Tipsios

we'd better to use SSD to compile source code instead HDD. So put source code in C folder on windows.git

use multiple processor to compile with /MP options.github

install pcl by installer

install pcl to `C:Program FilesPCL 1.8.1`

choose to install OpenNI2 to `C:Program FilesPCL 1.8.13rdPartyOpenNI2`

this process will add 4 system env.

we need to compile vtk to replace `C:Program FilesPCL 1.8.13rdPartyVTK`

    mkdir build && cd build 
    cmake-gui ..複製代碼

configure generator to Visual Studio 14 2015 Win64 with options

unzip VTKData-8.1.0.zip and copy MD5 to VTK-8.1.0/build/ExternalData/Objects/MD5

(1) With VTK = 8.1.0:

VTK_Group_Qt  ON複製代碼

configure again, and then QT_QMAKE_EXECUTABLE and VTK_QT_VERSION will appear.

(2) we need to change VTK_QT_VERSION from 4 to 5.

(3) change VTK_RENDERING_BACKEND from OpenGL to OpenGL2.

VTK_RENDERING_BACKEND OpenGL2 # by default OpenGL複製代碼

(4) set install path `C:Program FilesVTK`

CMAKE_INSTALL_PREFIX  C:/Program Files/VTK  複製代碼

we need write privileges to install to `C:Program FilesVTK`

otherwise, when we install, error will occur:

1>  -- Install configuration: "Release"

(5) we should also notice BUILD_SHARED_LIBS

(6) add /MP for multiple processor compile

    CMAKE_CXX_MP_FLAG ON
    CMAKE_CXX_MP_NUM_PROCESSORS 8複製代碼

(7) Configure and warning will occur

      of CMake.複製代碼
The cmake-policies(7) manual explains that the OLD behaviors of all

compile

If everything goes well, then generate VTK.sln.

Open VTK.sln in vs2015 and build with Release X64.

install vtk

choose INSTALL and generate , and VTK will be installed to `C:Program FilesVTK`.

Notice for QVTKWidgetPlugin and copy dll and lib to `C:Program FilesVTK`.

  • dll: copy C:compileVTK-8.1.0buildbinReleaseQVTKWidgetPlugin.dll to C:Program FilesVTKbinQVTKWidgetPlugin.dll
  • lib: copy C:compileVTK-8.1.0buildlibReleaseQVTKWidgetPlugin.libto C:Program FilesVTKlibQVTKWidgetPlugin.lib

we should also notice that dll has been copied to C:Program FilesVTKpluginsdesignerQVTKWidgetPlugin.dll

copy vtk to pcl

copy vtk from C:Program FilesVTK` to C:/Program Files/PCL 1.8.1/3rdParty/VTK` to replace old one.

install QVTKWidgetPlugin

copy C:Program FilesVTKpluginsdesignerQVTKWidgetPlugin.dll toC:QtQt5.7.15.7msvc2015_64pluginsdesigner

start vs2015 again, view mainwindow.ui in Qt Designer.

Now QVTKWidget will occur.
