Appearance Acquisition for Digital 3D Content Creation

Explore cutting-edge techniques for appearance acquisition in digital 3D content creation through this seminar talk by Sai Bi from UC San Diego. Delve into methods for recovering high-quality texture maps, reconstructing meshes with per-vertex BRDFs, and learning volumetric representations for joint view synthesis and relighting. Gain insights into RGB-D reconstructions, multi-view stereo, SVBRDF prediction, and mobile phone captures with flashlight. Discover the latest advancements in volumetric rendering, neural representations for scenes, and integration with physically-based renderers. Understand the challenges and solutions in reproducing the appearance of real-world objects and scenes for virtual and augmented reality applications.
