SFML 2.0 - AntiAliasing
« on: July 28, 2012, 05:21:51 am »
Hi again! I have next greenhorn question. What's happened to AntiAliasing i SFML 2.0? I remember that in 1.6 version of SFML I didn't have any problems. I tried to add these lines before RenderWindow:
Quote
sf::ContextSettings settings;
settings.antialiasingLevel = 8;
.. Nothin' happened. :D

Attached photos (first not rotated arrow sprite, second rotated one):

Thanks. :)

You might need to set your sprite to use a smoothed texture. sf::Texture has a method called setSmooth(...). You can read about it more in the SFML documentation.
SFGUI # SFNUL # GLS # Wyrm <- Why do I waste my time on such a useless project? Because I am awesome (first meaning).

Indeed, antialiasing smoothes the geometry edges, not the textures pixels.

Thank you! Now my arrow is smoothed perfectly (see screenshot). Tell me, is it possible to determine 'setSmooth(true)' as default value for any new loaded texture (like in 1.6)?  ;D

If it were a good idea, Laurent wouldn't have changed it for SFML 2.

In my opinion, the default behavior should be to render images 1:1, without special filters. With the old semantics, there have been loads of forum threads because images were drawn in a distorted way.
