GlobalSplat — pretrained weights

Feed-forward, generalizable 3D Gaussian Splatting via global scene tokens (align first, decode later). These are the released RealEstate10K checkpoints for the GlobalSplat paper.

Checkpoints

File	Variant	#Gaussians	RE10K 24-view PSNR / SSIM / LPIPS
globalsplat-re10k-2k.ckpt	2K (M_max=2)	2K	26.84 / 0.838 / 0.199
globalsplat-re10k-16k.ckpt	16K (paper default)	16K	28.53 / 0.883 / 0.140
globalsplat-re10k-16k-noopacity.ckpt	16K (current code, no opacity loss)	16K	28.95 / 0.891 / 0.124
globalsplat-re10k-32k.ckpt	32K	32K	29.48 / 0.901 / 0.123

The -noopacity 16K (trained with the released code, decoder opacity regularizer disabled) outperforms the paper default at every context count: 12v 29.10 / 24v 28.95 / 36v 28.76 PSNR.

All files are weights-only checkpoints (state_dict + Lightning version; the frozen VGG perceptual net and optimizer state are stripped).

Usage

With the GlobalSplat code:

# 16K paper default
python -m globalsplat.main +experiment=re10k_16k dataset=re10k_eval_ctx24 \
    mode=test checkpointing.load=globalsplat-re10k-16k.ckpt
# 2K (sets M_max=2) and 32K
python -m globalsplat.main +experiment=re10k_2k  ... checkpointing.load=globalsplat-re10k-2k.ckpt
python -m globalsplat.main +experiment=re10k_32k ... checkpointing.load=globalsplat-re10k-32k.ckpt
