Actually I have decimated (ie., reduced the meshes)in the given object using planar option. Now, I need to check the hausdroff distance between original mesh and decimated mesh.

Is this a suitable approximation?

enter image description here

It'a a Geometry Nodes modifier which returns the maximum distance between 2 meshes, when their object- origins are coincident. Depending on how you want to use this number, it could be stored on the mesh, or used elsewhere.

  • $\begingroup$ @DeepakDeep See Edit: That's why I've asked how you want to use this result.. I don't know, it may need to be scripted? What are you going to do with this number? $\endgroup$

  • $\begingroup$ Actually based on that, if the max. distance is within limit then I will further proceed with decimation. $\endgroup$ Commented Mar 16, 2023 at 10:27
  • $\begingroup$ @DeepakDeep, it does sound as if someone should write a script or operator to converge on the right level of decimation to meet your threshold, using a combination of limited dissolve and find nearest. That could automate the search. If this is on the right track, you should edit your question to make that clearer. $\endgroup$
