DS development > Simple texture filtering idea

#90723 - revo - Sun Jul 02, 2006 12:47 am

Hi,
here is demo how to blur textures for a bit, http://revo.pl/texture.zip - press SELECT to change display from normal to blured :)

Idea is very simple, in even frames display everything normally, and in odd frames move u and v coortinates by half. In my opinion effect is very good - what do you think? Source code attached.

Problems with this method:
- screen should be updated @60fps (I don't see any flickering now)
- textures should have 'frame' on two sides to display everything all right if texture is not prepared to be repeated

It's something like this:

Looks good. It's looks like 50% blending, the flickering is unnoticeable.
This trick is so simple, yet works so well. Any game running at 60fps should use this.

I'm glad to see that somebody finally implemented my texture jitter idea. (I would have linked to a search results page, but phpBB's use of POST forbids me to do so.)

Tepples and LunarCrisis suggested it, but mike said it might not work.
