Surface deviation
Two directions. Measured boundary points. Your files stay on this computer.

Decimal point: 0.1 mm. Rounded display uses 3 significant digits; this is not an accuracy estimate. Full numerical values remain in the saved record.
✕ Magenta crosses: strictly above the color limit.
Drag or use arrow keys to rotate. Colors belong to measured points; gaps are unmeasured. Larger points are nearer the viewer. Gray lines join samples along individual edges as approximate shape guides; they are not measured surface coverage. Both directions use the same color scale.
Sample observations, not certified Hausdorff distance. An observed zero does not establish identical shapes. No automatic alignment or conformity decision.
