ABSTRACT:
A curved surface image processing apparatus100according to the present invention that can render an object at higher speed and in higher quality by performing image processing using NURBS data includes: a data input unit101for receiving NURBS data; a coordinate transformation unit102for performing coordinate transformation on NURBS data; an animation control unit103for controlling animation data of each frame to be rendered; a data transformation unit104for transforming NURBS data into rational Bezier data; a patch division unit105for subdividing a rational Bezier surface patch; a normal determination unit106for calculating normals of control points of a divided surface patch; a perspective transformation unit107for performing perspective transformation on a divided surface patch; and a rendering unit108for rendering a surface patch.
