Description

Interperate 3D data and returns smoothed xz, yz curves.

Syntax

bool get_interpolated_xz_yz_curves_from_3D_data( Curve& x_curve , Curve& y_curve, const vector& x_data, const vector& y_data, const vector& z_data, int bAutoReduceSize = false)

Parameters

x_curve: [output] interpolated x_z_curve at the Y where y_z_curve is maximum
y_curve: [output] interpolated y_z_curve at the X where x_z_curve is maximum
x_data: [input] vector for the x of 3D data
y_data: [input] vector for the y of 3D data
z_data: [input] vector for the z of 3D data
bAutoReduceSize: [input] Auto reduce size for regular data set to improve speed

Return

Returns TRUE on success and FALSE on failure.
