How to visualize the 3D textured mesh with georeference

The 3D Textured Mesh that PIX4Dmapper and PIX4Dmatic generate 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 used, the 3D Textured Mesh will have the same precision as the mesh in the rayCloud of PIX4Dmapper and the 3D view in PIX4Dmatic.

Offset file in 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?.

When importing the .xyz file in other software, such software will generally require 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 generated in the params folder. This file contains the projection of the output coordinate system.

Offset file in PIX4Dmatic

The offset of the project is available after exporting the mesh as an output.

The project_name_offset.xyz file is stored in the params folder under project_name\exports\project_name_offset.xyz
