And now a lily of the valley. That little series is growing up at good pace !

Three computer generated line art drawings of sakura, wisteria and lily of the valley flowers. Each one made following the straightedge and compass rule, aka Euclidean constructive geometry. The flowers are drawn with black lines, while the underlying constructive straight lines and circles are also shown in light gray. Each flower is framed with a simulation of venetian paper, also procedurally generated.

Following my cherry flower, made using Euclidian constructive geometry, I've now made a wisteria flower.

Algorithmic doodle of the weekend.
I've made a little tool to code Euclide constructive geometry. It processes a description of the geometry as a text file and plot the result. To test it, I've designed this cherry tree flower in the style of Japanese kamon. Made of 240 points, 155 segments, 155 circles, but the script is only 100 lines thanks to a subroutine system.

La première édition française des Éléments d'Euclide est parue en 1632, traduite et commentée par un certain Didier Henrion. La Bibliothèque nationale de France en a un exemplaire.
En plus du caractère unique de ce livre, il y a deux choses très touchantes sur cette page :
- Les mentions « imprimé de son vivant » (Henrion), mais vendu « par la veuve dudit Henrion » ;
- Et cette note manuscrite : « ma bonne maman me la (sic) donné 1632 ».
