Description
Hi,
thanks for your amazing work! I have a potentially silly question to ask. I need to access the 2D bounding-boxes for each camera (front, left, right, back) but I could only find the bounding-boxes for the equirectangular image. I access the 2d boxes with:
token = "'tr1thGb4-HK8yPOzSZFHQQ-cam-front"
boxes = met.get_sample_data(token, get_all_visible_boxes=False)[2]
The result is a list of EquiBox2d. Do they refer to the projection of the bounding-boxes onto a specific camera (e.g., the frontal one)?
My second questions regards the content of the points attribute. It's a numpy list of shape (80x2). Are these all the points of the bounding box (and in this case, the four corners are the actual coordinates of the bounding box)?
Thanks in advance! :)

Research direction
Start at met.get_sample_data(...) and inspect the returned EquiBox2d objects, especially points, for the cam-front token and the other camera names mentioned. Done means determining whether the boxes are camera-specific and what the (80, 2) points represent; no target file or test is named in the issue.
