geodesic.circles: Compute geodesic circles and ball stats for given vertices.

Description

Compute geodesic circles and ball stats for given vertices.

Usage

geodesic.circles(surface, vertices = NULL, scale = 5)

Arguments

surface

an rgl::tmesh3d or freesurferformats::fs.surface instance. Can be a character string, which will be loaded as a surface file if it exists.

vertices

positive integer vector, the vertex indices for which to compute the stats. If NULL, it is computed for all vertices.

scale

double, surface area to be covered by patch in percent

Examples

if (FALSE) {
  sjd = fsaverage.path(TRUE);
  surface = subject.surface(sjd, 'fsaverage3', hemi='lh');
  gc = geodesic.circles(surface);
  vis.data.on.subject(sjd, 'fsaverage3', morph_data_lh = gc$radius);
  vis.data.on.subject(sjd, 'fsaverage3', morph_data_lh = gc$perimeter);
}
