3D point cloud vector interface

When creating a dataset through the Python SDK, choose pointcloud-vector or pointcloud-vector-sequence as the task_type to use this labeling interface
Tip: use your GPU in Chrome to make sure the 3D point cloud interface runs smoothly.

Create a new vector

You can create three types of vectors: a polygon, polyline, and a keypoint.

Create a polygon

  1. 1.
    Select the "Create polygon" tool by clicking on the polygon icon in the toolbar on the left, or by pressing the hotkey (g by default).
  2. 2.
    Click in the perspective or orthographic view to add a point to the polygon (each click adds a new point).
  3. 3.
    Close the polygon by
    1. 1.
      double clicking (this adds a final point and closes the polygon) or by
    2. 2.
      clicking on the first polygon point (this closes the polygon without adding a final point) or by
    3. 3.
      confirming the object (hotkey space by default) - this closes the polygon without adding a final point.

Create a polyline

  1. 1.
    Select the "Create polyline" tool by clicking on the line icon in the toolbar on the left, or by pressing the hotkey (n by default).
  2. 2.
    Click in the perspective or orthographic view to add a point to the polyline (each click adds a new point).
  3. 3.
    Close the polyline
    1. 1.
      by double clicking (this adds a final point and finishes the polyline) or by
    2. 2.
      confirming the object (press space hotkey by default) - this closes the polyline without adding a final point.

Create a point

  • Select the "Create point" tool by clicking on the point icon in the toolbar on the left, or by pressing the hotkey (p by default).
  • Click in the viewer to add a point.

Remove a vector

  1. 1.
    Select the vector you want to remove.
  2. 2.
    Press the hotkey (Backspace by default) or click the trash icon next to the object in the objects sidebar on the right.

Select a vector

Using the "Select and edit" tool

  1. 1.
    Select the "Select and edit" tool by clicking on the pointer icon in the toolbar on the left, or by pressing the hotkey (Esc by default).
  2. 2.
    Click on the vector in any view.

Using the objects sidebar

  1. 1.
    Click on the object in the objects sidebar to select it.

Translate a vector

  • Polygon. Hover over a polygon (the cursor changes to a "move cursor"). Click, hold and drag to move the polygon.
  • Polyline. Hover over a polyline (do not hover over the middle of a line segment, this adds a preview of a new polyline point - see Add a point to a vector). The cursor changes to a "move cursor". Click, hold and drag to move the polyline.
  • Point. Hover over a point (the cursor changes to a "move cursor"). Click, hold and drag to move the point.

Translate a vector point

Hover over a polygon point, a polyline point or a key point. The cursor changes to a "grab cursor". Click, hold and drag to move this point.

Add a point to a vector

  1. 1.
    Select a vector.
  2. 2.
    Hover over the middle of a line. A preview point is shown.
  3. 3.
    Click to add this point to the polygon or polyline.

Remove a point from a vector

  1. 1.
    Hover over a polygon or polyline point. The cursor changes to a "grab cursor".
  2. 2.
    Click to remove this point.

Change the category of a vector

Using the category dropdown

  1. 1.
    Select the vector.
  2. 2.
    Open the category dropdown by clicking on the category name in the objects sidebar on the right, or by pressing the hotkey (c by default).
  3. 3.
    Select a category by clicking on the desired category, or by using the arrow keys and pressing Enter to confirm.

Using the category hotkey

  1. 1.
    Select the vector.
  2. 2.
    Press the hotkey of the desired category (1 - 9).

Cycle between vectors / select the next vector

Press the hotkey (Tab by default).
