Ce projet est la quatri\u00e8me \u00e9volution du protocole Variaciones circa triangula, ce protocole donne lieu \u00e0 diff\u00e9rentes s\u00e9ries qui utilisent toutes le m\u00eame \u00e9l\u00e9ment graphique, le triangle. Comme les autres s\u00e9ries de ce corpus de pi\u00e8ces, ce projet g\u00e9n\u00e9ratif repose sur un \u00e9l\u00e9ment central, la grille modulaire, une grille dont les cellules n\u2019ont pas toutes les m\u00eames hauteurs et les m\u00eames largeurs.<\/p>\n\n\n\n

\u00c0 l\u2019aide de cette grille, et au sein de chaque cellule, le programme va tracer une succession de triangles en faisant varier leurs hauteurs ou leurs largeurs. Cette composition, faite de triangles remplis de noir sur fond blanc, va \u00eatre captur\u00e9e pour \u00eatre ensuite interpr\u00e9t\u00e9 lors de la suite de l\u2019ex\u00e9cution du programme.<\/p>\n\n\n\n

Pour remplir les formes g\u00e9n\u00e9r\u00e9es pr\u00e9c\u00e9demment, le programme va placer des points \u00e0 \u00e9quidistance les uns des autres. \u00c0 l\u2019aide d\u2019un algorithme appel\u00e9, marcheur al\u00e9atoire, ces points vont pouvoir se d\u00e9placer \u00e0 la mani\u00e8re d\u2019une dame sur un plateau d’\u00e9checs. Pour tous ces points, une distance de d\u00e9placement maximum est d\u00e9cid\u00e9e et \u00e0 chaque d\u00e9placement un axe est choisi. Ici, le damier est remplac\u00e9 par la composition g\u00e9n\u00e9r\u00e9e pr\u00e9c\u00e9demment, les points peuvent se d\u00e9placer uniquement sur les cases sombres, les endroits o\u00f9 des triangles ont \u00e9t\u00e9 pr\u00e9alablement trac\u00e9s. Si dans l’intervalle entre son point d\u2019origine et son point d\u2019arriver, il rencontre une surface intacte, sa progression s\u2019arr\u00eate et il pourra r\u00e9essayer de se d\u00e9placer sur un autre axe un certain nombre de fois avant de s\u2019arr\u00eater d\u00e9finitivement.<\/p>\n\n\n\n

Bien que le programme ne recourt pas \u00e0 l\u2019intelligence artificielle pour \u00e9laborer les trac\u00e9s, le degr\u00e9 d\u2019autonomie du programme et le fait qu\u2019il interpr\u00e8te lui-m\u00eame le r\u00e9sultat d\u2019un premier calcul donne \u00e0 ce projet une dimension auto r\u00e9flexive. Cette mise en \u0153uvre en deux temps, avec deux processus distincts conf\u00e8re au programme une capacit\u00e9 \u00e0 analyser et r\u00e9intervenir sur son propre travail.<\/p>\n\n\n\n
