Filling 3D pockets

So what needs to be done

• Input
• Image
• Height map
• Set of cuts
• Output
• 3D model with 3D gaps Filled.

9
How (1)

• Building the ripped mesh in 3D
• Mapping the image as texture to the mesh shown
  parts
• Extending the mesh to include additional facets
  on the hidden parts.
• Completing the image at the missing parts, and
  texture map the mesh extensions.
• Boundary alpha matting

10
What needs to be done (bonus)

• Shape completion
• Simple viewer
• VRML/AVI export

LDI - Layered Depth Images
Shade, Gortler , Hey , Szeliskiz Siggraph 1998
12
What LDI approach

• Input
• A set of pixels and their depth
• A set of cuts
• LDI map with expended patches.
