class	vtkPolyDataToImageData

Source code

// This filter takes a vtkPolyData input and produces a vtkImageData output.
// It is intended to take a closed surface mesh and produce a binary rasterization.
// 
// Options are:
//
//  Border: optional border around object (useful for isosurfacing)
//
//  Spacing: output image spacing
//
//  SampleDistance: sample distance for point sampling along surface
//                  if you get a blank/full image, try reducing this value
//
//  InitialBallSize: dilate/erode ball size for morphological closing
//                  if you get a blank/full image, try increasing this value
//
//  FinalBallSize: dilate/erode ball size step at the end
