j'ai fais une v2
avec un shader pour animer les poissons, ça rend pas mal, pour pas un rond
+ quelques autres améliorations
[ F1 ] pour embarquer la camera sur un gros poisson (ou la libérer)
salut les codeurs,
la version 3D de ma modélisation d'un banc de poisson
pas dégueu !
enlever lee déboggeur
si ça suffit pas compiler avec le Backend C avec optimisation
si ça suffit toujours pas diminuer le nombre de poisson (ligne 5)
