Tiling Response

Hello Calculus 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.

It is very interesting how a small piece of a photograph can turn into what we were trying to decipher, the tiled window. In fact, my computer teacher showed me how to degrade pictures, but I just guess I wasnt aware that the same pictures could transform into degraded,small blocks. When I was trying to answer Mr. A. guestion I was also looking to see if the colors had patterns. My question is then, if the pattern is caused by nature because of a specific image, then does that mean the colors have no specific pattern, just the pattern of the image, if indeed the image has a pattern?Is it confusing? hehe. Or well the pattern could be found whithin the program that degrades the images?Or not?

I like the idea that the pattern is generated from the computer process of degrading the image! However, I think there is no pattern, simply chance and it results in a pleasing combination of colors and randomness.

Mapgirl,
Thank you so much for responding to our blog. It was very interesting to find out that the degrading tiling was not any sort of sequence. I was sure that it was. Where did the "degradado azul" come from? The sky? And do you think that there is any way to find out?
