I'm programming a sound equalizer for a university project, see code below.

the code below is a sketch at 1024x640 where everything works fine.

But the final project needs to be 6144x640 and I then get the problem that it puts the start of the equalizer in the middle of the screen, whereas I need it to start on the left side.
When putting a simple offset value I can get it to the left side but it looks totally different due to camera settings/distortion...

What I basically need is the equalizer to look exactly like the one in my 1024px sketch, but on the left side of the 6144px sketch!

can anybody help me with my camera settings, or is there an easier way to achieve the look?
thanks for your help!

here is the code, it reacts to audio input, so plug in a mic and leave some music running...
_____________
import ddf.minim.*;

Minim minim;
AudioInput in;

float randomhue;

void setup () {
 size(1024, 640, P3D);
 background(0);
 colorMode(HSB, 500, 100, 100);


 minim = new Minim(this);  
 minim.debugOn();

 // get a line in from Minim, default bit depth is 16
 in = minim.getLineIn(Minim.MONO, 96);

}

void draw(){
 camera(140.0, 420.0, 120.0, 150.0, 150.0, 0.0, 0.0, 1.0, 0.0);


 background(0);
 /*  if(frameCount % 100 == 0){
  randomhue = random(500);
  }
  stroke(random(randomhue,randomhue-20),50,75, 30); */
 for (int i=1; i < in.mix.level()*500; i = i+1)
 {
   for(int j=0; j < 30; j = j+1){
     for(int k = 0; k < in.bufferSize() - 1; k++)
     {
       stroke(i*in.mix.get(k+1)*100,75,(k+1)*4, 50);
       point(i*10, j*5, in.mix.get(k+1)*400);



     }
   }
 }

}
void stop()
{
 // always close Minim audio classes when you are done with them
 in.close();
 minim.stop();

 super.stop();
}

I would have thought it would be as simple as that too, but maybe it's not.  camera takes arguments that set two points: one is the position of the eye/camera the other is the 'centre of the scene' - i.e. the target the camera is pointing at.  It looks to me like he's made adjustments to camera to get it facing his points, when in fact he might be better off leaving camera alone and looking into how to position the points where he needs them...  My initial hunch was that a translate operation would do the trick...

I'm assuming the final piece is going to be split over several monitors - perhaps an alternative solution might be to render separate windows (assuming that's straightforward - I'm thinking aloud here...)

there must be an easier way to just offset it to not have it start in the center but on the left side of the screen.....I'm very new to processing and quite stuck, plus the project has to be finished by monday....

OK 2 things:

1. From size: "The maximum width and height is limited by your operating system, and is usually the width and height of your actual screen. On some machines it may simply be the number of pixels on your current screen, meaning that a screen that's 800x600 could support size(1600, 300), since it's the same number of pixels. This varies widely so you'll have to try different rendering modes and sizes until you get what you're looking for. If you need something larger, use createGraphics to create a non-visible drawing surface."

So what you're trying may not be possible anyway.  Sorry not to spot this sooner, but I guess we were assuming that you'd verified you could do it.  Assuming you can then:

2.  I'm not going to do your homework for you but here's a hint: comment out your camera line and try changing the order of variables in your point call:

point(i*10, j*5, in.mix.get(k+1)*400);

...remembering that the order of the parameters is x, y and z.  You currently have the minim input on the Z (depth) axis.  You can then add offset values to each to adjust the position.  Having said that it may still not look the way you want because of the effects of perspective, unless you rotate the whole construction to face the camera.  To put it another way: if you fix the camera so this section looks right you'll probably have problems with anything else being rendered...

6144/6 = 1024

Which would suggest a multiple monitor setup set in the OS to be a single extending screen.  The only way I can think to get 6 monitors on a single PC is using DisplayLink.  Assuming that's the case be warned that whilst this technology is very cool it does have its limitations, namely in terms of the speed with which it can process and render output - it's great for day-to-day tasks, but not so good with content dependent on high framerates (e.g. video, games etc...).  Again something to consider before spending too much time trying to get a 6144px wide sketch running the way you want it.
