Capturing a Surface Light Field Under Virtual Illumination

Surface light fields can be used to render the complex reflectance properties of a physical object. One limitation is that they can only represent the fixed lighting conditions of the environment where the model was captured. If a specific lighting condition is desired, then there are two options: either use a combination of physical lights as an approximation, or capture a full 6D surface reflectance field and only use the portion that corresponds to the desired lighting. In this paper we present a method for capturing a surface light field using the virtual illumination from an environment map. We use a simple setup consisting of a projector, a camera, a pan-tilt unit, and tracking fiducials to recreate the desired lighting environment. To decrease noise and improve the quality of the capture under lowand highdynamic range environment maps, we use an extended version of the multiplexed illumination algorithm. We show results from objects captured under different lighting envi-
