Need to rig 3D models? 🦖

New work from UCSD and Adobe:
"RigAnything: Template-Free Autoregressive Rigging
for Diverse 3D Assets" Liu et al.

tl;dr: reduces rigging time from 2 mins to 2 secs, works on any shape category & doesn't need predefined templates! 🚀

"Latent Radiance Fields with 3D-aware 2D Representations" Zhou et al., #ICLR2025

tl;dr: Novel framework that integrates 3D awareness into VAE latent space using correspondence-aware encoding, enabling high-quality rendered images with ~50% memory savings.

"EdgeRunner" (#ICLR2025) from #Nvidia & PKU introduces an auto-regressive auto-encoder for mesh generation, supporting up to 4000 faces at 512³ resolution. 🤩

Their mesh tokenization algorithm (adapted from EdgeBreaker) achieves ~50% compression (4-5 tokens per face vs 9), making training efficient.
