Stitching Two or More 3D Models

What is stitching?

Stitching is the manual combination of two or more Matterport 3D models into one large, combined model. Because this is a manual, time-intensive process, users must request this feature from our support team

When is stitching appropriate? 

You can request stitching for the following reasons: 

  1. You want visitors to be able to virtually walk from the scanned property to another scanned property nearby.
    • Example: Customer scans the inside of a house with a Matterport Pro2 camera, and the outside of the house with a BLK360. Customer then requests that the user can virtually move from the inside of the property to a detached garage in the backyard. 
  2. You want to use the 3D mesh created outside of the property. 
    • Architecture and engineering professionals often use the 3D mesh of their environment as a framework to create new environmental renders - unfortunately, the majority of outdoor images (especially in direct sunlight) are 360° snapshots, and thus do not have an associated mesh created. 
    • Users can bypass this caveat by scanning outdoors during the "golden hour" - more on this below. 
  3. Your model was not scanned correctly and several alignment points are broken. 
    • Example: The camera position changed height throughout the shoot, making for an awkward and/or inconsistent guided tour. 
  4. You scanned a 3D model with too many scan points (over 200), and you need Matterport to combine them into a single workable 3D model. 

The stitching process 

Cost 

Currently, stitching is a free service offered by Matterport. To request stitching for your 3D models, please contact our support team. Include the URLs for all of the models that you want combined.

Timeframe 

Stitching is a manual, time-intensive process that typically takes 20 working hours or more per project (in the best of situations). Because this is a time-intensive process, stitch requests have turnaround times of four weeks from when you submit the request.

Limitations

Any edits you make to the original model (such as Mattertag Posts) do not carry over to the combined model. Please wait to make those edits until after the stitching is complete.

Workarounds 

Use Deep Links with Mattertags

You can use Mattertags to link to other aspects of your 3D model, or to entirely different 3D models altogether. So if you want to move a user from the house they're touring to the shed in the backyard, you can create a Mattertag that will "transport" the user there with the click of a button. Learn more.

How is this different from stitching?

Deep links will "transport" users from one 3D model to another - like clicking a button to move from the bottom of a staircase to the top of a staircase - this eliminates the process of the user having to actually "walk up the stairs". This can be used to transport users to any part of an existing model, or a new model altogether.

Adversely, stitching allows users to actually "walk" from one point to another in one uniform model. This also means that dollhouse and floor plan views are fully rendered instead of being separate models.

Scan during the golden hour

If scanning outside is your goal, then scan during the 'golden hour' - this is 30 minutes before sunrise, or 30 minutes after sunset. During this time you will have enough light to take good pictures, but will have less infrared red to interfere with alignment measurements.
