1 Source - 1 Target Point Cloud Comparison

Drag on the GT point cloud below to rotate the view — every other point cloud follows it in sync.

VGGT-DD
VGGT-Z3D
WM-DD
WM-Z3D

From the visualizations above, we observe that point clouds obtained by projecting the depth-diffusion baselines' predicted depth maps (WM-DD and VGGT-DD) are considerably noisier, with scattered, uneven surfaces. Their Z3D counterparts, by contrast, produce smooth, coherent point clouds.

Drag to rotate — all point clouds stay in sync. Pick an example above to switch scenes.

Drag on the GT point cloud below to rotate the view — the other two follow it in sync.

WM-Z3D

From the visualizations above, we observe that point clouds obtained by projecting Z3D's predicted depth maps are smooth and coherent.

Drag to rotate — all three point clouds stay in sync. Pick an example above to switch scenes.

Depth Gradient Comparison - World Mirror

WM-Z3D wm-z3d zoomed depth gradient

Pick an example above to switch scenes.

From the visualizations above, we observe that depth maps predicted by the depth-diffusion baseline (WM-DD) contain patchy artifacts. The corresponding depth gradients further reveal that WM-DD produces noisy, inconsistent gradients, whereas WM-Z3D yields smoother, more coherent depth structure. The last column shows the zoomed in view of the highlighted section in the depth gradient images.
