Abstract

In three-dimensional (3D) computer graphics, photography is treated not as the final product but as data to be extracted, information to be mapped onto and raw material to augment 3D models. Texture maps, normal maps and bump maps, created from photographic data, describe the reflectance properties of an object in a virtual scene. They give instructions to the render engine to calculate the correct pixel value, generating a near imperceptibly natural scene for the human eye. Computer graphics utilizes a network of images taken from different perspectives and at different scales to achieve photorealism. The project investigates one of many algorithmic visual systems that act as a backbone of virtual reality and gaming.
