Hello,

I want to visualize a rectilinear grid that can be transformed by a linear transformation and then clipped by a general plane. Clipping by such plane means filter out all grid cells not belonging to a half-space defined by the clipping plane.

So far I use following pipeline:

1. vtkRectilinearGrid
2. vtkTransformFilter
3. vtkExtractGeometry (clipping by vtkImplicitFunction representing the clipping plane)

But for bigger grids the rendering is quite slow. Is there a better (meaning faster) way how to visualize such grid subset?
