Realism in computer-generated images requires accurate input models for lighting, textures and BRDFs. One of the best ways of obtaining high-quality data is through measurements of …
Our world consists not only of objects and scenes but also of materials of various kinds. Being able to recognize the materials that surround us (eg, plastic, glass, concrete) is …
It is easy to visually distinguish a ceramic knife from one made of steel, a leather jacket from one made of denim, and a plush toy from one made of plastic. Most studies of material …
