Hello !<br>I basically have a 3-d point-set which is created from points in the<br>XY plane plus a measured value that is mapped to the z-coordinate.<br>What I tried is doing a 2D-Delaunay and then apply a contour-filter.
<br>However, the contour-filter seems to have no input data. <br><br>Here is the code:<br><br>vtkMccReader reader = new vtkMccReader();<br> reader.SetFileName("D:\\data\\verisoft\\2005-12-13 16'51.mcc
");<br><br> vtkDelaunay2D delaunay = new vtkDelaunay2D();<br> delaunay.DebugOn();<br> <br> delaunay.SetInputConnection(reader.GetOutputPort());<br> // map the data to polygons
<br> //draw contours<br><br> <br> vtkContourFilter contourfilter = new vtkContourFilter();<br> contourfilter.SetInputConnection(delaunay.GetOutputPort());<br> contourfilter.GenerateValues
(5, 0, 0.2);<br> contourfilter.Update();<br><br><br>Please note that it works if I use delaunay only.<br><br>Best regards, Oliver<br><br><br><br>
