vtkFastSplatter

Section: Visualization Toolkit Imaging Classes

Usage

vtkFastSplatter takes any vtkPointSet as input (of which vtkPolyData and vtkUnstructuredGrid inherit). Each point in the data set is considered to be an impulse. These impulses are convolved with a given splat image. In other words, the splat image is added to the final image at every place where there is an input point.

Note that point and cell data are thrown away. If you want a sampling of unstructured points consider vtkGaussianSplatter or vtkShepardMethod.

Use input port 0 for the impulse data (vtkPointSet), and input port 1 for the splat image (vtkImageData)

.SECTION Bugs

Any point outside of the extents of the image is thrown away, even if it is close enough such that it's convolution with the splat image would overlap the extents.
