Tileland+ code

Image
Along with an interface update, I added a some language extras.  The native Tileland instructions remain (polygons, colours, and turning) but now I have added the environment instructions to the language.  In particular, I have added clipboard manipulation instructions. Although somewhat hidden, this addition is a metalanguage or a preprocessing language.

It's actually pretty simple when you see an example.  An orange hexagon with a blue square would be 6 o 4 b.  The picture below is a that with a right turn or 6o4b>.  The colour follows the shape so that it has something to colour. Doing that 4 times is just 6o4b>6o4b>6o4b>6o4b>.  Another way to make the pattern is to use the clipboard.  I haven't yet introduced a concept of a cursor yet so the clips come from the entire current code. There are 5 instructions that affect the clipboard: x, v, n, m, and q.  The first, x, simply transfers the current code into the clipboard.  The second, v, adds the first clip to…

New TileLand prototype

Image
This thing is "alpha" code.  It's hot off the press with enough functionality to do interesting things but it's not very polished.  I added the link on the side bar so it'll be easy to access.  The programs come in graphical and textual forms which currently allows you to save your programs by cutting and pasting the text into a place to use later. I stripped down the instructions to one letter to make it more compact and uniform and ease of coding with a keyboard.  I'm sure things will change when I get the time.
There are some annoying bugs that I will fix soon: the one the is most irksome is that my collision detection has some issues that I believe are mainly occurring with triangles but I really haven't done any extensive testing...

Revisiting an unravelling

Image
This is based on an old pattern where I took a clockwise loop of 6 pentagons and combined them with two counter clockwise loops of 3 hexagons resulting in a clockwise loop of pentagons and hexagons. One way to think about the process is to imagine unravelling the loop of pentagons. I used this pattern back in back in 2007 and 2006 but this one has a bit more of a twist.
Perhaps I should come up with a visual of this unravelling. I was hoping I would find one in my blog but I didn't. I should make a better index for this thing...done. In this screen capture, you can see that the outside of the original pentagon loop is now the inside of the composed shape and the inside of the original loop corresponds to the 4 sides of the pentagons the are on the outside of the composed shape. Perhaps I'll play some more with this ‡(double dagger shape which I found its html code here).

Zig, Zag, Zog

Image
Here's just a bit of play before I head to Basketball. I call it zig, zag, zog because there are 3 chunks to the code. Usually, I have a standard zig-zag pattern alternating between to 2 chunks of code. But there are three loops: one if made of zig and zag, another is made from zig and zog, and the final is made of zag and zog. Not too deep but still nice with my new SVG output.
This picture of the code shows a as zig, b as zag, and c as zog. It's pretty clear that a calls b which calls a making a zig-zag loop; and similarly that b calls c which calls b making the zag-zog loop. But the zig-zog loop takes a bit of though--in the code for b since it calls both an a and a c. But essentially c results in a cbcbcb loop with that last b also calling an a so the first c essentially calls an a. Similarly a essentially calls an c thus resulting in the zig-zog loop. There's a bit of twisting calling going on.

Google driving...

This apparently won't work by September 2016--so I'm migrating my files to dropbox... Well, I think I finally worked out how to easily get my files in my blog. It was a bit hairy to find the magic link googledrive.com/host/0BwD1YaggiIIAY1gxNEJEa2JKNlU. I should have guessed, right? My problem was playing with drive.google.com, fileview, #folder, file/d and many other combinations. But probably most of my issues were related to picassa web not storing my svg files... Now I can get to what I actually want to do...talk about polygons!!! For simple patterns like these, I'll start including the PolygonR&D programs along side. This quilt like pattern has only one chunk of code. I used a few colours so that it would be easier to unravel how it works. Although it is constructed with hexagons, squares, and triangles, the white spaces are probably the more interesting features. The Xs and the compass-like (called compass rose or windroses) gaps probably offer more interest…
