void ProcessSelectorPixelBuffers(vtkHardwareSelector *sel, std::vector< unsigned int > &pixeloffsets, vtkProp *prop) override
allows a mapper to update a selections color buffers Called from a prop which in turn is called from ...
std::vector< std::vector< unsigned int > > PickPixels
bool HasTranslucentPolygonalGeometry() override
Based on emissive setting.
void Render(vtkRenderer *ren, vtkActor *act) override
This calls RenderPiece (in a for loop if streaming is necessary).
vtkExecutive * CreateDefaultExecutive() override
We need to override this method because the standard streaming demand driven pipeline may not be what...
std::vector< vtkOpenGLPointGaussianMapperHelper * > Helpers
void ReleaseGraphicsResources(vtkWindow *) override
Release any graphics resources that are being consumed by this mapper.
void RenderPiece(vtkRenderer *, vtkActor *) override
Implemented by sub classes.
void CopyMapperValuesToHelper(vtkOpenGLPointGaussianMapperHelper *helper)
void ComputeBounds() override
Need to loop over the hierarchy to compute bounds.

static vtkOpenGLPointGaussianMapper * New()
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkOpenGLPointGaussianMapperHelper * CreateHelper()
int FillInputPortInformation(int port, vtkInformation *info) override
Need to define the type of data handled by this mapper.
