Detailed Description

spherical to rectangular coords and back

vtkSphericalTransform will convert (r,phi,theta) coordinates to (x,y,z) coordinates and back again. The angles are given in radians. By default, it converts cylindrical coordinates to rectangular, but GetInverse() returns a transform that will do the opposite. The equation that is used is x = r*sin(phi)*cos(theta), y = r*sin(phi)*sin(theta), z = r*cos(phi).

Warning:

This transform is not well behaved along the line x=y=0 (i.e. along the z-axis)

Member Function Documentation

static vtkSphericalTransform* vtkSphericalTransform::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkSphericalTransform::GetClassName

(

)

[virtual]

Reimplemented from vtkWarpTransform.

static int vtkSphericalTransform::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkWarpTransform.

virtual int vtkSphericalTransform::IsA

(

const char *

name

)

[virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkWarpTransform.

static vtkSphericalTransform* vtkSphericalTransform::SafeDownCast

(

vtkObject *

o

)

[static]

Reimplemented from vtkWarpTransform.

virtual void vtkSphericalTransform::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			[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 vtkWarpTransform.

vtkAbstractTransform* vtkSphericalTransform::MakeTransform

(

)

[virtual]

Make another transform of the same type.

Implements vtkAbstractTransform.

void vtkSphericalTransform::InternalDeepCopy

(

vtkAbstractTransform *

transform

)

[protected, virtual]

Copy this transform from another of the same type.

Reimplemented from vtkAbstractTransform.

void vtkSphericalTransform::ForwardTransformPoint	(	const float	in[3],
		float	out[3]
	)			[protected, virtual]

Internal functions for calculating the transformation.

Implements vtkWarpTransform.

void vtkSphericalTransform::ForwardTransformPoint	(	const double	in[3],
		double	out[3]
	)			[protected, virtual]

Internal functions for calculating the transformation.

Implements vtkWarpTransform.

void vtkSphericalTransform::ForwardTransformDerivative	(	const float	in[3],
		float	out[3],
		float	derivative[3][3]
	)			[protected, virtual]

Calculate the forward transform as well as the derivative.

Implements vtkWarpTransform.

void vtkSphericalTransform::ForwardTransformDerivative	(	const double	in[3],
		double	out[3],
		double	derivative[3][3]
	)			[protected, virtual]

Calculate the forward transform as well as the derivative.

Implements vtkWarpTransform.

void vtkSphericalTransform::InverseTransformPoint	(	const float	in[3],
		float	out[3]
	)			[protected, virtual]

If the InverseFlag is set to 1, then a call to InternalTransformPoint results in a call to InverseTransformPoint. The inverse transformation is calculated from using Newton's method.

Reimplemented from vtkWarpTransform.

void vtkSphericalTransform::InverseTransformPoint	(	const double	in[3],
		double	out[3]
	)			[protected, virtual]

If the InverseFlag is set to 1, then a call to InternalTransformPoint results in a call to InverseTransformPoint. The inverse transformation is calculated from using Newton's method.

Reimplemented from vtkWarpTransform.

void vtkSphericalTransform::InverseTransformDerivative	(	const float	in[3],
		float	out[3],
		float	derivative[3][3]
	)			[protected, virtual]

Calculate the inverse transform as well as the derivative of the forward transform (that's correct: the derivative of the forward transform, not of the inverse transform)

Reimplemented from vtkWarpTransform.

void vtkSphericalTransform::InverseTransformDerivative	(	const double	in[3],
		double	out[3],
		double	derivative[3][3]
	)			[protected, virtual]

Calculate the inverse transform as well as the derivative of the forward transform (that's correct: the derivative of the forward transform, not of the inverse transform)
