1. A system for generating and displaying a modeled appearance of a surface of interest on an electronic visual display device, the system comprising:
- a display device;
an illumination sensor;
an orientation sensor adapted to sense at least one of the roll, pitch or yaw of the display device; and
a processor in communication with the illumination sensor, the orientation sensor and the display device, the processor programmed to;
derive an ambient illumination condition of one or more real illumination sources for the display device from an output of the illumination sensor;
derive an orientation of the display device from an output of the orientation sensor; and
generate modeled appearance data for the surface of interest based at least in part on an average BRDF of the surface comprising a color selected from a pre-existing color library, the ambient illumination condition of the display device, and on the orientation of the display device;
wherein the display device receives modeled appearance data for the surface of interest from the processor and displays the modeled appearance of the surface of interest.

Abstract
A processor-based device for displaying simulated or modeled surface appearances based on surface color and surface texture data stored in a data storage. By selecting different combinations of color and texture, different surface appearances may be modeled and displayed. Also, the device may comprise an orientation sensor. Accordingly, the device may additionally consider the orientation of the device when generating surface appearances.
