GENERATION OF KNOT NET FOR CALCULATION OF QUADRATIC TRIANGULAR B-SPLINE SURFACE OF HUMAN HEAD

Ján Mihalík

   This paper deals with calculation of the quadratic triangular B-spline surface of the human head for the purpose of its modeling in the standard videocodec MPEG-4 SNHC. In connection with this we propose an algorithm of generation of the knot net and present the results of its application for triangulation of the 3D polygonal model Candide. Then for the model and generated knot net as well as an established distribution of control points we show the results of the calculated quadratic triangular B-spline surface of the human head including its textured version for the texture of the selected avatar.

Keywords: triangular B-spline, quadratic surface, knot net, human head, 3D polygonal model
