transformed shapes may exceed the measures in the composition area, depending on the algorithm and its variables. The transformation is pursued on the monitor and by using several commands various pattern designs can be created with the same formule. The main feature in curvilinear positioning small shapes on the surface of a new composition is the choice of curves and mutual distance of points to which shapes are fitted. In continuous curvilinear pattern designs the construction is the graphic and mathematical connection of two distant points in the design in relation to two adjacent points in the composition area. The programs are applicable in the textile and graphic arts industry.
