blur_surface

blur a surface object using a Gaussian kernel

blur_surface input.obj output.obj fwhm dist_ratio [values]

DESCRIPTION

blur_surface smooths a surface object by applying a Gaussian blur kernel with the specified full width at half maximum (fwhm). The dist_ratio parameter controls the ratio of the search distance to the FWHM, determining how far neighbouring vertices contribute to the smoothing.

If values are provided, the per-vertex values are blurred rather than the vertex positions themselves.

The blurred surface (or values) is written to the output file.
