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.
