How to integrate VTK with OpenGL?

@Jens_Munk_Hansen: I did! :slight_smile:

Here is the cmake command I used to build VTK from source cmake -DVTK_GROUP_ENABLE_Rendering=YES -DVTK_MODULE_ENABLE_VTK_RenderingExternal=YES ..: is there something missing here?

Also I use find_package(VTK COMPONENT RenderingCore RenderingExternal) to compile/link my code base to VTK.

Do you remember where is the GLUT example? Didn’t find it, will re-check…
