Draw small 3D spheres at given brain mesh vertices. Supports full brain (2 meshes) as well.

Draw small 3D spheres at given brain mesh vertices. Supports full brain (2 meshes) as well.

Usage

highlight.vertices.spheres(surface, vertices, ...)

Arguments

surface

an fs.surface instance, see subject.surface function. Can also be a hemilist of surfaces, in which case the vertices can be indices over both meshes (in range 1..(nv(lh)+nv(rh))).

vertices

vector of positive integers, the vertex indices. Values which are outside of the valid indices for the surface will be silently ignored, making it easier to work with the two hemispheres.

...

Parameters passed to highlight.points.spheres.

Note

This function will draw into the current window and add to the scene, so it can be called after visualizing a mesh. See the example.

Examples

if (FALSE) { # \dontrun{
lh_surf = subject.surface('~/data/study1', 'subject1',
 surface = "white", hemi = "lh");
vis.fs.surface(lh_surf, style="semitransparent");
highlight.vertices.spheres(lh_surf,
  vertices = c(3225L, 4300L, 5500L),
  color = c("green", "blue", "red"));
} # }
