\brief the minimal example for aligning two meshes
|
||||
|
||||
This file contain a minimal example for aligning two meshs.
|
||||
|
||||
Example call:
|
||||
./trimesh_align_pair mesh1.ply mesh2.ply output.ply
|
||||
|
||||
output.ply will contain mesh2.ply rotated in order to be aligned to mesh1.ply
