What is ReplicaCAD?

Vist the ReplicaCAD Homepage

The ReplicaCAD dataset is an artist recreation of the scanned “FRL apartment” variations from the Replica dataset. This dataset is intended for use in the Habitat simulator for embodied in-home interaction tasks such as object re-arrangement.

Dataset Contents:

We provide two dataset downloads with different properties: one suited to interactive simulation and the other for photorealistic visualization.

Note: Both downloadable datasets contain 84 of the 105 variations described in the paper and shown in the video with the remaining 21 scenes (1 macro variation and associated 20 micro variations) withheld as a test set for challenge evaluation.

ReplicaCAD Interactive:

Intended for use with a PBR shader. Contains 1 empty scene and 6 re-creations of the scanned “FRL apartment” variations staged with both large furniture and small objects and ready for dynamic simulation in Habitat-sim. Also included are 84 (of 105) artist authored re-arrangements of large furniture (fully static placements except articulations) organized into 5 macro variations (as different tenants may organize the same apartment) each with an additional 20 micro variations (with a few pieces of furniture moved/swapped).

ReplicaCAD with baked lighting (this repository):

[525MB]

Contains the same 84 (of 105) artist authored re-arrangements of large furniture described in ReplicaCAD Interactive with synthetic global illumination baked into the textures for more photo-realistic visualization. All articulated furniture is included with baked lighting textures, but all other furniture is static.

84 stage (i.e., static background) assets with baked light color textures
6 URDF assets with baked light color textures
1 SceneDataset configuration file which aggregates all config and asset paths for one-line import in Habitat.
.navmesh files (in navmeshes/ directory) for every scene computed for an agent with 0.3m radius (e.g. appropriate for a Fetch robot base) and additional .navmesh files (in navmeshes_default/ directory) computed with Habitat default agent parameters for optional use.
84 Habitat SceneDataset configuration files defining the placement of the articulated objects within the stages. Also includes global receptacle metadata in world space equivalent to local receptacle metadata from ReplicaCAD interactive. References the Fetch tuned NavMeshes.
