The modelling technical forms by bicubic surfaces

Abstract

The problems of forming of bicubic surfaces are being analysed. These surfaces can ensure smooth passage from one segment of surface to other segment, so , it is possible to reduce the nimber of segments. The smooth passage is urgent for design auto, aeroplane, etc. The calculation of coefficient of bicubic Bezier surface is analysed too. In our mind, it is necessary to examine this surface, because the operating with the points for forming the form of surface is very practical.
