n the thesis we will consider a topic in computer aided geometric design, which studies curves in a form understandable by computer. We will describe some basic building blocks such as Bernstein basis function, Bezier curve, de Casteljau's algorithm and blossom. Moreover we will be describing a new variant of the blossom, the h-blossom. The h-blossom is introduced by altering diagonal property of the standard blossom which enables us to have more control over the shape of the curve. We will continue the thesis by studying properties of h-blossom. In the end, we will present an algorithm for computing the h-blossom
