Usage
vtkHyperOctreeSampleFunction is a source object that
evaluates an implicit function to drive the subdivision
process. The user can specify the threshold over which a
subdivision occurs, the maximum and minimum level of
subdivisions and the dimension of the hyperoctree.
To create an instance of class vtkHyperOctreeSampleFunction,
simply invoke its constructor as follows
obj = vtkHyperOctreeSampleFunction
Methods
The class vtkHyperOctreeSampleFunction has several methods
that can be used. They are listed below. Note that the
documentation is translated automatically from the VTK
sources, and may not be completely intelligible. When in
doubt, consult the VTK website. In the methods listed below,
obj is an instance of the vtkHyperOctreeSampleFunction
class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkHyperOctreeSampleFunction = obj.NewInstance ()
* vtkHyperOctreeSampleFunction = obj.SafeDownCast (vtkObject
o)
* int = obj.GetLevels () - Return the maximum number of
levels of the hyperoctree.
Postcondition:
positive_result: result>=1
* obj.SetLevels (int levels) - Set the maximum number of
levels of the hyperoctree. If GetMinLevels()>=levels,
GetMinLevels() is changed to levels-1.
Precondition:
positive_levels: levels>=1
Postcondition:
is_set: this->GetLevels()==levels
min_is_valid: this->GetMinLevels()<this->GetLevels()
* int = obj.GetMinLevels () - Return the minimal number of
levels of systematic subdivision.
Postcondition:
positive_result: result>=0
* obj.SetMinLevels (int minLevels) - Set the minimal number
of levels of systematic subdivision.
Precondition:
positive_minLevels: minLevels>=0
Postcondition:
is_set: this->GetMinLevels()==minLevels
* double = obj.GetThreshold () - Return the threshold over
which a subdivision is required.
Postcondition:
positive_result: result>0
* obj.SetThreshold (double threshold) - Set the threshold
over which a subdivision is required.
Precondition:
positive_threshold: threshold>=0
Postcondition:
is_set: this->GetThreshold()==threshold
* int = obj.GetDimension () - Return the dimension of the
tree (1D:binary tree(2 children), 2D:quadtree(4 children),
3D:octree (8 children))
Postcondition:
valid_result: result>=1 && result<=3
* obj.SetDimension (int dim)
* obj.SetSize (double , double , double ) - Set the size on
each axis.
* obj.SetSize (double a[3]) - Set the size on each axis.
* double = obj. GetSize () - Return the size on each axis.
* obj.SetOrigin (double , double , double ) - Set the origin
(position of corner (0,0,0) of the root.
* obj.SetOrigin (double a[3]) - Set the origin (position of
corner (0,0,0) of the root.
* double = obj. GetOrigin () - Set the origin (position of
corner (0,0,0) of the root. Return the origin (position of
corner (0,0,0) ) of the root.
* double = obj.GetWidth () - Return the length along the x-
axis.
Postcondition:
positive_result: result>0
* obj.SetWidth (double width) - Set the length along the x-
axis.
Precondition:
positive_width: width>0
Postcondition:
width_is_set: GetWidth()==width
* double = obj.GetHeight () - Return the length along the y-
axis. Relevant only if GetDimension()>=2
Postcondition:
positive_result: result>0
* obj.SetHeight (double height) - Set the length along the
y-axis. Relevant only if GetDimension()>=2
Precondition:
positive_height: height>0
Postcondition:
height_is_set: GetHeight()==height
* double = obj.GetDepth () - Return the length along the z-
axis. Relevant only if GetDimension()>=3
Postcondition:
positive_result: result>0
* obj.SetDepth (double depth) - Return the length along the
z-axis. Relevant only if GetDimension()>=3
Precondition:
positive_depth: depth>0
Postcondition:
depth_is_set: GetDepth()==depth
* obj.SetImplicitFunction (vtkImplicitFunction ) - Specify
the implicit function to use to generate data.
* vtkImplicitFunction = obj.GetImplicitFunction () - Specify
the implicit function to use to generate data.
* obj.SetOutputScalarType (int ) - Set what type of scalar
data this source should generate.
* int = obj.GetOutputScalarType () - Set what type of scalar
data this source should generate.
* obj.SetOutputScalarTypeToDouble () - Set what type of
scalar data this source should generate.
* obj.SetOutputScalarTypeToFloat () - Set what type of
