In this paper we describe our efforts to create a surface display system that produces realistic representations of real-world surfaces. Our system, based on a desktop PC with GPU hardware, LCD display, light and position sensors, and custom graphics software, supports the photometrically accurate and visually realistic real-time simulation and display of surfaces with complex color, gloss, and textural properties in real-world lighting environments, and allows users to interact with and manipulate these virtual surfaces as naturally as if they were real ones. We explain the system design, illustrate its capabilities, describe experiments we conducted to validate its fidelity, and discuss potential applications in material appearance research and computer-aided appearance design.

(a) (b) Paper BSDF Photograph Figure 1: A back-lit origami bird rendered with our Paper BSDF at varying paper thicknesses: (a) 0.05mm, (b) 0.26mm (our measured parameter for matte paper). On the right, a comparison between a photograph (right side) and our Paper BSDF for matte paper (left side). The scene is of an illuminated checkerboard pattern with matte paper placed in front of it. AbstractWe present a novel appearance model for paper. Based on our appearance measurements for matte and glossy paper, we find that paper exhibits a combination of subsurface scattering, specular reflection, retroreflection, and surface sheen. Classic microfacet and simple diffuse reflection models cannot simulate the double-sided appearance of a thin layer. Our novel BSDF model matches our measurements for paper and accounts for both reflection and transmission properties. At the core of the BSDF model is a method for converting a multi-layer subsurface scattering model (BSSRDF) into a BSDF, which allows us to retain physically-based absorption and scattering parameters obtained from the measurements. We also introduce a method for computing the amount of light available for subsurface scattering due to transmission through a rough dielectric surface. Our final model accounts for multiple scattering, single scattering, and surface reflection and is capable of rendering paper with varying levels of roughness and glossiness on both sides.
