represent and manipulate 4x4 transformation matrices
Definition: vtkMatrix4x4.h:41
superclass for homogeneous transformations
virtual void TransformPoints(vtkPoints *inPts, vtkPoints *outPts)
Apply the transformation to a series of points, and append the results to outPts. ...
vtkAbstractTransform * GetInverse()
Get the inverse of this transform.
vtkHomogeneousTransform * GetHomogeneousInverse()
Just like GetInverse(), but includes typecast to vtkHomogeneousTransform.
virtual void TransformPointsNormalsVectors(vtkPoints *inPts, vtkPoints *outPts, vtkDataArray *inNms, vtkDataArray *outNms, vtkDataArray *inVrs, vtkDataArray *outVrs)
Apply the transformation to a combination of points, normals and vectors.
void Update()
Update the transform to account for any changes which have been made.
a simple class to control print indentation
Definition: vtkIndent.h:39
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
abstract superclass for arrays of numeric data
Definition: vtkDataArray.h:54
superclass for all geometric transformations
virtual void InternalTransformPoint(const float in[3], float out[3])=0
This will calculate the transformation without calling Update.
virtual void InternalTransformDerivative(const float in[3], float out[3], float derivative[3][3])=0
This will transform a point and, at the same time, calculate a 3x3 Jacobian matrix that provides the ...
vtkMatrix4x4 * GetMatrix()
Get a pointer to an internal vtkMatrix4x4 that represents the transformation.
represent and manipulate 3D points
