3D imaging techniques are methods used to create three-dimensional representations of objects or environments. These techniques include stereoscopy, which uses two slightly different images to create depth perception, and laser scanning, which captures precise measurements of an object’s surface. Another common technique is computed tomography (CT), which combines multiple X-ray images taken from different angles to produce cross-sectional views. 3D modeling software can also be used to create digital representations of objects, allowing for visualization and manipulation in a virtual space. These techniques are widely used in fields like medicine, engineering, and entertainment.
