Radiance Scaling for Versatile Surface Enhancement
1 We present a novel technique called Radiance Scaling for the depic-2 tion of surface shape through shading. It adjusts reflected light in-3 tensities in a way dependent on both surface curvature and material4 characteristics. As a result, diffuse shading or highlight variations5 become correlated to surface feature variations, enhancing surface6 concavities and convexities. This approach is more versatile com-7 pared to previous methods. First, it produces satisfying results with8 any kind of material: we demonstrate results obtained with Phong9 and Ashikmin BRDFs, Cartoon shading, sub-Lambertian materi-10 als, and perfectly reflective or refractive objects. Second, it im-11 poses no restriction on lighting environment: it does not require a12 dense sampling of lighting directions and works even with a single13 light. Third, it makes it possible to enhance surface shape through14 the use of precomputed radiance data such as Ambient Occlusion,15 Prefiltered Environment Maps or Lit Sph...
