Every generation of the Budget3D release galleries as 3D Gaussian splats: 200 objects, each generated by Budget3D-Idol (50 steps) and by Budget3D-Idol-Turbo (5 steps) at 100, 90, 80, 70, 60, 50, 40, 30, 20 and 10% of Idol's 8,192 latent tokens, from the same input image and the same noise at every budget. Eight of them, at 100 to 40%, are the splats behind the interactive viewer on the Budget3D page.

Unofficial, open-source implementation. These splats are part of BudgetAny, a community reimplementation and extension of the compute-adaptive tokenization idea of BudgetPix: Compute-Adaptive Tokenization for Pixel-Space Image Diffusion (Kara et al., 2026). They are not an official release of that paper, and BudgetAny is not a company or a lab. The paper covers pixel-space image diffusion only; applying the idea to image-to-3D is an extension made here. Thanks to the BudgetPix authors for the method.

Files

path	format	per file	for
ply/{model}/{object}/b{budget}.ply	standard 3D Gaussian Splatting PLY, 262,144 Gaussians, degree-0 colour	17.8 MB	any splat viewer or tool
spz/{model}/{object}/b{budget}.spz	SPZ (degree-0 colour)	about 2.7 MB	the web viewer

{model} is idol or turbo; {object} is one of the 200 names in objects.json; {budget} is 100, 090, 080, 070, 060, 050, 040, 030, 020 or 010.

102 of the objects (dome-*) were generated from single renders of Dome-Objaverse (CC BY 4.0), multi-view renders of Objaverse objects; the others from the galleries' own input images. objects.json gives the source of each.

The PLY files are Idol's own output format, with y pointing down (most viewers turn such files 180 degrees about x). The SPZ files are already upright (y up) and leave out the Gaussians below 1/255 opacity, the same ones the page's renders leave out.

How they were made: the latents kept by the release galleries (the same samples as the page's videos and frames) were decoded with Idol's unchanged decoders, with the decoder's anchor sampling seeded the same way at every budget, and the SPZ files were written with Spark's encoder (transcodeSpz, Spark 2.4.0).
