d_stranz,

So how is it going for you now with VTK? How easy it is to integrate it with Qt? Have you already managed to do for example some basic Cosine plot with it in a Qt application? Could you share some details if you did, or links to guides maybe? because the guides I see online are not much into specifically doing it with Qt programs.

Also, how efficient you think is openGL utilized in VTK? And is there big overhead in upper layer code?
