To create an instance of class vtkActor, simply invoke its constructor as follows
obj = vtkActor
obj
is an instance of the vtkActor class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkActor = obj.NewInstance ()
vtkActor = obj.SafeDownCast (vtkObject o)
obj.GetActors (vtkPropCollection )
- For some exporters and other other operations we must be
able to collect all the actors or volumes. These methods
are used in that process.
int = obj.RenderOpaqueGeometry (vtkViewport viewport)
- Support the standard render methods.
int = obj.RenderTranslucentPolygonalGeometry (vtkViewport viewport)
- Support the standard render methods.
int = obj.HasTranslucentPolygonalGeometry ()
- Does this prop have some translucent polygonal geometry?
obj.Render (vtkRenderer , vtkMapper )
- Shallow copy of an actor. Overloads the virtual vtkProp method.
obj.ShallowCopy (vtkProp prop)
- Shallow copy of an actor. Overloads the virtual vtkProp method.
obj.ReleaseGraphicsResources (vtkWindow )
- Release any graphics resources that are being consumed by this actor.
The parameter window could be used to determine which graphic
resources to release.
obj.SetProperty (vtkProperty lut)
- Set/Get the property object that controls this actors surface
properties. This should be an instance of a vtkProperty object. Every
actor must have a property associated with it. If one isn't specified,
then one will be generated automatically. Multiple actors can share one
property object.
vtkProperty = obj.GetProperty ()
- Set/Get the property object that controls this actors surface
properties. This should be an instance of a vtkProperty object. Every
actor must have a property associated with it. If one isn't specified,
then one will be generated automatically. Multiple actors can share one
property object.
vtkProperty = obj.MakeProperty ()
- Create a new property suitable for use with this type of Actor.
For example, a vtkMesaActor should create a vtkMesaProperty
in this function. The default is to just call vtkProperty::New.
obj.SetBackfaceProperty (vtkProperty lut)
- Set/Get the property object that controls this actors backface surface
properties. This should be an instance of a vtkProperty object. If one
isn't specified, then the front face properties will be used. Multiple
actors can share one property object.
vtkProperty = obj.GetBackfaceProperty ()
- Set/Get the property object that controls this actors backface surface
properties. This should be an instance of a vtkProperty object. If one
isn't specified, then the front face properties will be used. Multiple
actors can share one property object.
obj.SetTexture (vtkTexture )
- Set/Get the texture object to control rendering texture maps. This will
be a vtkTexture object. An actor does not need to have an associated
texture map and multiple actors can share one texture.
vtkTexture = obj.GetTexture ()
- Set/Get the texture object to control rendering texture maps. This will
be a vtkTexture object. An actor does not need to have an associated
texture map and multiple actors can share one texture.
obj.SetMapper (vtkMapper )
- This is the method that is used to connect an actor to the end of a
visualization pipeline, i.e. the mapper. This should be a subclass
of vtkMapper. Typically vtkPolyDataMapper and vtkDataSetMapper will
be used.
vtkMapper = obj.GetMapper ()
- Returns the Mapper that this actor is getting its data from.
obj.GetBounds (double bounds[6])
- Get the bounds for this Actor as (Xmin,Xmax,Ymin,Ymax,Zmin,Zmax). (The
method GetBounds(double bounds[6]) is available from the superclass.)
double = obj.GetBounds ()
- Get the bounds for this Actor as (Xmin,Xmax,Ymin,Ymax,Zmin,Zmax). (The
method GetBounds(double bounds[6]) is available from the superclass.)
obj.ApplyProperties ()
- Get the actors mtime plus consider its properties and texture if set.
long = obj.GetMTime ()
- Get the actors mtime plus consider its properties and texture if set.
long = obj.GetRedrawMTime ()
- Return the mtime of anything that would cause the rendered image to
appear differently. Usually this involves checking the mtime of the
prop plus anything else it depends on such as properties, textures
etc.
obj.InitPartTraversal ()
- The following methods are for compatibility. The methods will be deprecated
in the near future. Use vtkProp::GetNextPath() (and related functionality)
to get the parts in an assembly (or more correctly, the paths in the
assembly).
vtkActor = obj.GetNextPart ()
- The following methods are for compatibility. The methods will be deprecated
in the near future. Use vtkProp::GetNextPath() (and related functionality)
to get the parts in an assembly (or more correctly, the paths in the
assembly).
int = obj.GetNumberOfParts ()
- The following methods are for compatibility. The methods will be deprecated
in the near future. Use vtkProp::GetNextPath() (and related functionality)
to get the parts in an assembly (or more correctly, the paths in the
assembly).
bool = obj.GetSupportsSelection ()
- WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE
DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS
Used by vtkHardwareSelector to determine if the prop supports hardware
selection.
