View and navigate in the 3D interface

Tip: use your GPU in Chrome to make sure the 3D point cloud interface runs smoothly.

Move the camera

Hold the hotkey (Ctrl/cmd by default) and click and drag, or simply click and drag the right mouse button.

Only in the perspective view

  • Use the keyboard navigation (by default: w to move forward, a to move left, s to move backward, d to move right, Shift + W to move up, Shift + S to move down).

Rotate/orbit the camera in the perspective view

Hold the hotkey (Shift by default) and click and drag.

Set the rotation point

  • The rotation point is initialized at the center of the point cloud.
  • If you zoom to an object, the rotation point will move to the center of that object.
  • You can manually set the rotation point by middle-clicking on any point of the point cloud. The changed rotation point will then be visible for a short time.

Zoom in/out

To zoom in or out, scroll using the mouse wheel.

Zoom to an object

  1. 1.
    Select the object.
  2. 2.
    Press the hotkey (t by default).

Hide objects

Hide/show a single object

  1. 1.
    Hover over the object you want to hide/show in the objects sidebar.
  2. 2.
    Press the eye icon.

Hide/show all unselected instances

Press the hotkey (h by default).

Pan to a bird's eye view in the perspective view

Press the hotkey (Ctrl/cmd + b by default).

Enable intensity coloring

  1. 1.
    Upload a point cloud with intensity labels.
  2. 2.
    Click/hover over the sun icon in the toolbar on the right and select "Enable intensity coloring".
  3. 3.
    Optional: Choose a gradient by clicking on the gradient and selecting one from the list. You can also reverse the gradient by checking the box under "Reverse".

Change the size of the points

  1. 1.
    Click/hover over the dot icon in the toolbar on the right.
  2. 2.
    Drag the slider to adjust the point size.

Change the point budget

If you are labeling a point cloud with a large number of points (> 500K) and you notice lag when navigating around the point cloud, you can choose to change the point budget. The point budget controls the maximum number of points that are displayed. If the point cloud contains more points than the point budget, the point cloud will be randomly subsampled to limit the number of points.
  1. 1.
    Click/hover over the dot icon in the toolbar on the right.
  2. 2.
    Enter the maximum amount of points in the point budget input box. If you want to remove the point budget, simply remove the value in the input box.
This feature is only available in the 3D point cloud cuboid interface.

Change the key pan speed

  1. 1.
    Click/hover over the tachometer icon in the toolbar on the right.
  2. 2.
    Drag the slider to adjust the key pan speed, i.e. the speed the camera moves when using keyboard navigation.

View synced camera images

If you uploaded one or more camera images to your sample, you can view them directly in the interface, or in a separate browser tab (which you can e.g. move to a second screen).
  • Toggle the synced images in the interface by clicking on the image icon in the right toolbar, or by pressing the hotkey (q by default).
  • Display the synced images in a separate tab by holding Ctrl/Cmd and clicking the image icon in the right toolbar, or by right-clicking the image icon and click "Open in new tab" or "Open in new window".
When viewing the synced images, you can enlarge them as follows:
  • To zoom in on a synced image, double-click the image.
  • To move the zoomed-in image, click and drag on the image.
  • To reset the zoom of an image, double-click the image again.

Display a camera image behind the point cloud

If you uploaded one or more calibrated camera images to your sample, you can display a calibrated camera image behind the point cloud in the main point cloud viewer.
  1. 1.
    View the synced images.
  2. 2.
    Hover over the image you want to display in the main viewer. A camera button pops up in the top right of the image.
  3. 3.
    Press the camera button.

Change a side view

  1. 1.
    Click the dropdown in the top right corner of the side view.
  2. 2.
    Select the new view you want to change to.
This feature is only available in the 3D point cloud segmentation interface.
