[vtkusers] Normal Direction of point set

Sun Mar 12 08:12:15 EDT 2017

Thank you Jon Haitz for your prompt answer. But, in my case I would like to use two different versions of VTK: 5.10.1 and 7.1.0.

How can I indicate it in CMakeLists file ?

Kind regards,

These variables are set by VTK when running CMake.

For VTK 5.10.0, for example, VTK_MAJOR_VERSION would be 5, and VTK_MINOR_VERSION  would be 10.

In your code you would use them as explained here [1].

Dear Jon Haitz Legarreta,

Could you please help me to define the VTK_MAJOR_VERSION, VTK_MINOR_VERSION.

My own CMakeLists is writting as follow :

--------------------------------------

cmake_minimum_required(VERSION 2.6)
PROJECT(main)

IF(NOT VTK_BINARY_DIR)
FIND_PACKAGE(VTK)
IF(NOT VTK_DIR)
  MESSAGE(FATAL_ERROR "Please set VTK_DIR.")
ENDIF(NOT VTK_DIR)
INCLUDE(${VTK_USE_FILE})
ENDIF(NOT VTK_BINARY_DIR)
FIND_PACKAGE ( ITK)
IF ( ITK_FOUND)
INCLUDE( ${ITK_USE_FILE} )
ENDIF( ITK_FOUND)
--------------------------------------

The VTK_MINOR_VERSION  is 5.10.1
The  VTK_MAJOR_VERSION is 7.1.0.

Thank you in advance.

If you mean using parts of a given version (say 5.10.1) and using some other parts of another version (say 7.1), chances are that this approach results in unexpected behavior to say the at least (if you even try). Regardless of whether the toolkit or external library used is VTK or not, that approach is not advisable.

The class at issue may depend on other classes or features not present in earlier versions, so you'd better use 7.1 if you need the class.

You can perfectly have as many VTK versions as needed installed/built in the same machine.

You can use the VTK_MAJOR_VERSION, VTK_MINOR_VERSION, etc. flags in your project if you want to use the feature depending on the availability of the VTK version your project links against. At least if the feature is not critical.

Mine is 5.10.1. Can I get two different versions of VTK in the same windows and used for the same project? Is there any other way please?

Dear Mr Bill,

Thank you for your prompt answer. I tried to adopt vtkPCANormalEstimation. But, I could not find the vtkFiltersPointsModule.h.

see the example:
