Out of Bounds World automatically NOT drawn?

[kingcools]

hi,

short question:

When something of my 2d World (e.g. a tilemap) is drawn and parts of it are out of the windows view are they still drawn? So do i still have to check how much to draw of my world (would be strange now that i think about it)?

I remember doing a 2d worldeditor in QT and at first i drew my whole tilemap with like 200x200 dimension, even though only like 20x20 was visible at a time which made my program rather slow.

SFML does not provide automatic draw culling. This is something you need to implement yourself.

Okay, thanks!

Note that your graphics card typically processes all vertices, and then only emits fragments for visible portions (ie. a fragment shader would not run for occluded pixels). Your main bottleneck might therefore rather be in the large amount of data (the entire tilemap's worth of vertices) that is transferred each frame.
