Sažetak

Presented calculations and the choice of variables u,v iz [0,1] of the given basic surface j enable the creation of a versatile programme for the graphical processing of the characteristics not only of the helical but also of the rotational envelope surface F defined by the conical or cylindrical surface. Basic (conical or cylindrical) surface j can be generated from the basic curve defined by the vector function r(u), za u iz [0,1] (1) applying a class of transformations defined by the matrix T(v), for v iz [0,1] (2). The combined analytical and synthetical method resultes in the parametric equations of the characteristics (3) and in the coordinates of the meridian section points.
