Documentation

A class for rendering one dimensional manifolds (curves in space). It can render a group a space curves, using either lines or cylinders. It also includes the ability to place a director field, or "ribbon", along the curve.

DVlines_line_status line_status

Defines how the lines will be drawn. Options are thin lines, tubes, or not at all.

DVlines_ribbon_status ribbon_status

Defines how the ribbons will be drawn. Options are as flat surfaces or not at all.

virtual DVobject* copy()

We also want a routine that returns a pointer to a copy of the object created with new.
