[vtkusers] Empty mesh from Delaunay3D

[Rakesh Patil]

 hi...as far as my knowledge is concerned, unstructured grid must contain atleast one cell.. Thus, you need to create a cell array of containing min one element and allocate it to the UGrid.. then set the points.. see this examplehttp://public.kitware.com/cgibin/viewcvs.cgi/*checkout*/Rendering/Testing/Cxx/TestOrderedTriangulator.cxx?root=VTK&contenttype=text/plainThanksRegardsRakesh Patil Original message From:superzz< jxdwzlf at yahoo.com.cn >Date: 10 Mar 10 14:16:45Subject:[vtkusers]Empty mesh from Delaunay3DTo: vtkusers at vtk.orgHelloI get an empty mesh from Delaunay3D. vtkPoints is used as source data. Am Iusing Delaunay3D in a wrong way?Thanks!superZZvtkPoints pts = new vtkPoints();//points xyzpts.InsertPoint(0, 188, 377, 1);pts.InsertPoint(1, 195, 385, 1);pts.InsertPoint(2, 207, 393, 1);pts.InsertPoint(3, 221, 395, 1);pts.InsertPoint(4, 230, 396, 1);pts.InsertPoint(5, 241, 396, 1);pts.InsertPoint(6, 211, 399, 1);pts.InsertPoint(7, 223, 399, 1);pts.InsertPoint(8, 201, 392, 1
