Hello,

I have two meshes. Low resolution and a high resolution one. High resolution
mesh is just a part of the Low res. mesh. Computation of the Hausdorff
distance doesn't work (0 samples), could you explain me the problem please?
Could I perform distance computation somehow between the mesh and it's aligned
part?

thank you.

I also tried to apply Hausdorff distance to two identical meshes, one mesh was
shifted (one can see it visually). This time there were sampled points, but
the result was strange:
Filter: Hausdorff Distance computed
Filter: Sample 43140
Filter: min : 0.000000 max 0.000000
Filter: mean : 0.000000 RMS : 0.000000
Filter: Values w.r.t. BBox Diag (157.584946)
Filter: min : 0.000000 max 0.000000
Filter: mean : 0.000000 RMS : 0.000000

I use MeshLab v1.2.3 revision: 4312, vcg revision: 3752.

I found a mistake for these errors. Before you apply Hausdorff distance
filter, you need to freeze all the matrix (of course if you did any
transformations before)!

Thanks for the tip!
