Hasta La Motion!

I am new in nuke. I comming from Aftereffect.
So I want to put words/text in a 3d world and make a camera animation arround them.
What I did:
I made the 3d world(viewer-scanlinerender-scene-camera)
+ I made a card object and as an image I connected a text node.

It looks fine if I look at these text on cards from far away in my camera:)
but when I go closer it looks aweful. If I put anitaliasing high in scanlinerender it looks better, but still not as good as in AE.

So How can I do it, so that when its very close to my camera the edges are still look like in a vector graphics?

Thanks,

Teo
