Replica

Replica is a dataset of 18 highly photo-realistic 3D indoor scene reconstructions released by Facebook Reality Labs in 2019. Each scene consists of a dense mesh, high-resolution HDR textures, per-primitive semantic class and instance information, and planar mirror and glass reflectors. The scenes span room and building scale, including apartments, offices, hotels, and retail spaces. Replica was designed specifically to support machine learning research that relies on visually, geometrically, and semantically realistic generative models of the world. It has been adopted as a core dataset in the Habitat simulation platform, where it provides high-quality 3D environments for navigation, interaction, and rearrangement tasks. With 1,300+ GitHub stars, Replica is a foundational dataset for egocentric computer vision, semantic segmentation, geometric inference, and embodied AI research, particularly in the Habitat ecosystem.
