GeometricObjects Interface CATPNurbs
Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATPNurbs
Interface representing a Nurbs curve in a surface space.
The CATPNurbs is created by the CreatePNurbs
method of the CATGeoFactory interface and deleted with the Remove method.
It is defined with:
| CATKnotVector | KnotVector |
The knot vector for the polynomial basis definition |
| CATMathSetOfPoints | Vertices |
The set of control points |
| CATBoolean | IsRational |
1 if the nurbs is rational, else 0 |
| double[] | Weigths |
The weigths array if IsRational |
| CATSurface | iSupport |
The surface on which the Nurbs is defined |

Methods
o GetNumberOfControlPoints
| public virtual GetNumberOfControlPoints( | ) |
-
Returns the number control points of this CATPNurbs.
- Returns:
- The number of control points.
o GetOneControlPoint
| public virtual GetOneControlPoint( | | iNum, |
| | ioControlPoint) |
-
Retrieves the parameter of a control point of this CATPNurbs.
- Parameters:
-
- iNum
- The control point number starting at 1.
- ioControlPoint
- The parameter corresponding to the iNum-th control point.
o GetOneWeight
| public virtual GetOneWeight( | | iNum) |
-
Returns the weight associated with a control point of this CATPNurbs.
- Parameters:
-
- iNum
- The control point number starting at 1.
- return
- The associated weight.
o GetOriginalParametrisationDATA
| public virtual GetOriginalParametrisationDATA( | | ioCoefficient, |
| | ioShift) |
-
Gets the original parameterization.
If created with the CatAutomaticParameterization default mode by the factory, the Nurbs
is internally re-parameterized. This allows you to recover the coefficient and the shift that
correspond to your own parameterization.
- Parameters:
-
- ioCoefficient
- The multiplicative coefficent.
- ioShift
- The shift.
o IsRational
| public virtual IsRational( | ) |
-
Tests if this CATPNurbs is rational.
- Returns:
- The result of the test.
Legal values:
- FALSE
- if it is not rational.
- TRUE
- if it is rational.
o Set
| public virtual Set( | | iNewKnotVector, |
| const | iNewIsRational, |
| const | iNewVertices, |
| const | iNewWeights, |
| | iNewSupport, |
| const | iParameterizationOption | = CatAutomaticParameterization) |
-
- Deprecated:
- V5R14 SetData
o SetData
| public virtual SetData( | const | iNewKnotVector, |
| const | iNewIsRational, |
| const | iNewVertices, |
| const | iNewWeights, |
| | iNewSupport, |
| const | iParameterizationOption | = CatAutomaticParameterization) |
-
Modifies all the characteristics of this CATPNurbs.
- Parameters:
-
- iNewKnotVector
- The new definition of the polynomial basis.
- iNewIsRational
- Legal values:
- FALSE
- if it is not rational.
- TRUE
- if it is rational.
- iNewVertices
- The set of new control points.
- iNewWeights
- The array of corresponding weights (one weight per control point).
- iNewSupport
- The new surface on which this CATPNurbs will be defined.
- iParameterizationOption
- The option of parameterization. By default, the parameterization of the NURBS is modified to better
fit internal criteria. In this case, you can recover the initial parameterization
with the
method.
o SetOneControlPoint
| public virtual SetOneControlPoint( | | iNum, |
| const | iNewCoord) |
-
Modifies a control point definition of this CATPNurbs.
- Parameters:
-
- iNum
- The control point number starting at 1.
- iNewCoord
- The new parameter of the iNum-th control point.
o SetOneWeight
| public virtual SetOneWeight( | | iNum, |
| | iWeight) |
-
Modifies the weight associated with a control point of this CATPNurbs.
- Parameters:
-
- iNum
- The control point number starting at 1.
