Wallpaper trap

A trap class which allows to draw patterns having the symmetries of any of the 17 wallpaper groups has been uploaded to the Ultra Fractal formula library. They are best used on a "pixel" formula (there are some in sam.ufm), with the "View Trap Shape" outside coloring (in sam.ucl). To see images produced with a close cousin of this algorithm, see this gallery.

...at p-gallery.net. 3245x3245 pixel images of these works are available through OpenZoom.

Slightly higher resolution images available

Each of my work is rendered at 3425x3425 pixels and printed in a photobook for records. These images have been lying around on my computer, so I thought I could as well display them with OpenZoom. Some works on pages 82 to 84 at p-gallery.net can now be explored at this resolution. It's nothing like gigapixel images, but still, they allow to see a bit more.

20080818

Here is a 65536 x 65536 pixel image of 20080818. This work is based on an "Invaders" pattern, piled at various scales.

"Invaders" refers to Space Invaders, one of the first informatic game, released in 1978. This game consisted in shooting from a spacecraft on extraterrestrial "invaders". Because of the poor resolution of the computer screens at this time, the latter were coarsely represented by two color 10 x 10 pixel matrices.

The "Invaders" pattern divides the plane into squares, and further divides these squares into pixels (here each square is divided into 5 x 5 pixels). It attributes randomly to each of these pixel an index value among two possible one. Interestingly, if one forces a vertical mirror symmetry on each of these pixel matrices, and provided the number of pixels is not too big, patterns reminiscent of Space Invaders appear.

This pattern was inspired by complexification.net.

OpenZoom

I switched from Zoomify to OpenZoom. The way it zooms is much smoother, and the full screen mode works with Google Chrome, unlike Zoomify. Have a look here and here. It also allows for complete customization, but I haven't figured this out yet.

About algorithmic worlds...

No new image yet. It's still rendering.

However I have updated a part of the "About..." section. Feel free to comment here if you have remarks or if you spot English mistakes.
