Rock Mapper stores georeferenced face photographs and 3D LiDAR Scans as textured meshes. A textured mesh consists of 3 files:
- OBJ file which includes the 3D mesh
- JPG file which includes the texture (JPG)
- MTL file which is the Material file and links the JPG to the OBJ
All 3 files must share the same file name and need to be located in the same folder so they can be opened by 3rd party software packages.
