ABSTRACT:
A curved surface designing method comprises the steps of a first step of inputting edge shape data of n-sides of a curved surface, a second step of obtaining a regular n-sided polygon in a parameter space on the basis of the given data of n sides, a third step of calculating distance parameters on the basis of the regular n-sided polygon obtained by the second step, a fourth step of calculating blending values on the basis of the distance parameters, a fifth step of mapping an inner point D of the regular n-sided polygon onto the respective sides so as to calculate boundary parameters, a sixth step of calculating at least one of three-dimensional coordinate points, and, if necessary, tangent vectors, on sides which are boundaries of the curved surface on the basis of the boundary parameters, and a seventh step of calculating arbitrary points on the curved surface on the basis of the distance parameters, the blending values, the three-dimensional coordinate points of the respective sides, and, if necessary, the tangent vectors, of the respective sides.
