Detailed Description

GPU implementation of a Line Integral Convolution, a technique for imaging vector fields.

The input on port 0 is an vtkImageData with extents of a 2D image. It needs a vector field on point data. This filter only works on point vectors. One can use a vtkCellDataToPointData filter to convert cell vectors to point vectors.

Port 1 is a special port for customized noise input. It is an optional port. If noise input is not specified, then the filter using vtkImageNoiseSource to generate a 128x128 noise texture.
