hello, i'm trying to make a program with processing, but i need to replace the object of the pg.graphics, with the obj 3D... And more, with a 3D that i can choose with the SelectInput().

But i modify all this code, who come from an other person, and i don't know how i can change, box() and everything, in a good obj viewer...

>.<

Would you help me just a little bit, that's can be great thank youuuuuuuuu!

the code (i think i make some mistake...):
