When you think of WebGL you probably think of amazing 3D demos, games, and things like that. You probably never think of slideshow transitions. Gaëtan Renaudeau (@greweb) has put WebGL to use for just that in this small GLSL-Transition experiment.
Assuming you have a WebGL capable browser (which is probably a safe assumption here) the transitions are buttery smooth. And the tool let’s you select and effect – ripple, page turn and wind to name a few – as well as the duration, delay and easing. It’s probably overkill for your next image slideshow, but still worthing checking out. For full documentation and all the source, check it out on github too.
