Homonym: 3, D (Three-Dimensional)
"3D" stands for "three-dimensional," which refers to objects that have depth, width, and height. Unlike two-dimensional (2D) images, which only have height and width, 3D objects can be viewed from multiple angles, making them appear more realistic. This concept is widely used in various fields, including art, design, and technology.
In the realm of technology, 3D modeling and printing have gained popularity. 3D modeling involves creating a digital representation of an object, while 3D printing allows for the physical creation of that object using materials like plastic or metal. These advancements have transformed industries such as manufacturing, healthcare, and entertainment.
