Detailed Description

The projLib package first provides projection of curves on a plane along a given Direction. The result will be a 3D curve. The ProjLib package provides projection of curves on surfaces to compute the curve in the parametric space.

It is assumed that the curve is on the surface.

It provides :

• Package methods to handle the easiest cases :
• Line, Circle, Ellipse, Parabola, Hyperbola on plane.
• Line, Circle on cylinder.
• Line, Circle on cone.
• Classes to handle the general cases :
• Plane.
• Cylinder.
• Cone.
• Sphere.
• Torus.
• A generic class to handle a Curve from Adaptor3d on a Surface from Adaptor3d.
