Decorator class which adds the functionality of estimating normals at the data points.
void setTriangleInterpolator(TriangleInterpolator *inter) override
Sets an interpolator.
QVector< PointState > * mPointState
Vector who stores, it a point is not on a breakline, if it is a normal point of the breakline or if i...
bool alreadyestimated
Is true, if the normals already have been estimated.
Vector3D * getNormal(int n) const
Returns a pointer to the normal vector for the point with the number n.
TriangleInterpolator * mInterpolator
Association with an interpolator object.
QVector< Vector3D * > * mNormVec
Vector that stores the normals for the points. If 'estimateFirstDerivatives()' was called and there i...

Enumeration for the state of a point. Normal means, that the point is not on a BreakLine,...
An interface for objects which accept features via addFeature(s) methods.
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Point geometry type, with support for z-dimension and m-values.
Interface for Triangulation classes.
virtual QgsMesh triangulationToMesh(QgsFeedback *feedback=nullptr) const =0
Returns a QgsMesh corresponding to the triangulation.
virtual bool saveTriangulation(QgsFeatureSink *sink, QgsFeedback *feedback=nullptr) const =0
Saves the triangulation features to a feature sink.

bool swapEdge(double x, double y) override
Reads the content of a taff-file.
void setTriangleInterpolator(TriangleInterpolator *interpolator) override
Sets an interpolator object.
void eliminateHorizontalTriangles() override
Eliminates the horizontal triangles by swapping.
int addPoint(const QgsPoint &p) override
Adds a point to the triangulation.
bool calcPoint(double x, double y, QgsPoint &result) override
Calculates x-, y and z-value of the point on the surface and assigns it to 'result'.
bool calcNormal(double x, double y, QgsPoint &result) override
Calculates the normal at a point on the surface and assigns it to 'result'.
This is an interface for interpolator classes for triangulations.
Class Vector3D represents a 3D-Vector, capable to store x-,y- and z-coordinates in double values.
