I started reading Robert Bosch book "Opt Art: From Mathematical Optimization to Visual Design" and wanted to play a little bit with some of the concepts related with the first chapter, The Truchet Tiles. Meanwhile I was working in this I made a little image processing stuff with p5.js using the tile concepts and the mesuarement of brightness pixels to make it visible.
Its really easy to use, you just need to upload a picture, select the size of the tile and the order of them then you can right click the image and save it.
Im still trying to figuring out how to resize the pictures properly because theres a kind of process/time/performance issue if the image is big and that. The default size is the width and height of the picture multiplied by *8 if is horizontal and vertical. If someone knows a better way to make this a good size, tell me please. I will add it.
