Preprocess Data

Data preprocessing consists of two parts, sdf preprocessing and camera-hand-object transformation preprcoessing.

Use our preprocessed data

We provide our preprocessed cache and mesh_sdf. These can be downloaded from here. You need to unzip it and put it under data/ folder.

Create your own cache data

Follow DeepSDF to generate SDF data mesh_sdf/. Modify this line fitToUnitSphere to False.

    float max_dist = BoundingCubeNormalization(geom, false);

The dataloader script will automatically generate cache if cache is not found.
