VTK Poisson Reconstruction

* Visual Studio 빌드
 - 소스: https://github.com/daviddoria/PoissonReconstruction
 - kazhdan 원본 소스(https://github.com/mkazhdan/PoissonRecon)를 vtk에서 작동가능하게 함
 - VTK Poisson Reconstruction을 작동하기 위해서는 vertex normal이 계산되어야 함
 - vtk 9.3에서는 vtkPCANormalEstimation 이용해서 vertex normal 생성
 - vtk 9.3 이전 버전에서는 vtkPolyDataNormals 이용해서 vertex normal 생성

 - vertex normal 자료형은 vtkDoubleArray가 아닌 vtkFloatArray으로 해야 VTK Poisson Reconstruction 작동함
