File Format
Saving files and projects need to be noticed.
What kind of data you need to save depends on which steps you completed and what files you want to save.

Mapping Project |
After wrapping |
It can import to iReal 3D Mapping software to optimize the textures. |
Open Files or Project Files
Click to Open File or Open Project according to the file format. Before opening, please clear the data that is opening in iReal 3D Scanning software, otherwise, the Open button will be gray and cannot be used.
Project Characteristics
- The common characteristics of the scan project, point cloud project, and mesh project:
After saving, a folder with the specified name will be generated in the specified location.
Multiple files are contained in the folder.
Select the index file (. epj/. apj/. spj) when opening project files.
Scan Project
- .epj file:
Index file.
Scan projects usually have a relatively large amount of file data, which is not conducive to data transmission and sharing. If there are no special circumstances, it is not recommended to save.
Note
The scan project can be saved at any time during scanning, and it supports rescanning the object for the next time. The premise is that the object doesn’t have any deformation.
You can leave the site for processing data after saving the project files, but checking the data if it is complete is necessary.
Point Cloud Project
Folder directory structure: .apj file, .asc file and TextureImage folder.
It can generate 1 complete 3D model including the textures with 2 .asc project files using the tool of Model Alignment.
- .apj file:
Index file.
- .asc file:
The normal .asc file can be copied and opened in third-party software to warp as a .stl file.
- TextureImage folder:
The texture data is stored and can only be read by
iReal 3D. As long as this folder is there, iReal will try to paste the texture from the TextureImage file to the .asc file or .stl file when opening the .asc project file or .stl project file, even if the .asc and .stl are not the original source files.
Note
The biggest function of point cloud project is to do model alignment using 2 point cloud projects.
When the .asc is changed to .stl in the folder, the point cloud project has become a mesh project file. We can make the textures in
iReal 3D, but the premise is that the coordinates aren’t changed during the wrapping. Please refer to Map after repairing iReal 2E scanned model.
Mesh Project
Folder directory structure: .apj file, .asc file and TextureImage folder.
- .spj file:
Index file.
- .stl file:
The .stl 3D file can be regarded as a 3D model with a single color used for 3D printing and archiving. It also supports to be read and processed in third-party software, for example, importing .stl file to repair or sculpture 3D software to optimize data and save it as a file with the original in the original folder, then opening it in iReal 3D to recalculate the textures.
- TextureImage folder:
Same as a point cloud project.
