View Full Version : Texture Atlas Problem

Is there any way that I can achieve tiles using a texture atlas? I can't figure out how to (ie) be capable to tile a texture that is in the middle of the atlas...
Tks in advance for the tip!

If you're using shaders you could first apply a linear transformation that maps the rectangle in your texture atlas to the [0,1]x[0,1] range and take the fractional value of the result. After that, apply the inverse transformation to the result. Finally, use the resulting value for your texture lookups.

Hummm, I see, but without shaders is there a way?
Im exploring this technique in order to apply it on a mobile device app, no shaders are available and well on 2 texture channel can be used... any suggestions?

No. You can't wrap texture coordinates to arbitrary subrectangles.
