LandmarkTransform

Source (.js)Source (.d.ts)

Introduction

vtkLandmarkTransform is a cell which representant a triangle. It contains static method to make some computations directly link to triangle.

Usage

'''js import vtkLandmarkTransform from '@kitware/vtk.js/Common/Transform/LandmarkTransform';

const transform = LandmarkTransform.New(); transform.setMode(Mode.RIGID_BODY); transform.setSourceLandmark(...); // vtkPoints transform.setTargetLandmark(...); // vtkPoints transform.update(); const transformMatrix = transform.getMatrix(); '''

Methods

extend

Method used to decorate a given object (publicAPI+model) with vtkLandmarkTransform characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	ILandmarkTransformInitialValues	No	(default: {})

getMatrix

Mat4 matrix, result of the landmark transform. If vtkLandmarkTransformed failed, default is identity.

getMode

Get the number of degrees of freedom to constrain the solution to.

getSourceLandmark

Get list of 3D points which defines the source points.

getTargetLandmark

Get list of 3D points which defines the target points.

newInstance

Method used to create a new instance of vtkLandmarkTransform.

Argument	Type	Required	Description
initialValues	ILandmarkTransformInitialValues	No	for pre-setting some of its content

setMode

Set the number of degrees of freedom to constrain the solution to:

• Mode.RIGID_BODY : Rotation and translation onlu
• Mode.SIMILARITY : rotation, translation and isotropic scaling
• Mode.AFFINE : collinearity is preserved. Ratios of distances along a line are preserved.

Argument	Type	Required	Description
mode	Mode	Yes	The value of mode.

setSourceLandmark

Set list of 3D points which defines the source points.

Argument	Type	Required	Description
sourceLandmark	vtkPoints	Yes

setTargetLandmark

Set list of 3D points which defines the target points.

Argument	Type	Required	Description
targetLandmark	vtkPoints	Yes

update

Launch the computation of the matrix according to target and source points.
