HY-World 2.0 Trajectory Renderer

HY-World 2.0 Trajectory Renderer

HY-World 2.0 Trajectory Renderer from Tencent (Hunyuan): camera-controlled-video and world-generation-stage; Runner parity pending.

Edit this pageGitHubMarkdown

HY-World 2.0 Trajectory Renderer is one stage of Tencent's world-generation chain, cataloged separately: it renders camera-controlled video from a pre-materialized HY-World scene point cloud (render_results/global_pcd.ply) along a camera JSON. It intentionally loads no model checkpoint — it is a renderer, not a generator.

What it is for

Use hyworld-worldgen to render camera-controlled video from an existing HY-World scene point cloud. It does not generate a scene or load a model checkpoint.

The adapter invokes the official trajectory-render stage from a local checkout at pinned revision 7f668e67c74338d50684e57be46a438459b6bbe1 (Tencent Hunyuan community license). The public tree does not bundle that source or implement the full five-stage world generation chain.

Catalog tasks include camera-controlled-video, world-generation-stage, and point-cloud-rendering. This route outputs a video from an existing point cloud.

Runtime contract

Optional input_path, height, width, seed, and camera_json; artifacts hyworld-worldgen.mp4.

CLI task profiles: default. WorldFoundry binds HYWorld2WorldgenPipeline.

Family status: Runner parity pending.

Provide an image, camera JSON, and a scene_path pointing at a pre-materialized HY-World scene. Scene materialization belongs to the separate full HY-World generation pipeline.

Before running, install the pinned official source in the runtime directory and provide a materialized scene containing render_results/global_pcd.ply. Neither asset is bundled with the public repository.

Running in WorldFoundry

Launch worldfoundry-eval run hyworld-worldgen after staging the source and scene to write video.

It runs in the unified environment worldfoundry-unified-cu128 (Python 3.11, CUDA 12.8).

This checkpoint-free renderer requires the official source checkout and a pre-materialized scene as described above.

Status: Runner parity pending.
