One of the potential outputs of 3D graphics is called realistic 3D. It is a technique that attempts to generate a realistic visual representation where the output is hard to distinguish from reality. It involves the use of accurate modeling techniques, photorealistic materials and textures. In the end, the final illumination faithfully copies the rules and phenomena of real-life light spreading. The result is an image that cannot be distinguished from the real photo and can be used in a number of fields.

The development of new technologies in all areas overlapping the process of 3D creation is conducive to the process of realistic 3D creation. It may involve accurate modeling tools or the newest algorithms of illumination calculation.
