How to use OpenGL primitives inside a vtkGenericOpenGLRenderWindow ?

I would like to add some OpenGL primitives to my vtk scene (GL_Points) because vtkPoints is too slow to handle, is there a way to do that (without having a native opengl window but a vtkGenericOpenGLRenderWindow) ?

Thanks for your help

Hi, Julien,

There is already a discussion about that here: How to use original OpenGL in VTK program? .

take care,
