Title: Smoothly rendered vertexArrays?
Post by: Vovosunt on May 01, 2012, 09:29:49 pm

I was doing this http://drilian.com/2009/02/25/lightning-bolts/ (http://drilian.com/2009/02/25/lightning-bolts/) using vertexArray for rendering, but I ran into a problem: vertexArrays don't seem to render smoothly.

Is there any way to fix this?

What do you mean? Anti-aliased? Anti-aliasing must be enabled globally when you create the window (in the context settings).

Precisely.
I tried using context setting, but it didn't seem to work. VertexArray stayed alialised.

Nevermind, fixed it.
It seems I just had to setSmooth to true on the texture itself.

But thanks anyway :)

Or not. I can't seem to turn on the antialiasing.
I'm setting up the window as follows:

sf::RenderWindow window(sf::VideoMode(1024,512),"Lights Test",sf::Style::Default,sf::ContextSettings(0,0,4,2,0));

But everything is still aliased.

Any idea on what am I doing wrong?

You said that texture smoothing solved your problem, and now you're trying to enable anti-aliasing. Would you mind explaining what happened in the meantime?

And we still don't know what you want: anti-aliasing (smooth edges) or texture smoothing (smooth textured pixels).

By the way, if you're on Linux, anti-aliasing is broken (see the issue tracker).

Actually, I wanted both, smooth textures and antialiasing.
But mostly antialiasing, because smoothing the texture makes it really blurred out(works well when the sprite is rotated, but otherwise doesn't look too good).
