[vtk-developers] Compiling VTK with ANGLE

[Patrick Bergeron]

Hey folks,


I am trying to compile VTK with ANGLE on Windows.  (for those who don't know, ANGLE is a GLESv2 and GLESv3 front-end over DirectX).


And I am using VTK in a Qt app.


Since Qt already ships with ANGLE (dll, import library, headers, everything I need), I am trying to use this library (libglesv2.lib) instead of the native opengl32.lib, which loads the native OpenGL driver DLL.


However, I am hitting problems everywhere.



Doing research on the topic, it appears that someone successfully managed - sort of - to get this going in 2017.

Alas, the suggested patch file to the cmake files no longer seems relevant.



Also, as as late, there seems to be new difficulties with doing this, although the post below is with Linux.

Has anyone successfully done this before?


Here are my cmake settings:

   OPENGL_gl_LIBRARY=libGLESv2

   OPENGL_opengl_LIBRARY=libGLESv2     (added variable)

   OPENGL_gles3_LIBRARY=libGLESv2  (added variable)

   OPENGL_GLES3_INCLUDE_DIR=C:\Qt\Qt5.11.0\5.11.0\msvc2015_64\include\QtANGLE   (added variable)

   VTK_OPENGL_USE_GLES=[CHECKED]

   Qt5OpenGL_DIR=C:/Qt/Qt5.11.0/5.11.0/msvc2015_64/lib/cmake/Qt5OpenGL


   VTK_GROUP_ENABLE_Qt=YES

   VTK_GROUP_ENABLE_VTK_RenderingQt=YES


Thanks everyone!
