Alors petit programe du jour:
|
|
* On a une liste de point.
|
|
* On l'affiche a l'ecran.
|
|
* on format une chaine de charactere pour l'afficher avec le laser
|
|
*
|
|
* On definie des courbe de bezier
|
|
* On affiche un tunnel
|
|
* Il faudra un truc pour definir
|
|
*
|
|
|
|
* ===
|
|
* Il nous faut une structure de segment [{pos_x, pos_y, color}, {pos_x, pos_y, color}]
|
|
* Un tableau de
