Detailed Description

represents an object (geometry & properties) in a rendered scene.

Date:

2000/12/10 20:08:29

Revision:

1.87

vtkActor is used to represent an entity in a rendering scene. It inherits functions related to the actors position, and orientation from vtkProp. The actor also has scaling and maintains a reference to the defining geometry (i.e., the mapper), rendering properties, and possibly a texture map. vtkActor combines these instance variables into one 4x4 transformation matrix as follows: [x y z 1] = [x y z 1] Translate(-origin) Scale(scale) Rot(y) Rot(x) Rot (z) Trans(origin) Trans(position)

Member Function Documentation

virtual const char* vtkActor::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 vtkProp3D. Reimplemented in vtkFollower, vtkLODActor, vtkMesaActor, and vtkOpenGLActor.

int vtkActor::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 vtkProp3D. Reimplemented in vtkFollower, vtkLODActor, vtkMesaActor, and vtkOpenGLActor.

virtual int vtkActor::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 vtkProp3D. Reimplemented in vtkFollower, vtkLODActor, vtkMesaActor, and vtkOpenGLActor.

vtkActor* vtkActor::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 vtkProp3D. Reimplemented in vtkFollower, vtkLODActor, vtkMesaActor, and vtkOpenGLActor. Referenced by vtkActorCollection::GetLastActor(), and vtkActorCollection::GetNextActor().

void vtkActor::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 vtkProp3D. Reimplemented in vtkFollower, and vtkLODActor.

vtkActor* vtkActor::New (    )  [static]

Creates an actor with the following defaults: origin(0,0,0) position=(0,0,0) scale=(1,1,1) visibility=1 pickable=1 dragable=1 orientation=(0,0,0). No user defined matrix and no texture map. Reimplemented from vtkProp. Reimplemented in vtkFollower, vtkLODActor, vtkMesaActor, and vtkOpenGLActor.

virtual void vtkActor::GetActors (  vtkPropCollection *    )  [virtual]

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. Reimplemented from vtkProp.

virtual int vtkActor::RenderOpaqueGeometry (  vtkViewport *    viewport )  [virtual]

Support the standard render methods. Reimplemented from vtkProp. Reimplemented in vtkFollower, and vtkLODActor.

virtual int vtkActor::RenderTranslucentGeometry (  vtkViewport *    viewport )  [virtual]

Reimplemented from vtkProp. Reimplemented in vtkFollower.

virtual void vtkActor::Render (  vtkRenderer *    ren, vtkMapper *    mapper )  [inline, virtual]

This causes the actor to be rendered. It in turn will render the actor's property, texture map and then mapper. If a property hasn't been assigned, then the actor will create one automatically. Note that a side effect of this method is that the pipeline will be updated. Reimplemented in vtkLODActor, vtkMesaActor, and vtkOpenGLActor. Definition at line 98 of file vtkActor.h.

void vtkActor::ShallowCopy (  vtkProp *    prop )  [virtual]

Shallow copy of an actor. Overloads the virtual vtkProp method. Reimplemented from vtkProp3D. Reimplemented in vtkFollower, and vtkLODActor.

void vtkActor::ReleaseGraphicsResources (  vtkWindow *    )  [virtual]

Release any graphics resources that are being consumed by this actor. The parameter window could be used to determine which graphic resources to release. Reimplemented from vtkProp. Reimplemented in vtkLODActor.

void vtkActor::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* vtkActor::GetProperty (    )

void vtkActor::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* vtkActor::GetBackfaceProperty (    )

virtual void vtkActor::SetTexture (  vtkTexture *    )  [virtual]

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.

virtual vtkTexture* vtkActor::GetTexture (    )  [virtual]

virtual void vtkActor::SetMapper (  vtkMapper *    )  [virtual]

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.

virtual vtkMapper* vtkActor::GetMapper (    )  [virtual]

Returns the Mapper that this actor is getting its data from.

void vtkActor::GetBounds (  float    bounds[6] )  [inline]

Get the bounds for this Actor as (Xmin,Xmax,Ymin,Ymax,Zmin,Zmax). (The method GetBounds(float bounds[6]) is available from the superclass.) Reimplemented from vtkProp3D. Definition at line 141 of file vtkActor.h.

float* vtkActor::GetBounds (    )  [virtual]

Get the bounds for this Prop as (Xmin,Xmax,Ymin,Ymax,Zmin,Zmax). in world coordinates. NULL means that the bounds are not defined. Reimplemented from vtkProp3D.

virtual void vtkActor::ApplyProperties (    )  [inline, virtual]

Apply the current properties to all parts that compose this actor. This method is overloaded in vtkAssembly to apply the assemblies' properties to all its parts in a recursive manner. Typically the use of this method is to set the desired properties in the assembly, and then push the properties down to the assemblies parts with ApplyProperties(). Definition at line 150 of file vtkActor.h.

virtual void vtkActor::Update (    )  [virtual]

Update visualization pipeline and any other parts of actor that are necessary.

unsigned long int vtkActor::GetMTime (    )  [virtual]

Get the actors mtime plus consider its properties, texture and usermatrix if set. Reimplemented from vtkObject.

virtual unsigned long vtkActor::GetRedrawMTime (    )  [virtual]

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. Reimplemented from vtkProp.

virtual void vtkActor::InitPartTraversal (    )  [virtual]

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).

virtual vtkActor* vtkActor::GetNextPart (    )  [virtual]

virtual int vtkActor::GetNumberOfParts (    )  [virtual]

void vtkActor::SetProperty (  vtkProperty &    lut )  [inline]

For legacy compatibility. Do not use. Definition at line 176 of file vtkActor.h.

void vtkActor::SetBackfaceProperty (  vtkProperty &    lut )  [inline]

Definition at line 178 of file vtkActor.h.

void vtkActor::operator= (  const vtkActor &    )  [inline, protected]
