Using a digital camera and importing photos to software

In a conventional production pipeline, you first use a digital camera to take the photos of the target object
and then use a photogrammetric modeling software to which you import the photos, process them and export the 3D model. To take photos,
you may use a smartphone's built-in camera, but using a stand-alone digital camera is recommended to make a model of a better qualtiy.

Here is a good small set of photos you can use for practice.
      Sample photos 18 photos of a sculpture at Boston MFA

Preparing good set of photos is most essential for making a good 3D model. This video is made by Atudesk for Recap Photo, but
it shows the basic photo taking method that applies to all photo-based scanning methods, so watch it first.

Also, at the end of your process, use the following guideline to appropriately size your model when you export it to your purpose.
      For Unity / Meta Quest HMD
            decimated mesh count max: 400,000-600,000 for the total of all models, Texture image max: 4096x4096 pixels (possibly multiple images)
      For Design Heritage website:
            decimated mesh count: 5,000-150,000 for each model, Texture image max: 4096x4096 pixels (single image)

Smartphone-based integrated hand-held scanning solution

Recent option for 3D scanning includes smartphone based integrated solution, where the app uses the phone's camera and/or LiDAR sensor (iphone).
It works like a hand-held scanner, without the process of exporting the photos to a separete processing software.
Amng many emerging apps available that you can find by Google'ing "3D scan smartphone app", here are a few examples available on app stores for those who are interested in testing.
These apps are capable of producing phogotrammetric 3D mesh models as well as 3D Gaussian Splatting models.
If you use one of these apps for Design Heritage platform upload, make sure that the app can export a model in obj format and with only one texture map image.
