a simple class to control print indentation
Definition: vtkIndent.h:40
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
represent and manipulate 4x4 transformation matrices
Definition: vtkMatrix4x4.h:42
virtual void Modified()
Update the modification time for this object.
Superclass for algorithms that produce only polydata as output.
abstract specification for renderers
Definition: vtkRenderer.h:73
extract points that are visible (based on z-buffer calculation)
vtkMatrix4x4 * CompositePerspectiveTransform
~vtkSelectVisiblePoints() override
void SetRenderer(vtkRenderer *ren)
Specify the renderer in which the visibility computation is to be performed.
vtkMTimeType GetMTime() override
Return MTime also considering the renderer.
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
vtkRenderer * GetRenderer()
Specify the renderer in which the visibility computation is to be performed.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
static vtkSelectVisiblePoints * New()
Instantiate object with no renderer; window selection turned off; tolerance set to 0....
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
float * Initialize(bool getZbuff)
Requires the renderer to be set.
bool IsPointOccluded(const double x[3], const float *zPtr)
Tests if a point x is being occluded or not against the Z-Buffer array passed in by zPtr.
