🪐 Objaverse-XL

This repository contains scripts to download and process Objaverse-XL.

Objaverse-XL is an open dataset of over 10 million 3D objects!

With it, we train Zero123-XL, a foundation model for 3D, observing incredible 3D generalization abilities: 🧵👇

Scale Comparison

Objaverse 1.0 was released back in December. It was a step in the right direction, but still relatively small with 800K objects.

Objaverse-XL is over an order of magnitude larger and much more diverse!

Unlocking Generalization

Compared to the original Zero123 model, Zero123-XL improves remarkably in 0-shot generalization abilities, even being able to perform novel view synthesis on sketches, cartoons, and people!

A ton more examples in the 📝 paper :)

Image → 3D

With the base Zero123-XL foundation model, we can perform image → 3D using DreamFusion, having the model guide a NeRF to generate novel views!

Text → 3D

Text-to-3D comes for free with text → image models, such as with SDXL here, providing the initial image!

Scaling Trends

Beyond that, we show strong scaling trends for both Zero123-XL and PixelNeRF!
