Helix4D: Complex 4D Mesh Generation 事件

Helix4D: Complex 4D Mesh Generation arXiv:2605.26109v1 Announce Type: new Abstract: Current video-to-4D methods struggle with complex topology changes, transparent materials, thin structures, and inner surfaces. We present Helix4D, a dynamic mesh generation framework by inheriting the expressive representation of Trellis2, adapting it from image-to-3D to video-conditioned 4D generation. Our design arises from two key questions: (a) how to enable Trellis2's frame-local attention to share informa
