Together with Ava-256, part of Codec Avatar Studio

We provide 4 sets of captures; for each subject:

• 1 relightable head capture
• 1 relightable hands capture
• 1 fully clothed capture
• 1 minimally clothed capture
• 1 mobile head capture
• 1 mobile hands capture
• 1 mobile fully clothed capture
• 1 mobile minimally clothed capture

And code to train personalized decoders:

• Relightable Gaussian Codec Avatar heads,
• Relightable hands
• Mesh-based bodies

Please refer to the samples to get a sense of what the data looks like.

Disclaimer

This is a pre-release.

Dependencies

See requirements.txt/environment.yaml

Repository structure

• ca_code/ - python source

  • loss - loss functions
  • models - standalone models
  • nn - reusable modules (layers, blocks, learnable, modules, networks)
  • utils - reusable utils (functions, modules w/o learnable params)

• notebooks/ - example notebooks

• extensions/ - CUDA extensions

• data/ - location of sample data and checkpoints

Data

Besides camera, views, we also provide segmentations, 3d keypoints, registered and unregistered meshes, as well as light information when available.

Access to the dataset is currently gated. Please email julietamartinez@meta.com, preferrably from an institutional email, to get access to the data.

Compiling and installing extensions

cd extensions/{mvpraymarch,sgutils,utils}
make
