Abstract

We are interested in measuring the volumetric scattering phase function of materials. While previous approaches have relied on computationally costly inverse rendering optimization, we suggest a simple closed-form approach, for acquiring scattering phase function from thick samples. We have built a prototype capable of measuring phase functions over a narrow angular cone. We test our approach using validation materials whose phase function is known; and we use it to capture a set of everyday materials.
