I'm using a version of VTK 5.10. I'm rendering some numbers on the window
but they don't display well (the screen shot attached I wrote one in red
but it doesn't render completely). I suspect that the antialiasing doesn't
work well (maybe I'm wrong here).
So I tried to disable the antialiasing and compare the result:
prenderer->GetRenderWindow()->SetMultiSamples(0); // 0 means turn OFF
But the result still the same. Have u any idea about this issue?
here are two screen shots. As we see here, the number '11' and '12' are not fully rendered.
These problems were fixed in the rewrite of VTK's text rendering backend that occurred around the release of version 6.0. A newer version of VTK should fix this, but let us know if you still see this in version 6 or later.
