focal length

when drawing in 3d,
is there a way to fix the focal length
(in order to change the field of vision) ?
i haven't found any way to do that, so
would anyone get me up to date ?
thanks.

there is the perspective() statement (has to be enclosed between beginCamera() and endCamera() statements), like in:
perspective(30.0f, (float) width / (float) height, 1.0f, 1000.0f)
the first param is for the Field Of View (by default, processing is using 60.0f...)
an (old) interactive example with source code can be found here:
