BioPhysGS research implementation and reproduction materials.
- Formal training/rendering source and the calibrated full-model Hamlyn snapshot.
- Exact custom rasterizer, nearest-neighbor and SSIM CUDA extension source.
- DroidCalib/DROID initialization/export source and fine-tuned Depth Anything V2 inference/training source.
- Explicit experiment profiles, image metrics, recorded numerical summaries and source provenance.
- English/Chinese installation and data preparation instructions.
- SHA256-checked initializer and fine-tuned ViT-B inference weights; optimizer state is omitted without changing inference tensors.
Validation: three independent CUDA extension builds, 600-step full/Hamlyn train-save-load-render-evaluate cycles and a depth inference pass on an RTX 3080. See provenance/release_validation.json for environment, scope and hashes. Initializer entry-point validation uses its recorded environment; full initializer rebuilding/tracking and all 30,000-step paper experiments are outside this release check.
