This is a structured overview over ObjExImg’s user interface. For an introduction, please refer to How To.

Main Window

ObjExImg’s main window has two panes: The Images pane, where you choose the photos, select parameters and start the generation process, and the 3D Model pane, where you preview and export the generated 3D model. You toggle between the panes with the control in the upper right corner or the entries in the View menu (the 3D Model pane becomes available as soon as a model was generated).

Images Pane

In the Images pane you choose the folder containing the photos to be used for object reconstruction. Drag the folder here, or click the icon so select the folder with an open panel.
Once you selected a folder you can preview the contained photos.

Also in the Images pane are the main parameters, Detail Level, Object Masking, and Feature Sensitivity; see Parameters in the How to about these.

According to Apples documentation, the different detail levels will produce:

Level Faces* Map Size* Maps*
Preview 25.000 1024 × 1024 Diffuse, Normal, Ambient Occlusion
Reduced 50.000 2048 × 2028
Medium 100.000 4096 × 4096
Full 250.000 8192 × 8192 Diffuse, Normal, Ambient Occlusion, Roughness, Displacement
Raw 30.000.000 8192 × 8192 (multiple) Diffuse
Custom** Adjustable (click button next to detail menu)

*) up to: can be lower if source images do not provide a sufficient amount of data.
**) requires macOS 14 or later. Note that as of macOS 14.0, there is a minimum of 25.001 faces

Click Create 3D Model to start the reconstruction of the object.

3D Model Pane

The 3D Model pane lets you preview and export a generated model. Use the controls in the lower left to switch the primary interaction mode between Rotate, Move and Zoom (holding the Option key temporarily toggles) and to turn textures and the wireframe overlay on or off.

Use Export… to export the model and pick from one of the following formats:


Sequential Sample Ordering: If you provide the photos of an object in order, enabling this can result in higher performance. It has no impact on the quality of the generated model.

Scrolling lets you choose which action is performed in the 3D model preview by scrolling: Zoom or Move.

In addition, should you prefer SceneKit’s interaction model (like in Quicklook or Xcode), you may enable it here. You can also pick custom colours for the model pane background and untextured model.
