1. Choose a video below:

Input Video

2. Play around with the models: You can control the playback in both viewers at the same time by using the video, or control both viewers independently by using mouse and GUI!

3. Choose your favorite model for each criteria:

Global Appreciation Your overall appreciation of the models, including general aesthetics and self-contacts if applicable.

Ground Contacts The quality of the models' contacts with the ground, including ground penetration and foot sliding.

Fidelity The fidelity of the models compared to the motion of the original video.

Fluidity The smoothness and temporal coherence of the models.

Global Appreciation

Thank you for using the 3D Animation Arena!

This app is designed to compare different models based on human preferences, inspired by dylanebert's 3D Arena on Hugging Face. Current rankings often use metrics to assess the quality of a model, but these metrics may not always reflect the complexity behind human preferences.

The current models competing in the arena are:

4DHumans (https://github.com/shubham-goel/4D-Humans)
CLIFF (https://github.com/haofanwang/CLIFF)
GVHMR (https://github.com/zju3dv/GVHMR)
HybrIK (https://github.com/jeffffffli/HybrIK)
WHAM (https://github.com/yohanshin/WHAM)
CameraHMR (https://github.com/pixelite1201/CameraHMR)
STAF (https://github.com/yw0208/STAF)
TokenHMR (https://github.com/saidwivedi/TokenHMR)

All inferences are precomputed following the code in the associated GitHub repository. Some post-inference modifications have been made to some models in order to make the comparison possible. These modifications include:

Adjusting height to a common ground
Fixing the root depth of certain models, when depth was extremely jittery

All models use the SMPL body model to discard the influence of the body model on the comparison. These choices were made without any intention to favor or harm any model.

The videos were selected to tests models on a large variety of motions, don't hesitate to send me your videos if you want to have it uploaded in the arena! All matchups are generated randomly, don't hesitate to rate the same videos multiple times as the matchups will probably be different!

If you have comments, complaints or suggestions, please contact me at 3danimationarena@gmail.com. New models and videos will be added over time, feel free to share your ideas! Keep in mind that I will not add raw inferences from other people to keep it fair.
