IsoLines

IsoLines creates isolines in a polygon. You can use a range of isovalues.

IsoLines is available for all COVISE versions and supported platforms.

Parameters

Name Type Description
from Scalar IsoLines uses a range of isovalues. from is the beginning of this range.
to Scalar End of the range of isovalues.
step Scalar The range of isovalues is divided up into several values. step is the difference between these values.
distance Scalar Distance between plane of the polygon and the isolines. This parameter can be used to display simultaneously data on the polygons and all isolines. If you use positive distances the isolines are moved "behind" the polygon. Therefore you should use negative values in general.

Input Ports

Name Type Description
requiredgeo_in Polygons Input polygons
requireddata_in Float Data on these polygons

Output Ports

Name Type Description
outputlines_out Lines Computed Isolines
outputdata_out Float Data on the isolines

Examples

Figure: covise/net/examples/IsoLines.net
IsoLinesMap.png

RWCovise1 reads in the grid. RWCovise2 reads temperature data. CuttingSurface creates a cutting plane and temperature data on it. We use IsoLines to show borders between areas of the same value. Therefore we use the whole range of data values and change the step parameter until the visualisation is satisfactory. The parameter distance is set to -0.005. So the isolines are close to the cutting plane but not in it.
