Rendering-Aware Sparse Sampling for BRDF Acquisition 事件

Rendering-Aware Sparse Sampling for BRDF Acquisition arXiv:2604.26740v2 Announce Type: replace Abstract: Accurate BRDF acquisition is essential for realistic rendering, but dense gonioreflectometer measurements are slow and expensive. We study how to select a small set of BRDF measurements that is most informative for reconstructing material appearance under a learned BRDF prior. Existing sparse-acquisition methods often optimize samples for BRDF-space reconstruction for all materials, while th
