[MINC-users] How to create a "wireframe" surface object?

[Najmeh Khalili M.]

Thanks Lasse, Jason.

I couldn't get the tags_to_spheres produce pretty markers, but
reducing the surface opacity allowed me to ray_trace subcortical
objects.

The plygons_to_lines works well. (Is there a way to subsample
the polygons? I tried "smooth_lines" on the polygon.obj,
but it doesn't seem to change anything. I tried it with
distance 0.2 and 100!!)

Cheers
Naj
