Function documentation

std::shared_ptr<CardinalSplineModel> fast::CardinalSplineModel::create(std::vector<Vector2f> controlPoints, float globalProcessError, float localProcessError)

Create instance.

Parameters
controlPoints List of control points for the cardinal spline.
globalProcessError
localProcessError
Returns instance

void fast::CardinalSplineModel::setControlPoints(std::vector<Vector2f> controlPoints)

Give a set of control points. The control points are assumed to be connected so that vector k, is connected to vector k-1 and k+1, and the last is connected to to the first to form a closed loop.
