10
11 --- Purpose: Provides functions for basic geometric computations on
12 -- elementary curves such as conics and lines in 2D and 3D space.
13 -- This includes:
14 -- - calculation of a point or derived vector on a 2D or
15 -- 3D curve where:
16 -- - the curve is provided by the gp package, or
17 -- defined in reference form (as in the gp package),
18 -- and
19 -- - the point is defined by a parameter,
20 -- - evaluation of the parameter corresponding to a point
21 -- on a 2D or 3D curve from gp,
22 -- - various elementary computations which allow you to
23 -- position parameterized values within the period of a curve.
24 -- Notes:
25 -- - ElCLib stands for Elementary Curves Library.
26 -- - If the curves provided by the gp package are not
27 -- explicitly parameterized, they still have an implicit
28 -- parameterization, analogous to that which they infer
29 -- for the equivalent Geom or Geom2d curves.

35 InPeriod(U, UFirst, ULast : Real) returns Real;
36
37 ---Purpose: Return a value in the range <UFirst, ULast> by
38 -- adding or removing the period <ULast - UFirst> to
39 -- <U>.

41 AdjustPeriodic(UFirst, ULast, Precision : Real;
42 U1, U2 : in out Real);
43
44 ---Purpose: Adjust U1 and U2 in the parametric range UFirst
45 -- Ulast of a periodic curve, where ULast -
46 -- UFirst is its period. To do this, this function:
47 -- - sets U1 in the range [ UFirst, ULast ] by
48 -- adding/removing the period to/from the value U1, then
49 -- - sets U2 in the range [ U1, U1 + period ] by
50 -- adding/removing the period to/from the value U2.
51 -- Precision is used to test the equalities.

588 -- system (i.e. 2D space) are lined up respectively with the
589 -- "X Axis" and "Y Axis" of the 3D coordinate system, Pos.
