OCC.LProp module¶

Handles local properties of curves and surfaces.Given a curve and a parameter value the following computationsare available :- point,- derivatives,- tangent,- normal,- curvature,- centre of curvature,- Locals curvature’s extremas,- Points of inflection,Given a surface and 2 parameters the following computationsare available :- for each parameter:- derivatives,- tangent line,- centre of curvature,- point,- normal line,- maximum and minimum curvatures,- principal directions of curvature,- mean curvature,- Gaussian curvature.-Level : Public.All methods of all classes will be public.
