Testing spatial patterns for acquiring shape and subsurface scattering properties
(read important copyright information before downloading) ,
Models of both the shape and material properties of physical objects are needed in many computer graphics applications. In many design applications, even if shape is not needed, it is desirable to start with the material properties of existing non-planar objects. We consider the design of a system to capture both shape and appearance of objects. We focus particularly on objects that exhibit significant subsurface scattering and inter-reflection effects.
We present preliminary results from a system that uses coded light from a set of small, inexpensive projectors coupled with commodity digital cameras.
