As a result of the significant advancement of graphics hardware and image rendering algorithms, 3D computer graphics capability has become available even on low-end computers. However, it is often the case that 3D object models are created manually by users. That input process is normally time-consuming and can be a bottleneck for realistic image synthesis. Therefore, techniques to obtain object models automatically by observing real objects could have great significance in practical applications. For generating realistic images of a 3D object, two aspects of information are necessary: the object's shape and its reflectance properties such as color and specularity. A number of techniques have been developed for modeling object shapes by observing real objects. However, attempts to model reflectance properties of real objects have been rather, |
