Average surface distacne

[RRouhi]

Thanks for your nice library. Is the average surface distance calculated symmetrically? If not, could you guide me on how to obtain it
Thanks!

@RRouhi It looks like this function returns two separate ASD values in both directions (gt to pred, and pred to gt), so not symmetric.

Should be fairly easy to byo, get the distances and surface points distances_gt_to_pred, distances_pred_to_gt, surfel_areas_gt, surfel_areas_pred from compute_surface_distances()

then np.sum(distances_gt_to_pred * surfel_areas_gt) + np.sum(distances_pred_to_gt * surfel_areas_pred) / np.sum(surfel_areas_gt) + np.sum(surfel_areas_pred)
