Hello! Thank you for signing up to be a beta user with Labelbox.
We will soon be releasing a cuboid labeling tool in our image editor that allows you to draw a cuboid (3D) shaped bounding box. This will allow you to capture the angles of objects as well, such as where a face is looking.
If you are interested in trying out this feature in our closed beta, please complete this short questionnaire and we will contact you as soon as possible with further instructions. Thanks!
