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

virtual const char* vtkImplicitBoolean::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImplicitFunction.

int vtkImplicitBoolean::IsTypeOf const char *    type [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 *    type [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.

vtkImplicitBoolean* vtkImplicitBoolean::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

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.

vtkImplicitBoolean* vtkImplicitBoolean::New   [static]
 

Default boolean method is union.

Reimplemented from vtkObject.

float vtkImplicitBoolean::EvaluateFunction float    x[3] [virtual]
 

Evaluate boolean combinations of implicit function using current operator.

Reimplemented from vtkImplicitFunction.

float vtkImplicitBoolean::EvaluateFunction float    x,
float    y,
float    z
[inline]
 

Evaluate boolean combinations of implicit function using current operator.

Reimplemented from vtkImplicitFunction.

Definition at line 92 of file vtkImplicitBoolean.h.

void vtkImplicitBoolean::EvaluateGradient float    x[3],
float    g[3]
[virtual]
 

Evaluate gradient of boolean combination.

Reimplemented from 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.

Definition at line 109 of file vtkImplicitBoolean.h.

virtual void vtkImplicitBoolean::SetOperationType int    [virtual]
 

Specify the type of boolean operation.

virtual int vtkImplicitBoolean::GetOperationType   [virtual]
 

Specify the type of boolean operation.

void vtkImplicitBoolean::SetOperationTypeToUnion   [inline]
 

Specify the type of boolean operation.

Definition at line 115 of file vtkImplicitBoolean.h.

void vtkImplicitBoolean::SetOperationTypeToIntersection   [inline]
 

Specify the type of boolean operation.

Definition at line 117 of file vtkImplicitBoolean.h.

void vtkImplicitBoolean::SetOperationTypeToDifference   [inline]
 

Specify the type of boolean operation.

Definition at line 119 of file vtkImplicitBoolean.h.

void vtkImplicitBoolean::SetOperationTypeToUnionOfMagnitudes   [inline]
 

Specify the type of boolean operation.

Definition at line 121 of file vtkImplicitBoolean.h.

const char * vtkImplicitBoolean::GetOperationTypeAsString void    [inline]
 

Return the boolean operation type as a descriptive character string.

Definition at line 140 of file vtkImplicitBoolean.h.
