Help on applying the Tf_param output to a mesh

[vinodgovindan]

I am testing how well probreg works for a task i am trying to do. I am trying to align two mesh models (one is the base model and the other is the target that needs to be aligned) and then save the aligned mesh model.
The prob reg wroks accurately with the point cloud model. i get 100% alignment. But when i try and save the point cloud i lose quality.

To get around this i use your probreg to gt the tf_param and then use the T, rot and scale values on the mesh.
While i am able to successfully apply the translation and scale values,, the rotation appears to have no effect.

Is there any recommended approach you have to achieving a good success? I use pymeshlab and/or Open3d for applying these values to the mesh.

In open 3D i am unable to get the Translation and Rotation (from the tf_prarm) to be applied and in pymesh i am unable to the rotation to be applied. I use the registration_cpd funtion to the tf_param.

will really appreciate any inputs you may have on this.
