Detailed Description

implicit function consisting of boolean combinations of implicit functions

vtkImplicitBoolean is an implicit function consisting of boolean combinations of implicit functions. The class has a list of functions (FunctionList) that are combined according to a specified operator (VTK_UNION or VTK_INTERSECTION or VTK_DIFFERENCE). You can use nested combinations of vtkImplicitFunction's (and/or vtkImplicitBoolean) to create elaborate implicit functions. vtkImplicitBoolean is a concrete implementation of vtkImplicitFunction.

The operators work as follows. The VTK_UNION operator takes the minimum value of all implicit functions. The VTK_INTERSECTION operator takes the maximum value of all implicit functions. The VTK_DIFFERENCE operator subtracts the 2nd through last implicit functions from the first. The VTK_UNION_OF_MAGNITUDES takes the minimum absolute value of the implicit functions.

Member Function Documentation

static int vtkImplicitBoolean::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

virtual int vtkImplicitBoolean::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

static vtkImplicitBoolean* vtkImplicitBoolean::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkImplicitFunction.

virtual vtkObjectBase* vtkImplicitBoolean::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkImplicitFunction.

vtkImplicitBoolean* vtkImplicitBoolean::NewInstance ( ) const

Reimplemented from vtkImplicitFunction.

void vtkImplicitBoolean::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 vtkImplicitFunction.

static vtkImplicitBoolean* vtkImplicitBoolean::New ( ) [static]

Default boolean method is union.

Reimplemented from vtkObject.

double vtkImplicitBoolean::EvaluateFunction ( double x[3] ) [virtual]

Evaluate boolean combinations of implicit function using current operator.

Implements vtkImplicitFunction.

double vtkImplicitBoolean::EvaluateFunction	(	double	x,
		double	y,
		double	z
	)		`[inline]`

Evaluate boolean combinations of implicit function using current operator.

Reimplemented from vtkImplicitFunction.

Definition at line 69 of file vtkImplicitBoolean.h.

void vtkImplicitBoolean::EvaluateGradient	(	double	x[3],
		double	g[3]
	)		`[virtual]`

Evaluate gradient of boolean combination.

Implements vtkImplicitFunction.

unsigned long vtkImplicitBoolean::GetMTime ( ) [virtual]

Override modified time retrieval because of object dependencies.

Reimplemented from vtkImplicitFunction.

void vtkImplicitBoolean::AddFunction ( vtkImplicitFunction * in )

Add another implicit function to the list of functions.

void vtkImplicitBoolean::RemoveFunction ( vtkImplicitFunction * in )

Remove a function from the list of implicit functions to boolean.

vtkImplicitFunctionCollection* vtkImplicitBoolean::GetFunction ( ) [inline]

Return the collection of implicit functions.
