The PS_Sculpture training dataset introduced by the PS-FCN [1] contains various non-Lambertian reflectances, cast shadows, interreflections and effective noise information. However, for dark materials such as black-phenolic and steel, significant data loss happens due to 8-bit quantification. To lessen this data loss, we design a new supplementary training dataset rendered by 10 blobby objects and 10 other objects freely downloaded from the Internet and the real BRDF data comes from the MERL dataset [2].
