腾讯发布HY-World 2.0,推动世界模型从"预测像素"转向"构建场景"。该系统支持文本、图像、多视图或视频输入,通过分阶段流程输出包含几何、深度信息的持久3D资产(meshes和Gaussian splats),可导入Blender、Unity、Unreal或Isaac Sim编辑。WorldMirror 2.0可通过单次前向传播重建照片或视频,生成可导航的数字孪生。相比传统仅生成像素流的模型,HY-World 2.0构建真正可重渲染、可编辑的3D场景。
Another big step for World Model.
Tencent just released HY-World 2.0, a 3D world model that turns text, images, photos, and video into editable scenes instead of flat clips.
Most world models predict pixels, which looks fine from one view but often breaks when the camera moves or when you try to reuse the result as a real asset.
HY-World 2.0 tries to build the scene itself, recovering geometry, depth, camera pose, and renderable 3D assets, while WorldMirror 2.0 reconstructs photos or video in 1 feed-forward pass to produce a navigable digital twin.
What is happening here is that @TencentHunyuan is trying to move world models from “generate the next frame” to “build the place itself,” because HY-World 2.0 takes text, a single image, multiview images, or video and aims to output persistent 3D assets such as meshes and Gaussian splats, which are small soft 3D points that can be rendered quickly from new views.
That is a big deal because a video world model can look interactive while still being only a stream of pixels, while a real 3D asset can be re-rendered from new angles, edited later, and imported into tools like Blender, Unity, Unreal, or Isaac Sim.
HY-World does this with a staged pipeline in which HY-Pano 2.0 makes a panorama, WorldNav plans a camera path, WorldStereo 2.0 expands the world, and WorldMirror 2.0 composes the final 3D scene.
