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.

CutGeometry is available for COVISE version 4.5 and higher. It's tested on all available platforms.

Parameters

Name	Type	Description
method	Choice	cut geometry based on data or based on geometry
distance	FloatScalar	distance of plane
normal	FloatVector	normal of plane
data_min	FloatScalar	smallest data value, polygons with smaller values will be removed
data_max	FloatScalar	biggest data value, polygons with bigger values will be removed
invert_cut	Boolean	invert selected polygons?
strict_selection	Boolean	one vertex out of bound is enough to erase polygon

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.
