Detailed Description

describes a 4x4 matrix transformation

A vtkPerspectiveTransform can be used to describe the full range of homogeneous transformations. It was designed in particular to describe a camera-view of a scene.

The order in which you set up the display coordinates (via AdjustZBuffer() and AdjustViewport()), the projection (via Perspective(), Frustum(), or Ortho()) and the camera view (via SetupCamera()) are important. If the transform is in PreMultiply mode, which is the default, set the Viewport and ZBuffer first, then the projection, and finally the camera view. Once the view is set up, the Translate and Rotate methods can be used to move the camera around in world coordinates. If the Oblique() or Stereo() methods are used, they should be called just before SetupCamera().

In PostMultiply mode, you must perform all transformations in the opposite order. This is necessary, for example, if you already have a perspective transformation set up but must adjust the viewport. Another example is if you have a view transformation, and wish to perform translations and rotations in the camera's coordinate system rather than in world coordinates.

The SetInput and Concatenate methods can be used to create a transformation pipeline with vtkPerspectiveTransform. See vtkTransform for more information on the transformation pipeline.

	)

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 vtkHomogeneousTransform.

void vtkPerspectiveTransform::Identity ( )

inline

Set this transformation to the identity transformation. If the transform has an Input, then the transformation will be reset so that it is the same as the Input.

Definition at line 65 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::Inverse ( )

inlinevirtual

Invert the transformation. This will also set a flag so that the transformation will use the inverse of its Input, if an Input has been set.

Implements vtkAbstractTransform.

Definition at line 70 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::AdjustViewport	(	double	oldXMin,
		double	oldXMax,
		double	oldYMin,
		double	oldYMax,
		double	newXMin,
		double	newXMax,
		double	newYMin,
		double	newYMax
	)

Perform an adjustment to the viewport coordinates. By default Ortho, Frustum, and Perspective provide a window of ([-1,+1],[-1,+1]). In PreMultiply mode, you call this method before calling Ortho, Frustum, or Perspective. In PostMultiply mode you can call it after. Note that if you must apply both AdjustZBuffer and AdjustViewport, it makes no difference which order you apply them in.

void vtkPerspectiveTransform::AdjustZBuffer	(	double	oldNearZ,
		double	oldFarZ,
		double	newNearZ,
		double	newFarZ
	)

Perform an adjustment to the Z-Buffer range that the near and far clipping planes map to. By default Ortho, Frustum, and Perspective map the near clipping plane to -1 and the far clipping plane to +1. In PreMultiply mode, you call this method before calling Ortho, Frustum, or Perspective. In PostMultiply mode you can call it after.

void vtkPerspectiveTransform::Ortho	(	double	xmin,
		double	xmax,
		double	ymin,
		double	ymax,
		double	znear,
		double	zfar
	)

Create an orthogonal projection matrix and concatenate it by the current transformation. The matrix maps [xmin,xmax], [ymin,ymax], [-znear,-zfar] to [-1,+1], [-1,+1], [+1,-1].

void vtkPerspectiveTransform::Frustum	(	double	xmin,
		double	xmax,
		double	ymin,
		double	ymax,
		double	znear,
		double	zfar
	)

Create an perspective projection matrix and concatenate it by the current transformation. The matrix maps a frustum with a back plane at -zfar and a front plane at -znear with extent [xmin,xmax],[ymin,ymax] to [-1,+1], [-1,+1], [+1,-1].

void vtkPerspectiveTransform::Perspective	(	double	angle,
		double	aspect,
		double	znear,
		double	zfar
	)

Create a perspective projection matrix by specifying the view angle (this angle is in the y direction), the aspect ratio, and the near and far clipping range. The projection matrix is concatenated with the current transformation. This method works via Frustum.

void vtkPerspectiveTransform::Shear	(	double	dxdz,
		double	dydz,
		double	zplane
	)

Create a shear transformation about a plane at distance z from the camera. The values dxdz (i.e. dx/dz) and dydz specify the amount of shear in the x and y directions. The 'zplane' specifies the distance from the camera to the plane at which the shear causes zero displacement. Generally you want this plane to be the focal plane. This transformation can be used in combination with Ortho to create an oblique projection. It can also be used in combination with Perspective to provide correct stereo views when the eye is at arbitrary but known positions relative to the center of a flat viewing screen.

void vtkPerspectiveTransform::Stereo	(	double	angle,
		double	focaldistance
	)

Create a stereo shear matrix and concatenate it with the current transformation. This can be applied in conjunction with either a perspective transformation (via Frustum or Projection) or an orthographic projection. You must specify the distance from the camera plane to the focal plane, and the angle between the distance vector and the eye. The angle should be negative for the left eye, and positive for the right. This method works via Oblique.

void vtkPerspectiveTransform::SetupCamera	(	const double	position[3],
		const double	focalpoint[3],
		const double	viewup[3]
	)

Set a view transformation matrix for the camera (this matrix does not contain any perspective) and concatenate it with the current transformation.

void vtkPerspectiveTransform::SetupCamera	(	double	p0,
		double	p1,
		double	p2,
		double	fp0,
		double	fp1,
		double	fp2,
		double	vup0,
		double	vup1,
		double	vup2

		double	z
	)

void vtkPerspectiveTransform::RotateWXYZ	(	double	angle,
		const double	axis[3]
	)

void vtkPerspectiveTransform::Scale	(	double	x,
		double	y,
		double	z
	)

Definition at line 189 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::SetMatrix ( vtkMatrix4x4 * matrix )

inline

Set the current matrix directly. This actually calls Identity(), followed by Concatenate(matrix).

Definition at line 195 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::SetMatrix ( const double elements[16] )

inline

Set the current matrix directly. This actually calls Identity(), followed by Concatenate(matrix).

Definition at line 197 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::Concatenate ( vtkMatrix4x4 * matrix )

inline

Concatenates the matrix with the current transformation according to PreMultiply or PostMultiply semantics.

Definition at line 204 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::Concatenate ( const double elements[16] )

inline

Concatenates the matrix with the current transformation according to PreMultiply or PostMultiply semantics.

Definition at line 206 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::Concatenate ( vtkHomogeneousTransform * transform )

Concatenate the specified transform with the current transformation according to PreMultiply or PostMultiply semantics. The concatenation is pipelined, meaning that if any of the transformations are changed, even after Concatenate() is called, those changes will be reflected when you call TransformPoint().

void vtkPerspectiveTransform::PreMultiply ( )

inline

Sets the internal state of the transform to PreMultiply. All subsequent operations will occur before those already represented in the current transformation. In homogeneous matrix notation, M = M*A where M is the current transformation matrix and A is the applied matrix. The default is PreMultiply.

Definition at line 223 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::PostMultiply ( )

inline

Definition at line 242 of file vtkPerspectiveTransform.h.

vtkHomogeneousTransform* vtkPerspectiveTransform::GetConcatenatedTransform ( int i )

Get one of the concatenated transformations as a vtkAbstractTransform. These transformations are applied, in series, every time the transformation of a coordinate occurs. This method is provided to make it possible to decompose a transformation into its constituents, for example to save a transformation to a file.

Definition at line 253 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::SetInput ( vtkHomogeneousTransform * input )

Set the input for this transformation. This will be used as the base transformation if it is set. This method allows you to build a transform pipeline: if the input is modified, then this transformation will automatically update accordingly. Note that the InverseFlag, controlled via Inverse(), determines whether this transformation will use the Input or the inverse of the Input.

vtkHomogeneousTransform* vtkPerspectiveTransform::GetInput ( )

inline

Set the input for this transformation. This will be used as the base transformation if it is set. This method allows you to build a transform pipeline: if the input is modified, then this transformation will automatically update accordingly. Note that the InverseFlag, controlled via Inverse(), determines whether this transformation will use the Input or the inverse of the Input.

Definition at line 288 of file vtkPerspectiveTransform.h.

int vtkPerspectiveTransform::GetInverseFlag ( )

inline

Get the inverse flag of the transformation. This controls whether it is the Input or the inverse of the Input that is used as the base transformation. The InverseFlag is flipped every time Inverse() is called. The InverseFlag is off when a transform is first created.

Definition at line 296 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::Push ( )

inline

Pushes the current transformation onto the transformation stack.

Definition at line 302 of file vtkPerspectiveTransform.h.

void vtkPerspectiveTransform::Pop ( )

inline

vtkAbstractTransform* vtkPerspectiveTransform::MakeTransform ( )

virtual

Make a new transform of the same type – you are responsible for deleting the transform when you are done with it.

Implements vtkAbstractTransform.

int vtkPerspectiveTransform::CircuitCheck ( vtkAbstractTransform * transform )

virtual

Check for self-reference. Will return true if concatenating with the specified transform, setting it to be our inverse, or setting it to be our input will create a circular reference. CircuitCheck is automatically called by SetInput(), SetInverse(), and Concatenate(vtkXTransform *). Avoid using this function, it is experimental.
