◆ AdjustPeriodic()

static void ElCLib::AdjustPeriodic ( const Standard_Real  UFirst,
const Standard_Real  ULast,
const Standard_Real  Precision,
Standard_Real U1,
Standard_Real U2 
)
static

Adjust U1 and U2 in the parametric range UFirst Ulast of a periodic curve, where ULast - UFirst is its period. To do this, this function:

  • sets U1 in the range [ UFirst, ULast ] by adding/removing the period to/from the value U1, then
  • sets U2 in the range [ U1, U1 + period ] by adding/removing the period to/from the value U2. Precision is used to test the equalities.
