8) Mark Windows, Mirrors, & Trim (ūüéě Video)

For a great user experience, it is CRITICAL to add mirror, window, and trim markings to your model. 

Mark features immediately after every scan. This reduces alignment issues and improves the quality of your finished Matterport Space.

For your first model with only two scans, marking features is not necessary. However, please bookmark this article for future reference.

 

 

Mirrors

The Matterport camera does not see a mirror the same way a human does. Remember, the camera uses infrared light to collect 3D depth data. Because mirrors reflect infrared light too, the camera will see the reflection and believe there is a room on the other side of the mirror. This is wrong and can cause alignment issues.

When you make a mirror marking, you are telling the Capture app to ignore what it sees on the other side of the mirror. This addresses the issue so you can scan normally. 

Avoid alignment issues by immediately marking mirrors as soon as the camera can see them.

Tap the Mark Features button in Capture. 

 Tap Mirror.

In the preview pane, tap one edge of the mirror, drag to the other edge of the mirror, and then release.

UI Controls:

  • To remove, tap the middle of the marking and then Delete.
  • To extend or rotate, tap or drag the endpoint as desired.
  • Tap and drag the middle to move the entire marking.
  • Use the pinch-and-zoom gesture to zoom in and out on the model and better place the marking.
Best Practices:
  • Make sure the ‚ÜĎ Front¬†label points to the inside of the room. To change the orientation, tap the middle of the marking, then Swap Label.
  • Place the marking¬†on the wall or slightly outside the wall. Exact placement is not necessary. However, if the marking is too far¬†inside then part of the 3D model (Dollhouse View) might be cut off.
  • For best results, extend your marking slightly longer than the actual mirror on the minimap. Make sure the marking¬†does not cover a¬†door or hallway.
  • For walls with multiple mirrors, you can make one long marking that covers all of the mirrors.¬†
  • Learn more¬†about best practices with mirrors.
Do not mark windows and mirrors above doorways. Window and mirror markings create an ‚Äėinvisible wall' that impedes movement in the 3D Space.

 

Windows

The Matterport camera doesn't see a window the same way a person does. Since it can see through the window, it attempts to collect 3D data and create a model of what it sees outside.

When you mark a window, you are telling the Capture app to ignore what it sees outside such as the grass, a tree, a parked car, etc. This makes for a nice, clean, and finished 3D Space (Dollhouse View).

You only need to mark windows that look out to areas that are not part of the model. You can mark interior glass walls for a stronger separation between rooms, but it is not necessary.

Tap the Mark Features button in Capture. 

 Tap Window.

In the preview pane, tap one edge of the window, drag to the other edge of the window, and then release.

UI Controls:

  • To remove, tap the middle of the marking and then Delete.
  • To extend or rotate, tap or drag the endpoint as desired.
  • Tap and drag the middle to move the entire marking.
  • Use the pinch-and-zoom gesture to zoom in and out on the model to better place the marking.
Best Practices:
  • Make sure the ‚ÜĎ Inside label points to the inside of the building. To change the orientation, tap the middle of the marking, then Swap Label.
  • Place the marking on the wall or slightly outside the wall. Exact placement is not necessary. However, if the marking is too far¬†inside then part of the 3D model (Dollhouse View) might be cut off.
  • For best results, extend your window marking slightly longer than the actual window on the preview.¬†Make sure the marking¬†does not cover a¬†door or hallway.
  • For a wall full of windows, you can make one long marking¬†that covers all the windows.
Do not mark windows and mirrors above doorways. Window and mirror markings create an ‚Äėinvisible wall' that impedes movement in the 3D Space.

 

Trim

The trim tool eliminates unwanted 3D depth data just like cropping for two dimensional images.

Any 3D data outside the trim marking will not appear in Dollhouse View or Floorplan View. This is important to clean up the Dollhouse View so it does not contain artifacts or jagged edges.

Trimming is usually not necessary if you have been correctly marking windows and mirrors along the way.

Tap the Mark Features button in Capture. 

 Tap Trim.

In the preview pane, tap where you want the marking to start, drag to the end, and then release.

Make sure the ‚ÜĎ Remove¬†label points to the unnecessary 3D data. To change the orientation, tap the middle of the marking, then Swap Label.

  • To remove, tap the middle of the marking and then Delete.
  • To extend or rotate, tap or drag the endpoint as desired.
  • Tap and drag the middle to move the entire marking.
  • Remember you can use the pinch-and-zoom gesture to zoom in and out on the model and better place the marking.
For walls, trim just outside and not directly on the wall. You might trim the wall out of the model.
