Details

'SFC_RULES_3x3_PEANO', 'SFC_RULES_3x3_MEANDER' and 'SFC_RULES_3x3_COMBINED', 'SFC_RULES_MEANDER_4x4_1', 'SFC_RULES_MEANDER_4x4_2' also contain the "flipped" expansion rules.

'SFC_RULES_3x3_COMBINED' is a combination of 'SFC_RULES_3x3_PEANO' and 'SFC_RULES_3x3_MEANDER' where in 'SFC_RULES_3x3_PEANO', 'J' is replaced by its original pattern 'I'.

'SFC_RULES_4x4_MEANDER_1' and 'SFC_RULES_4x4_MEANDER_2' are extension rules of Meander curves (3x3) on the 4x4 mode It is only for the demonstration purpose, thus only 'I/R/L' are supported.

Value

'sfc_rules' objects.
