- Selecting multiple sets will display the intersection of all selected sets.
- Current Feats. are features visible from that camera pose.

Navigating the camera
- In first person POV:
  - Pan and zoom are disabled.
  - Upon rotation, the camera jumps from straight ahead to straight up. From there, simply rotate back towards the image plane.
Slower Internet Speeds
- Occasionally, playback speed surpasses Internet speed. Pausing the visualization for a moment should load the current image and the next few images.
- Alternatively, try loading the visualization without images, as loading the images takes a considerable amount of extra time.

Using the visualization offline (requires obtaining a copy of the website)
- Find your browser here and follow the instructions in order to get images to show up.
- Open index.html as you normally would with your browser.
No WebGL Support
- If you get an error message saying you do not have support for WebGL, you can likely enable it. Either Google search '<your browser name> enable WebGL' or, try using Chrome, which should have it enabled by default.
