Run a demo

See installation for the CUDA environment, then:

python -m physstudio fetch bread
python -m physstudio run enlivening bread --gpu 0

Use --frames 12 --width 640 for a quick preview and --output for a custom run directory. Use --dry-run to print the launcher's exact commands. Pretrained models are downloaded separately; asset links and project credits are collected in the repository.
