Generation of representation of appearance of physical object under different diffuse lighting conditions involves combination of pixel signals obtained from virtual illuminations of model representation of object

摘要

Method for representing an illuminated physical object on a computer monitor or other output device includes selecting pixels of a predefined construction model (8). For each selected pixel (BP), a first light intensity (LIBP 1) resulting from a first illumination of the object is calculated. A second intensity (LIBP 2) resulting from a second illumination is calculated. The two intensities are combined to form an overall intensity (LIBP ges). This is converted to an input signal for the pixel which is processed by the output device. An object representation (9) is built up from these input signals. Independent claims are included for; (a) Image representation methods; (b) Data processing systems; and (c) Computer program products for automatic generation of a representation of an illuminated physical object.
