Comparing appearances of fibers

摘要

A method and apparatus for assisting a user to compare appearances of fibers. The method comprises: providing (210) a computational model describing the interaction of light with fibers; obtaining (220) a first set of fiber parameters for use with the model, said first set of fiber parameters describing a first plurality of fibers; obtaining (620) a second set of fiber parameters for use with the model, said second set of fiber parameters describing a second plurality of fibers; simulating (240), using the model and the first set of fiber parameters, how light would interact with the first plurality of fibers, and rendering (250), based on the result of the simulation, a first synthetic image showing the appearance of the first plurality of fibers; simulating (640), using the model and the second set of fiber parameters, how light would interact with the second plurality of fibers, and rendering (650), based on the result of the simulation, a second synthetic image showing the appearance of the second plurality of fibers; and displaying (270, 670) the first synthetic image and the second synthetic image to the user.
