HunyuanWorld-Mirror is a versatile feed-forward model for comprehensive 3D geometric prediction. It integrates diverse geometric priors (camera poses, calibrated intrinsics, depth maps) and simultaneously generates various 3D representations (point clouds, multi-view depths, camera parameters, surface normals, 3D Gaussians) in a single forward pass.

☯️ HunyuanWorld-Mirror Introduction

Architecture

HunyuanWorld-Mirror consists of two key components:

(1) Multi-Modal Prior Prompting: A mechanism that embeds diverse prior modalities, including calibrated intrinsics, camera pose, and depth, into the feed-forward model. Given any subset of the available priors, we utilize several lightweight encoding layers to convert each modality into structured tokens.

(2) Universal Geometric Prediction: A unified architecture capable of handling the full spectrum of 3D reconstruction tasks from camera and depth estimation to point map regression, surface normal estimation, and novel view synthesis.
