  • Fig. 2 Completed virtual unwrapping for the En-Gedi scroll.
  • Fig. 3 Segmentation challenges in the En-Gedi scroll, based on examples in the slice view.

    Double/split layering and challenging cell structure (left), ambiguous layers with unknown material (middle left), high-density “bubbling” on the secondary layer (middle right), and gap in the primary layer (right).

  • Fig. 4 A portion of the segmented surface and how it intersects the volume.
  • Fig. 5 The importance of accurate surface localization on the final generated texture.

    (A) Texture generated when the surface is only partially localized. (B) Texture generated when surface is accurately localized.

  • Fig. 6 The geometric parameters for directional texturing.
  • Fig. 7 The effect of directional texturing to improve ink response.

    (Left) Intersection of the mesh with the volume. (Right) Directional texturing with a neighborhood radius of 7 voxels.

  • Fig. 8 Demonstration of stored provenance chain.

    The generated geometric transformations can map a region and point of interest in the master view (left) back to their 3D positions within the volume (right).

  • Fig. 9 Partial transcription and translation of recovered text.

    (Column 1) Lines 5 to 7 from the En-Gedi scroll.

  • Fig. 10 Timeline placing the En-Gedi scroll within the context of other biblical discoveries.
