length width depth 3D shapes have different properties to 2D shapes. Faces - A face is a flat surface on a 3D shape. Edges - An edge is where two faces meet. For example a cube has 12 edges.

One of the works spotlighted is Mesh R-CNN, a method that’s able to predict three-dimensional shapes from images of cluttered and occluded objects. Above: Mesh R-CNN converts 2D objects to 3D ...

In this research, we are focused on one part of that challenge: how we can get AI to accurately recognize 3D objects -- such as people or cars -- in 2D images, and place those objects in space." ...

Two-dimensional (2D) shapes are completely flat. They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they ...
