[vtkusers] Help on contourbands and contourlines (2)

[David.Pont at ForestResearch.co.nz]

Hi Patrick,
   I am not familiar with vtkBandedPolyDataContourFilter but I see in the
Tcl example
http://public.kitware.com/cgi-bin/cvsweb.cgi/~checkout~/VTK/Examples/VisualizationAlgorithms/Tcl/BandContourTerrain.tcl

that  SetResolveCoincidentTopologyToPolygonOffset  is used on the mapper
displaying the contour edges. A quick glance at your code shows you are not
using this setting and this could cause the problem you are seeing.

Hi all again,

I am still stucked on the problem of isofilled and isolines contours.
See: http://public.kitware.com/pipermail/vtkusers/2004-March/022780.html

I have prepared 2 tcl examples showing my
impossiblity to get exact line contours over isofilled contours.

See:
http://dods.ipsl.jussieu.fr/brocksce/vtk_bugs/bandcontours/iso_02_annotate.png


All examples in tcl are available at:
http://dods.ipsl.jussieu.fr/brocksce/vtk_bugs/bandcontours/

Any help very welcome.

Patrick
