Detailed Description

superclass for homogeneous transformations

vtkHomogeneousTransform provides a generic interface for homogeneous transformations, i.e. transformations which can be represented by multiplying a 4x4 matrix with a homogeneous coordinate.

const

void vtkHomogeneousTransform::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

void vtkHomogeneousTransform::TransformPoints ( vtkPoints *  inPts, vtkPoints *  outPts  )

virtual

Apply the transformation to a series of points, and append the results to outPts.

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkLinearTransform, and vtkIdentityTransform.

virtual void vtkHomogeneousTransform::TransformPointsNormalsVectors ( vtkPoints *  inPts, vtkPoints *  outPts, vtkDataArray *  inNms, vtkDataArray *  outNms, vtkDataArray *  inVrs, vtkDataArray *  outVrs  )

virtual

Apply the transformation to a combination of points, normals and vectors.

Reimplemented from vtkAbstractTransform.

Reimplemented in vtkLinearTransform, and vtkIdentityTransform.

void vtkHomogeneousTransform::GetMatrix

(

vtkMatrix4x4 *

m

)

Get a copy of the internal transformation matrix. The transform is Updated first, to guarantee that the matrix is valid.

vtkMatrix4x4* vtkHomogeneousTransform::GetMatrix ( )

inline

Get a pointer to an internal vtkMatrix4x4 that represents the transformation. An Update() is called on the transform to ensure that the matrix is up-to-date when you get it. You should not store the matrix pointer anywhere because it might become stale.

Definition at line 63 of file vtkHomogeneousTransform.h.

vtkHomogeneousTransform* vtkHomogeneousTransform::GetHomogeneousInverse ( )

inline

Just like GetInverse(), but includes typecast to vtkHomogeneousTransform.

Definition at line 68 of file vtkHomogeneousTransform.h.

void vtkHomogeneousTransform::InternalTransformPoint ( const float  in[3], float  out[3]  )

virtual

This will calculate the transformation without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.
