Cuboid3D

class scenebox.models.annotation.Cuboid3D(label=None, uid=None, confidence=None, attributes=None, tl1=None, bl1=None, tr1=None, br1=None, tl2=None, bl2=None, tr2=None, br2=None, category_id=None)

Holds the coordinates and metadata of a Cuboid in three-dimension.

Several Cuboids can be compiled together to form a Cuboid3DAnnotation. Cuboids are made of two squares specifying the front and back of the object. Connecting lines are drawn between the vertices of the squares to form a cuboid.
