## Member Function Documentation

vtkCardinalSpline* vtkCardinalSpline::New | ( |  | ) | `[static]`

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkCardinalSpline::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkSpline.

int vtkCardinalSpline::IsTypeOf | ( | const char * | type | ) | `[static]`

| Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkSpline.

virtual int vtkCardinalSpline::IsA | ( | const char * | type | ) | `[virtual]`

| Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkSpline.

vtkCardinalSpline* vtkCardinalSpline::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkSpline.

void vtkCardinalSpline::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

| Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSpline.

void vtkCardinalSpline::Compute | ( |  | ) | `[virtual]`

| Compute Cardinal Splines for each dependent variable Implements vtkSpline.

virtual float vtkCardinalSpline::Evaluate | ( | float | t | ) | `[virtual]`

| Evaluate a 1D cardinal spline. Implements vtkSpline.

virtual void vtkCardinalSpline::DeepCopy | ( | vtkSpline * | s | ) | `[virtual]`

| Deep copy of cardinal spline data. Reimplemented from vtkSpline.

void vtkCardinalSpline::Fit1D | ( | int | n,
|  | float * | x,
|  | float * | y,
|  | float * | w,
|  | float | coefficients[][4],
|  | int | leftConstraint,
|  | float | leftValue,
|  | int | rightConstraint,
|  | float | rightValue
| ) | `[protected]`

void vtkCardinalSpline::FitClosed1D | ( | int | n,
|  | float * | x,
|  | float * | y,
|  | float * | w,
|  | float | coefficients[][4]
| ) | `[protected]`
