Detailed Description

the geotrans_interpolation_context structure is passed as the argument of geometric transformation interpolation functions.

This structure can be partially filled (for example the xreal will be computed if needed as long as pgp+ii is known). See also fem_interpolation_context in getfem_fem.h. The name of member data, and the computations done by this structure are heavily described in the GetFEM Kernel Documentation.
