Tencent’s HY-World 2.0 generates persistent 3D assets from text, images, or video using a four-stage pipeline. It outputs editable worlds compatible with Blender, Unity, and Unreal Engine.
NAS3R enables self-supervised 3D geometry and camera parameter estimation without ground-truth data, using Gaussian splatting and a VGGT backbone. It supports multi-view setups and optional pretrained initialization.
WorldGrow generates infinite 3D worlds via hierarchical block-wise synthesis with coarse-to-fine refinement, ensuring seamless, explorable environments for navigation and planning tasks.
