How would you do it?

you are talking about a ZOOM ALL or FIT TO WINDOW function , right?

i've never donne it before, but if a better idea doesn't show up i can think about 2 solutions,

scaling all vars (measures) according to the size of the window , on the fly. VERY BAD.

or, with some math function,
calculate the far edges of the drawing,
and using the EYE VIEW angle of the camera,
calculate how much the camera as to move back or forward in order to make de drawing fit the window.

i don't mess around with 3D in processing in 2 years, a lot of things changed,
maybe this aproach is outdated.....

I did not find any eye view. How would you do this using p3d or opengl? Are you talking about translate?

when i said eye view , i meant the angle of the camera, not a function.
somehow you have to find that angle in the documentation.

as people use to say, a picture is worth a thousand words, i hope i'm better drawer than english speaker,
good luck roger.

Yes, http://processing.org/reference/perspective_.html is the way to go. But I need to know how to move the camera...

see this camera page ,
eyeX, eyeY, eyeZ is the position of the camera, you can play along with those values to move it around.

centerX... is the target point of the camera.

i'm not really sure if perspective is what you are looking for.

but that fov value may be what you need.

i can think about 2 possibilities,

a) find the default value of fov,
b) set your own fov

and then calculate the needed distance of the camera.

Yes that worked.
