Hi all, <br><br>I have a triangular mesh obtained using itk and now, already on vtk, I want to use the modified BSPTree as a line intersection method. The mesh I am using has a big hole.<br>The function <a href="http://www.vtk.org/doc/nightly/html/classvtkModifiedBSPTree.html#a3a03f352030b2aeb73239aee02037deb" target="_blank">IntersectWithLine</a> (const <a href="http://www.vtk.org/doc/nightly/html/vtkVectorOperators_8h.html#a45c855d65dd0e2b57b08024500ff9159" target="_blank">double</a> p1[3], const <a href="http://www.vtk.org/doc/nightly/html/vtkVectorOperators_8h.html#a45c855d65dd0e2b57b08024500ff9159" target="_blank">double</a> p2[3], const <a href="http://www.vtk.org/doc/nightly/html/vtkVectorOperators_8h.html#a45c855d65dd0e2b57b08024500ff9159" target="_blank">double</a> tol, <a href="http://www.vtk.org/doc/nightly/html/classvtkPoints.html" target="_blank">vtkPoints</a> *points, <a href="http://www.vtk.org/doc/nightly/html/classvtkIdList.html" target="_blank">vtkIdList</a> *cellIds) says nothing about assuming that the surface has to be closed, but when I do some search about line-mesh intersections using vtk methods it seems that a closed mesh is mandatory. Do I need to close it? <br>
