Abstract:
A system, devices and methods to reduce the volume of data required to represent three-dimensional smooth cylindrical curves and to ray-trace these three-dimensional smooth cylindrical curves using a set of geometric primitives which have implicit curvature.

Claim (Index 4):
The method of  claim 1 , wherein the Dupin cyclide arcs are generated by:\n calculating a normal vector extending from each of the two consecutive line segments and using the intersection point of the vectors as a center point of the Dupin cyclide, a radius of the cyclide arc being the distance between the center point and a start point of one of the vectors; setting a local coordinate system of the Dupin cyclide such that an XY plane is the plane defined by the two normal vectors, the origin being at the intersection of the two normal vectors; choosing an orientation of the X axis; setting a starting and ending angle of the Dupin cyclide arc so that the total arc angle is equal to the angle between the normal vectors; calculating radii at the start point and the end point of the Dupin cyclide arc by interpolation at points where the normal vectors extend from respective line segments using radii at each end of the respective line segments; and displacing the Dupin cyclide arc in the local XY plane until its end points lie on the polyline.
