Hello,<br><br>I am writing an application in C# that uses the Kitware VTK wrapper, and I've run into a problem.<br>Whenever I try using the IntersectWithLine method in vtkModifiedBSPTree, I get this error:<br><br><b>ERROR: In ..\..\..\..\vtksource-prefix\src\vtksource\Filtering\vtkAbstractCellLocator.cxx, line 106<br>
vtkModifiedBSPTree (09FC5A10): The locator class - vtkModifiedBSPTree does not yet support this IntersectWithLine interface</b><br><br>This is how I initialize the BSP tree:<br><br><span style="color:rgb(0,0,102)"><span style="font-family:courier new,monospace">vtkModifiedBSPTree vBSP = vtkModifiedBSPTree.New();<br>
vBSP.SetDataSet(vSurf.GetOutput());<br>vBSP.BuildLocator();</span></span><br><br>Where <b>vSurf</b> is a vtkSurfaceReconstructionFilter. The output data seems perfectly valid when I render it.<br><br>And this is the line that causes the error:<br>
<br><span style="color:rgb(0,0,102)"><span style="font-family:courier new,monospace">vBSP.IntersectWithLine(p1ptr, p2ptr, intersections, null);</span></span><br><br>Where <b>p1ptr</b> and<b> p2ptr</b> are both IntPtrs generated from double[3] arrays via System.Marshal, and <b>intersections</b> is an empty newly initialized vtkPoints.<br>
<br>I've googled for anything related to this issue to no avail.<br>Is this a missing feature of the Kitware wrapper, or am I doing something wrong? Any help would be greatly appreciated.<br><br clear="all"><div><div>
