Freeform Origami

This software is a design software that allows users to interact with origami forms while altering the crease pattern of the model. The software can keep:

• Developability (foldable from a piece of paper)
• Flat-foldability (foldable into a flat shape)
• Planarity of facets (paper do not twist in 3D form)
• Point coordinate coincidence
• Paper size

• Binary for win X64FreeformOrigamiX64_1_1.zip (ver 1.1)
• Binary for win32FreeformOrigami030.zip (ver 0.3)

Known Issues

[Solved] Crashing on Intel Graphics (from 2018)

• Way-around 1: Revert Intel Graphics Driver to an older version
  • Crash reported:
    Intel HD Graphics 520 (24.20.100.6290 2018/08/27)
  • Noncrash reported:
    Intel HD Graphics 520 (21.20.16.4542 2016/10/24)
    Intel HD Graphics 620 (21.20.16.4821 2017/10/02)
• Way-around 2: Use other GPU (if the machine has one) for this application.
