CutGeometry

CutGeometry cuts geometry objects: Lines, Polygons and TriangleStrips. The part which sould be cut away is defined through a plane. This is used to make the inner parts of geometry objects visible.

RWCovise reads in the computational grid of a channel with two inlets. DomainSurface computes the outer surface of the channel. CutGeometry cuts the upper side of the channel.

The following image shows the cutted channel in the renderer.
