I can convert pointcloud without Polygons or Triangles to a polydata.  
And I want to use vtkCutter to get cross section with a plane, But it failed and report errors as follow

ERROR: In …\Filters\General\vtkOBBTree.cxx, line 1058  
vtkOBBTree (0FA04398): Can’t build OBB tree - no data available!

And I change a method ,which use vtkIntersectionPolyDataFilter ,But it also report errors as follow  
ERROR: In …\Common\ExecutionModel\vtkExecutive.cxx, line 811  
vtkCompositeDataPipeline (0FA35C88): UpdateInformation invoked during another request. Returning failure to algorithm vtkIntersectionPolyDataFilter(1F025978).

And How can I do? Please can you help me? Thanks.
