vtkImplicitVolume treats a volume (e.g., structured point dataset) as if it were an implicit function. This means it computes a function value and gradient. vtkImplicitVolume is a concrete implementation of vtkImplicitFunction.
vtkImplicitDataSet computes the function (at the point x) by performing cell interpolation. That is, it finds the cell containing x, and then uses the cell's interpolation functions to compute an interpolated scalar value at x. (A similar approach is used to find the gradient, if requested.) Points outside of the dataset are assigned the value of the ivar OutValue, and the gradient value OutGradient.
|
Evaluate the ImplicitVolume. This returns the interpolated scalar value at x[3]. Implements vtkImplicitFunction. |
|
Evaluate ImplicitVolume gradient. Implements vtkImplicitFunction. |
|
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. |
|
Returns the mtime also considering the volume. Reimplemented from vtkImplicitFunction. |
|
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. |
|
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. |
|
Construct an vtkImplicitVolume with no initial volume; the OutValue set to a large negative number; and the OutGradient set to (0,0,1). Reimplemented from vtkObject. |
|
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. |
|
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. |
|
Set the function gradient to use for points outside of the dataset. |
|
Set the function value to use for points outside of the dataset. |
|
Specify the volume for the implicit function. |
