Understanding the Z-Axis in 3D Space

The z-axis is a concept in three-dimensional (3D) space that extends from the origin of the coordinate system to some specified distance along the axis. It is one of the three axes that define the orientation and position of an object in 3D space, along with the x-axis and y-axis.

In computer graphics and other fields, the z-axis is often used to represent depth or distance from the viewer. Objects that are closer to the viewer are represented by positive values on the z-axis, while objects that are farther away are represented by negative values. This allows for the creation of 3D scenes with layers of objects at different distances from the viewer, creating a sense of depth and perspective.

In addition to its use in computer graphics, the z-axis is also used in other fields such as engineering, physics, and mathematics to describe the orientation and position of objects in three-dimensional space.
