The 3D Textured Mesh that Pix4Dmapper generates is not georeferenced. It has coordinates in a local coordinate system centered around the project.
Some external viewers permit you to add the offset of this file and place the 3D Textured Mesh at its correct position. If this is used, the 3D Textured Mesh will have the same precision as the mesh in the rayCloud of Pix4Dmapper.
The offset of the project is generated after step 1. Initial Processing. The project_name_offset.xyz file is stored in the params folder under: project_name\1_initial\params\project_name_offset.xyz
For more information about the params folder: What does the Output Params Folder contain?.
Note: The project_name_offset.xyz file contains the offset coordinates, but it does not store references about the coordinate system and datum, which are defined by the selected output coordinate system in Pix4Dmapper.
When importing the .xyz file in other software, such software will generally require, in a graphic interface, which datum and coordinate system is being used. In that case it is possible to use the project_name_wkt.prj file that is generated in the params folder. This file contains the projection of the output coordinate system. For more information: What does the Output Params Folder contain?.
At the moment, only the .osgb and .slpk file formats are georeferenced.

I can't get the mesh and point cloud to align. I've uploaded the .xyz file. It all seems lined up on the desktop but won't align in the cloud.
Hi Eric,
Is this not aligned enough?
(Same view/position)
Let me know if it is satisfactory for you.

Hello,
I kindly want to know which external viewers might permit the addition of the offset file to the 3D textured mesh for a correct georeferencing? Thanks!
Raphael AtimbireYou could try meshlab. Most 3rd party Softwares should be able to import the offset file for georeferencing.
