Dataset

[+] 1001 unique shapes

[+] 295 material types with laboratory measured IOR

[+] 723 lighting conditions

[+] Physical based rendering with costomized BSDF for each material type

[+] 1001 uniques scenes, for each scene 90 images (50 for training, 40 for testing) with object mask, depth, camera pose, materail type annotations.
