Each project created with Zephyr is saved as .zep format.


Each workspace also includes the photographs used for the 3D reconstruction, therefore it is possible to open, send and edit the path of .zep files irrespective of the location of the image files. Nevertheless it will not be possible to start one of the four phases of 3D reconstruction or make changes involving photograph usage.


Click on File > Open or Open Recent to open a .zep project, or click on Save or Save As to save your work.


If you have a command-line reconstruction made with 3DF Samantha, the Structure from Motion algorithm, you can import that by selecting File > Load from 3DF Samantha.



  • Load .psz files


This function is not available in 3DF Zephyr Lite and 3DF Zephyr Free.


Within Zephyr you can be load psz project by clicking on File > Load from .psz file.


Cameras, sparse point cloud and mesh of psz project are imported In Zephyr and you can now start  some 3D reconstruction phases such as the dense point cloud or texture generation.



  • Load pictures with known camera parameters


This function is not available in 3DF Zephyr Lite and 3DF Zephyr Free.


In Zephyr you can manually import all the parameters of a camera before starting the  cameras orientation phase; cameras will be calibrated without being adjusted by the Structure from Motion algorithm.


To load the parameters just click on File> Load images with known camera parameters.


It is also possible to use .XMP files to import a specific camera configuration and skip the sparse 3D reconstruction: this is the preferred workflow for fixed rigs.
