Detailed Description

State used by vtkOpenGLCellGridMapper during rendering.

This is a vtkCellGridQuery subclass that mappers can use to draw cells into a renderer using an actor and, subsequently, to release resources.

Note that this request has two modes: it will either instruct responders to draw cells (IsReleasingResources == false) or instruct responders to release OpenGL objects for a particular window (when IsReleasingResources == true). Responders must call GetIsReleasingResources() and only perform one task or the other, depending on the returned value.

Member Typedef Documentation

◆ Superclass

Definition at line 65 of file vtkOpenGLCellGridRenderRequest.h.

Member Enumeration Documentation

◆ RenderableGeometry

An enumeration of which shapes to render.

A cell may be represented by its interior and/or its boundaries of any dimension. These enumerants indicate the dimension of shape to render as a representation of the cell.

The default is to render the cell's shape itself (if possible) and any sides for which arrays exist. Note that the cell-grid mapper does not currently support volume rendering, so VOLUME is ignored; if you wish to render volumetric cells, you must run the vtkCellGridExtractSurface filter to generate side-set arrays for boundaries of interest.

◆ IsTypeOf()

static vtkTypeBool vtkOpenGLCellGridRenderRequest::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkOpenGLCellGridRenderRequest::IsA ( const char *  name)
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 vtkCellGridQuery.

◆ SafeDownCast()

static vtkOpenGLCellGridRenderRequest * vtkOpenGLCellGridRenderRequest::SafeDownCast ( vtkObjectBase o)
static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkOpenGLCellGridRenderRequest::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkCellGridQuery.

◆ NewInstance()

◆ New()

static vtkOpenGLCellGridRenderRequest * vtkOpenGLCellGridRenderRequest::New ( )

◆ PrintSelf()

void vtkOpenGLCellGridRenderRequest::PrintSelf ( std::ostream &  os,
vtkIndent  indent 
)
override

◆ SetMapper()

virtual void vtkOpenGLCellGridRenderRequest::SetMapper ( vtkOpenGLCellGridMapper mapper)
virtual

Set/get the mapper which owns this request (so responders can inspect its configuration).

Note that the render request does NOT increase the reference count of the mapper (thus it does not take ownership). This is because the request is owned by the mapper and we do not want to create a reference loop.

◆ GetMapper()

virtual vtkOpenGLCellGridMapper * vtkOpenGLCellGridRenderRequest::GetMapper ( )
virtual

◆ SetActor()

virtual void vtkOpenGLCellGridRenderRequest::SetActor ( vtkActor actor)
virtual

Set/get the actor which responders should use to draw cells.

Note that the render request does NOT increase the reference count of the actor (thus it does not take ownership). This is to avoid creating a reference loop.

◆ GetActor()

virtual vtkActor * vtkOpenGLCellGridRenderRequest::GetActor ( )
virtual

◆ SetRenderer()

virtual void vtkOpenGLCellGridRenderRequest::SetRenderer ( vtkRenderer renderer)
virtual

Set/get the renderer responders should use to draw cells.

Note that the render request does NOT increase the reference count of the renderer (thus it does not take ownership). This is to avoid creating a reference loop.

◆ GetRenderer()

virtual vtkRenderer * vtkOpenGLCellGridRenderRequest::GetRenderer ( )
virtual

◆ SetWindow()

virtual void vtkOpenGLCellGridRenderRequest::SetWindow ( vtkWindow window)
virtual

Set/get a window (used when IsReleasingResources is true).

Note that the render request does NOT increase the reference count of the window (thus it does not take ownership). This is to avoid creating a reference loop.

◆ GetWindow()

virtual vtkWindow * vtkOpenGLCellGridRenderRequest::GetWindow ( )
virtual

◆ GetShapesToDraw()

virtual char vtkOpenGLCellGridRenderRequest::GetShapesToDraw ( )
virtual

Set/get what geometric data to draw for each cell.

The DEFAULT is currently equivalent to ALL. Note that any combination of RenderableGeometry enumerants is accepted.

◆ SetShapesToDraw()

virtual void vtkOpenGLCellGridRenderRequest::SetShapesToDraw ( char  )
virtual

◆ Initialize()

void vtkOpenGLCellGridRenderRequest::Initialize ( )
overridevirtual

This is invoked before processing any cell types during a render.

Reimplemented from vtkCellGridQuery.

◆ Finalize()

void vtkOpenGLCellGridRenderRequest::Finalize ( )
overridevirtual

This is invoked after processing all cell types during a render.

Reimplemented from vtkCellGridQuery.

◆ GetIsReleasingResources()

virtual bool vtkOpenGLCellGridRenderRequest::GetIsReleasingResources ( )
virtual

Set/get whether the request should render (false) or release resources (true).

The latter should be performed as a separate query after rendering.

Note that after a successful call to Query with IsReleasingResources set to true, the Finalize() method will reset IsReleasingResources to false, which results in the request being marked modified.

◆ SetIsReleasingResources()

virtual void vtkOpenGLCellGridRenderRequest::SetIsReleasingResources ( bool  )
virtual

◆ GetState()

template<typename StateType >
StateType * vtkOpenGLCellGridRenderRequest::GetState ( vtkStringToken  cellType)
inline

Return a state object of the given type.

This method is intended for responders to store data with the request.
