ho il sospetto (ma non prove certe ) che la colpa sia di beamer

ho trovato anche questa documentazione che mi sembra interessante
http://math.et.info.free.fr/TikZ/bdd/TikZ-Impatient.pdf
ciao
claudio
::
la conoscevo
solo che non mi va di rimparare tutto 🙂
mi accontento di molto di meno
in
http://www.guit.sssup.it/downloads/TikZxGuit2.pdf
si parla per esempio di $((a)!(b)!(c))$
dove si trova la documentazione per questa macro?

::
rispolvero questo post
non esiste una documentazione orientata alla costruzione geometrica più approfondita di http://www.guit.sssup.it/downloads/TikZxGuit2.pdf

Grazie per la risposta

per un’animazione semplice così si tratta di ripetere poche righe di codice ma se la scena è più complessa come si fa?in pratica bisognerebbe definire un nuovo comando che ridisegni la scena di base
