DualEdgeTriangulation * mTIN
Class Vector3D represents a 3D-Vector, capable to store x-,y- and z-coordinates in double values...
Definition: Vector3D.h:29
This is an interface for interpolator classes for triangulations.
Point geometry type, with support for z-dimension and m-values.
Definition: qgspoint.h:36
virtual void setTriangulation(DualEdgeTriangulation *tin)
Sets a Triangulation.
virtual bool calcPoint(double x, double y, QgsPoint *result SIP_OUT)=0
Performs a linear interpolation in a triangle and assigns the x-,y- and z-coordinates to point...
LinTriangleInterpolator()
Default constructor.
#define SIP_OUT
