A method, system, and computer-readable storage medium are disclosed for tessellating a trimmed parametric surface comprising a parametric surface and a trim curve. The parametric surface may be tessellated to produce a set of polygons approximating the parametric surface. A first polygon of the set of polygons in which a first point on the trim curve is located may be determined. A second point on the trim curve may be projected into a plane, wherein the plane is determined by the first polygon. A set of one or more additional polygons of the set of polygons may be projected into the plane. A second polygon of the set of one or more additional polygons in which the second point on the trim curve is located may be determined. |
