Study and realization of three dimensional character modeling system based on spline curve;

After analyzing profoundly the function and its DXF group codes of various kind of spline curves in AutoCAD software as well as programming verification based on object ARX development environment, this paper finally reversed their developing technique and mathematic models of biarc spline, B-spline and NURBS(non-uniform rational B-spline) curve in AutoCAD software.

Based on the divisibility of Bézier curves,the paper provides a generating algorithm of spline curves and further promotes the algorithm to the spline curves of the kind by means of the transformation matrix of spline curves.
