  abstract = {We introduce a new set of illumination basis functions designed
              for lighting bumpy surfaces. This lighting includes shadowing and
              interreflection. To create an image with a new light direction,
              only a linear combination of precomputed textures is required.
              This is possible by using a carefully selected set of steerable
              basis functions. Steerable basis lights have the property that
              they allow lights to move continuously without jarring visual
              artifacts. The new basis lights are shown to produce images of
              high visual quality with as few as 49 basis textures. },
