Why is there visible angular distortion when you zoom in? It shouldn't happen if you do the Droste effect correctly, like this: https://www.youtube.com/watch?v=

- pmelendez 12y agoMy bet is that he is using a continuos transformation and the guys who first did this (at least as far as I know) reproduced and completed the original transformation grid that Escher did. http://escherdroste.math.leidenuniv.nl/index.php?menu=symmetry http://escherdroste.math.leidenuniv.nl/index.php?menu=symmet... The transformation is a conformal map so it should not deform angles. Other explanation is that the fragment shader is losing information in the process and that float numbers are not precise enough. Still this is very impressive
- jameshart 12y agoThere's a camera wobble effect he's applying that actually moves the camera slightly from side to side - might account for what you're seeing? On the shadertoy code (https://www.shadertoy.com/view/Mdf3zM https://www.shadertoy.com/view/Mdf3zM), remove the #define WOBBLE and you should see a clean zoom.
