What makes 3D differ from 2D is depth?

2D and 3D refer to the actual dimensions in a computer workspace. 2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension.

How do we distinguish between 2D and 3D objects?

A two-dimensional structure has only two surfaces; length and breadth. A three-dimensional structure has three surfaces; length, breadth, and height. Two-dimensional figures are also referred to as “plane” figures or “flat” figures due to their appearance. Three-dimensional figures are only referred to as 3D figures.

Do 2D shapes have depth?

2D shapes are shapes with two dimensions, such as width and height. An example of a 2D shape is a rectangle or a circle. 2D shapes are flat and cannot be physically held, because they have no depth; a 2D shape is completely flat.

What is depth in a 3D object?

In geometry, a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height. Unlike two dimensional shapes, three-dimensional shapes have height, which is the same as thickness or depth.
