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 Adaptor3d_Curve on a Adaptor3d_Surface.
