Más arbolicos...
Estoy un poco liado preparando un tutorial sobre los sistemas de Lindenmayer. Tendréis más noticias cuando esté listo. De momento, ahí va una imagen de muestra de la pinta que tiene lo que hace a día de hoy...
Un saludo a todos!

Otra cosa, ahora ya se pueden recibir feeds de este blog. Los enlaces son los siguientes:
También he puesto estos enlaces en la barra lateral.

El código...
Tened en cuenta que todavía no está terminado... Pero aún así posteo el código... :)
Rule.cs:
TreeParams.cs:
LSystem.cs:
Renderer.cs:
CommandParser.cs:
frmTreeParams.cs:
frmRender.cs: (contiene el método Main)
Y ya está... De momento eso es todo... ;)
Cuando tenga listo el pintado del árbol, postearé el código completo (si puedo, en un zip, en vez de poner el código...)
