Member Data Documentation

bool proland::Vertex::isControl

If this point is a control or regular vertex.

float proland::Vertex::l

Real curvilinear coordinate along the curve.

This coordinate is not automatically computed. It must be computed explicitely with Curve::computeCurvilinearLength(). The initial value is -1.

float proland::Vertex::s

Pseudo curvilinear coordinate along the curve.

This coordinate is computed in a recursive way during curve subdivisions (see Curve::flatten()). For top level curves it must be computed explicitely with Curve::computeCurvilinearCoordinates(). The initial value is -1.
