Hi everybody,<br><br>I want to get normal vector of point around a cell/polygon in my vtk class. <br>I suppose that everypoint has normal vector as well which is calculated from cell's normal vector around that point.<br>
<br><br>I dont know if vtkPolyDataNormals can do that because my vtk class is derived from vtkDataSetToPolyData.<br>What I know is vtkPolyDataNormals can take only polygonal data input not vtkDataSet input.<br><br>Thanks in advance.
<br><br>regards,<br>sugeng<br clear="all"><br>
