Z-axis

The Z-axis refers to the depth dimension in a three-dimensional (3D) design or coordinate system. Unlike the X and Y axes, which represent the horizontal and vertical planes respectively, the Z-axis extends perpendicularly into or out of the plane of the design. This additional axis allows for the representation of depth, giving objects in 3D space their spatial relationships and volume. In graphic design, 3D modeling, and animation, the Z-axis plays a crucial role in creating realistic environments and effects by enabling objects to be positioned not just on a flat plane but also in a depth-representative space. Understanding the Z-axis is essential for creating immersive and dynamic visual content.
