Quads in 3D visualization is a process of creating three-dimensional images from two-dimensional images. This process is often used to create models of objects, buildings, or landscapes. Quads can be used to create photo-realistic images or illustrations. The process usually involves taking multiple photos from different angles and then using software to stitch them together.
Quads can be used for a variety of purposes, such as creating virtual tours, product demonstrations, or educational simulations. They can also be used for marketing and advertising purposes. Quads can be created from scratch or by using existing photos. Often, a combination of both methods is used.
