6.8 Interpolation

Method on mglData (C++, Python): float Spline (float x, float y=0, float z=0) const

C function: float mgl_data_spline (const HMDT dat, float x, float y, float z)

Interpolates data by cubic spline to the given point x in [0...nx-1], y in [0...ny-1], z in [0...nz-1].

Method on mglData (C++, Python): float Spline1 (float x, float y=0, float z=0) const

C function: float mgl_data_spline1 (const HMDT dat, float x, float y, float z)

Interpolates data by cubic spline to the given point x, y, z which assumed to be normalized in range [0, 1].

Method on mglData (C++, Python): float Linear (float x, float y=0, float z=0) const

C function: float mgl_data_linear (const HMDT dat, float x, float y, float z)

Interpolates data by linear function to the given point x in [0...nx-1], y in [0...ny-1], z in [0...nz-1].

C function: float mgl_data_linear1 (const HMDT dat, float x, float y, float z)

Interpolates data by linear function to the given point x, y, z which assumed to be normalized in range [0, 1].

Method on mglData (C++, Python): float v (int i, int j=0, int k=0) const

C function: float mgl_data_get_value (const HMDT dat, int i, int j, int k)

Gets the value in specified cell of the data with border checking.

Method on mglData (C++, Python): float Spline5 (float x, float y, float z, float &dx, float &dy, float &dz) const

Interpolate by 5-th order splain the data to given point x, y, z which normalized in range [0, 1] and evaluate its derivatives.

C function: float * mgl_data_value (HMDT dat, int i, int j, int k)

Gets the pointer to data element.

C function: const float * mgl_data_data (const HMDT dat)

Gets the pointer to internal data array.
