<div dir="ltr">Hi<div>A while back (2015) a similar query  was posted. I have version 7.1 of the Vtk src and am interested in only</div><div>the modules viz. vtkIOImport, vtkIOEnsight which should be void of any OpenGL dependency (based on my understanding). I tried following the solution suggested in the thread but without much success. I am possibly missing something. Any pointers would be appreciated.</div><div>
