How to use the visualization of 3D distance error？

[XXXXLHBXXXX]

Dear author, could you tell me how the 3D distance visualization is done in your paper?

Hi, thank you for your interest in our work.
For your question, we visualized the 3D distance error via Python VTK. We just uploaded a script to this repository to give an example for this visualization. You can have more technical details by looking into the file 3d_dist_visual.py. Hope that will help. Please let us know if you have any questions. Thanks!
