I want to know if it's possible to simply display an image fullscreen. For example, I have two images. One has the size 1900x500 and the other 2440x940.
I'm developing for mobile devices, so those resolutions are way to big compared to the resolutions most phones have right now. So that's why I'd like to "resize" those images so they entirely fit on the screen, keeping its aspect ratio.
But I have no idea how to do this. All I can find is how to convert an image to a texture and display that on two triangles. But I assume that it should be possible to simply display an image on the screen without the need of a 3d object
If so, then how can I do this?
