Tiling Response

Hello Precalculus Students!
I was reading your class blog and found the discussion of the "Degradado Azul" pattern interesting. I had an idea about how I would create the pattern using tools of my profession. I'm a cartographer - which means I make maps. I use computers almost entirely to make maps and use many different programs. (You can see some of my maps here...)

Here's how I would make the pattern for the tiles. My example is a little different looking, but the concept is the same.

First I would start with this picture:




and take a small sample of it (like the area shown in red).
If you take this small sample and paste it into a new image and stretch it you end up with something like this:


Basically this is just an easy way to get the color gradient that you want. You can do other things to create the gradient also.

Next I used the pixelate filter to create a pixelated image (made of up large squares) and the image looks like this (I also rotated the image to be more like Mr. Alcantara's example):



At this point you can use it as a guide to create a tiled pattern. So my answer to Mr. Alcantara's question

"How was this tile pattern generated? "

is... from nature!

Thanks for letting me join in on your discussion.

Wow!! I never would have imagined it could be done that way, it was great that you could show us that technic, thank you.

Ann, thank you for showing us how to create a tile like that. That's awesome! And it is really interesting! Thanks

Apriciate that,nice job.Surely you dominate computer programs.I had never herd about pixelate filters.

Ann, I’m glad you post such an explanation for tiling patterns because I had noticed that it caused some feelings or sensations when observed, but I never thought that it came from pictures as these ones. It is impressive how you can transform it in computer programs to such patterns.
