World Tracing

Converts a single image into layered camera-space 3D geometry (six depth layers per pixel) via a world-tracing diffusion transformer treating layers as denoising tokens, using pixel-space flow matching with a mixed noise schedule. Maintains 2D-to-3D correspondence and beats both depth estimators and image-to-3D generators — enabling training-free textured meshes, 3D scene editing and geometry-guided video.
