pez en 3D
Publicado por Paco Martinez (1 intervención) el 26/05/2011 20:05:36
Hola a todos, necesito a partir de un pez hecho en 2D con transformaciones geométricas, con su zoom, movimientos de translación..etc.. a partir de eso hacerlo en 3D... y no se como hacerlo ni que funciones utilizar... alguien me puede echar una mano????? Gracias..
Os dejo el codigo:
