3D vs. 4D: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 28, 2023
3D refers to three-dimensional space, incorporating height, width, and depth, while 4D adds the dimension of time or temporal change to 3D space.

Key Differences

3D represents three spatial dimensions: height, width, and depth, creating a sense of physical reality in images or objects. In contrast, 4D builds upon 3D by incorporating time as a fourth dimension, often used in dynamic simulations or experiences.
3D is widely used in computer graphics, architecture, and film to create lifelike representations. 4D extends these representations by adding movement or change over time, as seen in 4D cinema experiences or complex scientific visualizations.
In 3D printing, objects are created in three dimensions, offering tangible models. 4D printing introduces materials that change shape or function over time when exposed to external stimuli, like heat or water.
The concept of 3D is easier to visualize and is commonly experienced in everyday life, from sculptures to video games. 4D concepts, while rooted in 3D, require a more abstract understanding, often linked to time-based processes or changes.
Virtual reality often uses 3D for immersive environments, while augmented reality can use 4D to overlay time-based data or changes onto the real world, enhancing user interaction with both spatial and temporal elements.
