Summary

TextHOI-3D is a novel staged framework designed for text-to-3D hand-object interaction, addressing challenges in preserving language semantics, cross-view consistency, object geometry, articulated hand shape, and physically plausible contact. This system uses generated multi-view observations as an explicit interface between text-conditioned visual generation and geometry-aware hand-object recovery. TextHOI-3D learns a compact VQ token space for fixed-camera hand-object observations, predicts multi-view visual tokens from text using a CLIP-conditioned visual autoregressive model, and then recovers a unified hand-object mesh through prior initialization, multi-view joint optimization, and anti-penetration refinement. On HO3D-derived evaluations, the multi-view setting significantly reduced object CD from 17.26 mm to 4.92 mm and penetration volume from 5.3721 cm^3 to 0.2193 cm^3, while improving hand errors and surface F-scores.

Key takeaway

For Computer Vision Engineers developing text-to-3D generation systems, this research highlights the critical role of multi-view intermediate representations. Your projects involving complex articulated objects like hands interacting with objects should consider integrating discrete multi-view token approaches. This method significantly improves geometric accuracy and physical plausibility, reducing object penetration and enhancing overall mesh quality, as demonstrated by the substantial reduction in CD and penetration volume.

Key insights

Multi-view visual tokens effectively bridge text-conditioned visual generation and geometry-aware 3D hand-object mesh recovery.

Principles

• Separate semantic generation from geometric recovery.
• Discrete multi-view representation connects generation and recovery.

Method

TextHOI-3D learns a VQ token space, predicts multi-view visual tokens from text via a CLIP-conditioned autoregressive model, then recovers a hand-object mesh through initialization, joint optimization, and anti-penetration refinement.
