Abstract
A method of rendering a graphical object comprises accessing a mapping relating a mesoscale structure and a light scattering parameter of a material to a perceptual appearance characteristic; determining a perceptual appearance characteristic of the graphical object, the graphical object reproduced on an interface to represent an object formed from the material, the perceptual appearance characteristic determined in accordance with the mapping using an initial mesoscale structure and a light scattering parameter of the material; receiving a signal indicating a modification in structure relating to the initial mesoscale structure; and determining, using the mapping, an adjustment of the light scattering parameter preserving the determined perceptual appearance characteristic, based on the modification of the initial mesoscale structure. The method further comprises adjusting the light scattering parameter of the material according to the adjustment; and rendering the graphical object using the modified mesoscale structure and the adjusted light scattering parameter.
