3D images are visual representations that create the illusion of depth, making them appear more lifelike than traditional 2D images. They are often created using specialized software or techniques that simulate how our eyes perceive the world. This depth perception is achieved by displaying two slightly different images, one for each eye, which the brain combines to form a three-dimensional view. These images are commonly used in various fields, including virtual reality, video games, and medical imaging. Technologies like stereoscopy and 3D modeling help produce these images, enhancing user experiences and providing detailed visual information in a more engaging way.
