void InternalTransformPoint(const float in[3], float out[3]) override
This will calculate the transformation without calling Update.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void TransformPointsNormalsVectors(vtkPoints *inPts, vtkPoints *outPts, vtkDataArray *inNms, vtkDataArray *outNms, vtkDataArray *inVrs, vtkDataArray *outVrs, int nOptionalVectors=0, vtkDataArray **inVrsArr=nullptr, vtkDataArray **outVrsArr=nullptr) override
Apply the transformation to a combination of points, normals and vectors.
virtual void TransformNormals(vtkDataArray *inNms, vtkDataArray *outNms)
Apply the transformation to a series of normals, and append the results to outNms.
virtual vtkAbstractTransform * MakeTransform()=0
Make another transform of the same type.
virtual void InternalTransformVector(const float in[3], float out[3])
This will calculate the transformation without calling Update.
void TransformPoints(vtkPoints *inPts, vtkPoints *outPts) override
Apply the transformation to a series of points, and append the results to outPts.
virtual void InternalTransformNormal(const float in[3], float out[3])
This will calculate the transformation without calling Update.
virtual void TransformVectors(vtkDataArray *inVrs, vtkDataArray *outVrs)
Apply the transformation to a series of vectors, and append the results to outVrs.

a transform that doesn't do anything
void InternalTransformDerivative(const float in[3], float out[3], float derivative[3][3]) override
This will calculate the transformation as well as its derivative without calling Update.
void InternalDeepCopy(vtkAbstractTransform *transform) override
Perform any subclass-specific DeepCopy.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
void Inverse() override
Invert the transformation.
