static void | Value (const Standard_Address A, const Standard_Real U, gp_Pnt2d &P) |
| Computes the point
of parameter <u> on the
Curve from HLRBRep <c>.
.
|
static void | D1 (const Standard_Address A, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1) |
| Computes the point
and first derivative <v1>
of parameter <u> on the curve <c>.
.
|
static void | D2 (const Standard_Address A, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2) |
| Computes the point
, the first derivative <v1>
and second derivative <v2> of parameter <u> on the
curve <c>.
.
|
static void | D3 (const Standard_Address A, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2, gp_Vec2d &V3) |
| Computes the point
, the first derivative <v1>,
the second derivative <v2> and third derivative
<v3> of parameter <u> on the curve <c>.
.
|
static Standard_Integer | Continuity (const Standard_Address A) |
| returns the order of continuity of the curve <c>.
returns 1 : first derivative only is computable
returns 2 : first and second derivative only are
computable. returns 3 : first, second and third
are computable.
|
static Standard_Real | FirstParameter (const Standard_Address A) |
| returns the first parameter bound of the curve.
|
static Standard_Real | LastParameter (const Standard_Address A) |
| returns the last parameter bound of the curve.
FirstParameter must be less than LastParamenter.
