Member Data Documentation

CurvePtr proland::BasicCurvePart::curve [protected]

The original curve.

int proland::BasicCurvePart::end [protected]

End of the interval, inside path, to which this curve part corresponds (inclusive).

int proland::BasicCurvePart::orientation [protected]

The orientation of this curve part.

0 means that the curve's start and end are given by start and end respectively. 1 means that the curve's start and end are given by end and start respectively (note that end is always greater than start).
