3d structural restoration of a geological setting

A non-transitory data storage medium having recorded thereon a computer program comprising instructions for performing a method comprising:

• performing a 3D structural restoration of a geological setting with a computer system, including unfolding one or more geological surfaces of the geological setting, the unfolding comprising for each respective geological surface:
• providing a 3D triangulated surface representing the respective geological surface;
• and
• determining a conformal flattening that transforms the 3D triangulated surface into a 2D triangulated surface, the conformal flattening being an iso-topographic mapping which substantially preserves angles.

A system comprising a processor coupled to a memory, the memory having recorded thereon a computer program including instructions, the system being configured to perform a method comprising:

• performing a 3D structural restoration of a geological setting with a computer system, including unfolding one or more geological surfaces of the geological setting, the unfolding comprising for each respective geological surface:
• providing a 3D triangulated surface representing the respective geological surface;
• and
• determining a conformal flattening that transforms the 3D triangulated surface into a 2D triangulated surface, the conformal flattening being an iso-topographic mapping which substantially preserves angles.
