Original Source: http://feedproxy.google.com/~r/tympanus/~3/FDQVPCkh4Lo/. All we need to do is create a TextureLoader. It keeps our shader a little bit more readable and avoids having a lot of displayed functions that we will not use after all. The first article was about three.js fundamentals. But as you can see, there are still some details missing. So the trick here is to use some math to transform 1 unit to 1 pixel and change the perspective to increase or decrease the distortion effect. This is a trade-off between hardware support, efficiency and quality since linear results normally require at least 12 bits per color channel to prevent color degradation and banding. Furthermore, well use a TextureLoader to load our images and convert them into a texture. With a low For this recreation well be using three.js, and Popmotions Springs.
