Help with region.txt, regions_symmetry.txt and symmetry_groups.txt

[hobbitsyfeet]

Hi, I'm a bit confused on the specifics of these files. I've read your instructions and thought I knew how it worked. Later I found out I interpreted it and am lost on how to properly structure it.

I tried my own data, but thought I should get it working on the data used for the paper to get it working.
Using assembly_airplanes ~

body pnts 1
wings pnts 1
tail_wings pnts 1
fuselages pnts 1
body pnts 1

Here, I do not understand why it will not work with anything else except this format.

body
wings wings
tail_wings tail_wings
fuselage
body

I thought wings would be symmetrical with itself. Though, in the paper it said each part should be uniquely labelled....?

symmetry_group reflection 0
single_label_indices 0
pair_label_indices 1 2 3 4

Anyways, I believe this is causing issues when generating sampling points, which I would also like to get working.

I reach MeshViewerCore::compute_ground_truth_cuboids and when I reach this, it fails saying there is no sample file points.

ret = load_object_info(mesh_, cuboid_structure_, mesh_filepath.c_str(), LoadDenseSamplePoints);
	if (!ret) return;

Maybe I'm just not sure how the sampled points are created, but some help would be greatly appreciated.

----------UPDATE----------

This ended up an error with loading sampled points. I was wondering about the method you used to create these? I believe you load it in the format of (Barymetric points x y z, vertices x y z, normal).

Was there a third party method of generating these? If not, is there some code you can provide?

Thanks~
