What is Z-Axis?

The Z-axis is the third dimension of a three-dimensional (3D) coordinate system. It is perpendicular to the X- and Y-axes and typically represents depth or height. In 3D computer graphics, the Z-axis is used to control the camera’s position and viewing angle. By default, the camera is positioned at the origin (0,0,0) and faces down the negative Z-axis.

In 3D visualization, the Z-axis is often used to represent depth. This can be helpful when trying to understand the relationships between objects in a scene. For example, if you are looking at a two-dimensional (2D) map of a city, you might use the X- and Y-axes to represent the streets and buildings. However, if you were looking at a 3D model of the same city, the Z-axis could be used to represent the height of the buildings. This would give you a better understanding of the city’s layout and how the buildings relate to each other.
