39: Acquiring Material Models Using Inverse Rendering



Tuesday, Half Day
8:30 am – 12:15 pm
Room 006AB

Recent work, relevant background information, and specific practical methods of capturing the appearance of materials from sets of photographs.

Prerequisites
Working knowledge of how materials are described for realistic rendering, including texture maps and the BRDF. Familiarity with shading and reflectance models and their use in rendering.

Topics
Methods for acquiring material properties from photographs. First session: inverse methods for determining material properties in complex scenes; inverse rendering in a signal-processing framework. Second session: capturing spatially varying BRDFs; estimation of BSSRDF and BTF models.
