create_surface_interpolation_lsq

create a least-squares surface interpolation from scattered data

create_surface_interpolation_lsq surface.obj xyz+values.txt output.txt [smoothness]

DESCRIPTION

create_surface_interpolation_lsq performs a least-squares interpolation of scattered data onto a surface mesh. The input data file contains xyz coordinates and associated values. The surface object provides the mesh onto which the data is interpolated. An optional smoothness parameter controls the regularization of the interpolation. The interpolated values are written to the output text file.

OPTIONS

This tool uses positional arguments only. There are no named options.

surface.obj
The input surface object file providing the interpolation mesh.
xyz+values.txt
A text file containing scattered data points with xyz coordinates and values.
output.txt
The output text file containing interpolated values at each surface vertex.
smoothness
An optional smoothness parameter controlling the regularization of the least-squares fit. Higher values produce smoother results.
