PolyDataMapper using OpenGL to render.
void ComputeBounds() override
Called in GetBounds().
represents an object (geometry & properties) in a rendered scene
Definition: vtkActor.h:45
static vtkOpenGLPolyDataMapper * New()
virtual vtkExecutive * CreateDefaultExecutive()
Create a default executive.
Store vtkAlgorithm input/output information.
vtkTypeUInt32 vtkMTimeType
Definition: vtkType.h:300
mapper for composite dataset consisting of polygonal data.
std::vector< vtkPolyData * > GetRenderedList()
Accessor to the ordered list of PolyData that we end last drew.
record modification and/or execution time
Definition: vtkTimeStamp.h:32
Rendering attributes for a multi-block dataset.
abstract specification for renderers
Definition: vtkRenderer.h:57
Superclass for all pipeline executives in VTK.
Definition: vtkExecutive.h:46
std::map< vtkPolyData *, vtkCompositeMapperHelperData * > HelperDataMap
void SetBlockColor(unsigned int index, double r, double g, double b)
Set/get the color for a block given its flat index.
virtual void InitializeHelpersBeforeRendering(vtkRenderer *vtkNotUsed(ren), vtkActor *vtkNotUsed(act))
This method is called before RenderPiece is called on helpers.
virtual void SetInputArrayToProcess(int idx, int port, int connection, int fieldAssociation, const char *name)
Set the input data arrays that this algorithm will process.
window superclass for vtkRenderWindow
Definition: vtkWindow.h:34
a simple class to control print indentation
Definition: vtkIndent.h:33
std::map< const std::string, vtkCompositeMapperHelper2 * > Helpers
void Render(vtkRenderer *ren, vtkActor *act) override
This calls RenderPiece (in a for loop if streaming is necessary).
vtkSmartPointer< vtkCompositeDataDisplayAttributes > CompositeAttributes
Composite data set attributes.
int FillInputPortInformation(int, vtkInformation *) override
Fill the input port information objects for this algorithm.
std::vector< vtkPolyData * > RenderedList
bool GetIsOpaque() override
Returns if the mapper does not expect to have translucent geometry.
bool ColorMissingArraysWithNanColor
If the current &#39;color by&#39; array is missing on some datasets, color these dataset by the LookupTable&#39;s...
vtkTimeStamp BoundsMTime
Time stamp for computation of bounds.
void ReleaseGraphicsResources(vtkWindow *) override
Release any graphics resources that are being consumed by this mapper.
general representation of visualization data
Definition: vtkDataObject.h:58
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
