Abstract
The present invention provides a method of digitally generating, via the use of a computer, data indicative of a synthesized appearance of a simulated material having physically plausible appearance attributes. The method includes determining a set of data indicative of the synthesized appearance of the simulated material based at least in part on data associated with the physically tangible source material and at least in part on data of measured attributes of the physically tangible reference material.
Claims28
A method of digitally generating, via a computer, data indicative of a synthesized appearance of a simulated material having physically plausible appearance attributes, with the synthesized appearance being based on a physically tangible reference material and at least one value of a selected appearance attribute of a physically tangible source material different from the reference material, comprising the steps of:
- (a) accessing, via the computer, a first set of data indicative of the values of measured appearance attributes of the reference material, with the measured appearance attributes being measured at a plurality of locations on the reference material and for a plurality of illumination directions or a plurality of viewing directions relative to each of the locations;
- (b) accessing, via the computer, a second set of data indicative of a value of at least one measured appearance attribute of the source material, wherein the appearance attribute of the source material includes at least one, but not all, of the appearance attributes being measured on the reference material;
- (c) determining, via the computer, a third set of data indicative of the synthesized appearance of the simulated material based at least in part on data from the second set of data associated with the physically tangible source material and at least in part on data from the first set of data of measured appearance attributes of the physically tangible reference material different from that of the second set of data;
- and
- (d) displaying an image generated from the third set of data of the synthesized appearance of the simulated material.
A system for digitally generating data indicative of a synthesized appearance of a simulated material having physically plausible appearance attributes, with the synthesized appearance being based on a physically tangible reference material and at least one value of a selected appearance attribute of a physically tangible source material different from the reference material, the system comprising:
- (a) memory for storing a first set of data indicative of the values of measured appearance attributes of the reference material, with the measured appearance attributes being measured at a plurality of locations on the reference material and for a plurality of illumination directions or a plurality of viewing directions relative to each of the locations;
- (b) an instrument for measuring at least one appearance attribute of the source material and generating a second set of data indicative of a value of the measured appearance attribute, wherein the appearance attribute of the source material includes at least one, but not all, of the appearance attributes being measured on the reference material;
- (c) a computer configured to receive the first and second sets of data and configured to determine a third set of data indicative of the synthesized appearance of the simulated material based at least in part on data from the second set of data associated with the physically tangible source material and at least in part on data from the first set of data of measured appearance attributes of the physically tangible reference material different from that of the second set of data;
- and
- (d) a display in communication with the computer.
