Homonym: 2D (Dimension)
"2D" stands for "two-dimensional," which refers to objects or images that have only two dimensions: length and width. This means that 2D shapes, like squares, circles, and triangles, do not have depth. They can be drawn on flat surfaces, such as paper or screens, and are commonly used in art, design, and animation.
In contrast to 3D (three-dimensional) objects, which have depth, 2D representations are often simpler and easier to create. Examples of 2D art include paintings, drawings, and digital graphics. Many video games also use 2D graphics to create engaging visual experiences without the complexity of 3D modeling.
