Hi all,
Does anybody use vtk with fltk?
How to render vtk object in fltk window?
Looking forward your reply.

Hi, apart from the recommended solution "vtkfltk" I dug into my
sourcecode archive and discovered this prototype I created a few years
ago. This toy may help you start daddling around, but I would stick with
the real "vtkfltk" solution in the long run. Was win32 but should be no
problem on other platforms (use appropriate RenderWindow). link with
vtkCommon.lib vtkRendering.lib vtkGraphics.lib vtkFiltering.lib
