"Present" (full-screen mode) stretched across Multiple Screens

in Contributed Library Questions • 1 year ago

Anyone Know how this should be done....?????\\\

this is my code

import SimpleOpenNI.*;

import processing.opengl.*;

import saito.objloader.*;

SimpleOpenNI kinect;

//---FullScreen fs;

//declare object called model

OBJModel model;

float rotX;

float rotY;

float rotZ;

void setup()

{

size(1200, 1200, OPENGL);

smooth();

// Create the fullscreen object

//--- fs = new FullScreen(this);

// enter fullscreen mode

//--- fs.enter();

frameRate(30);//change

model = new OBJModel(this, "thing_again_blender1_toMeshlab.obj", "relative", TRIANGLES);

model.load("thing_again_blender1_toMeshLab.obj");

stroke(255);

model.enableDebug();

model.scale(300);

model.translateToCenter();//change

noStroke();

kinect = new SimpleOpenNI(this);

kinect.enableDepth();

kinect.enableUser(SimpleOpenNI.SKEL_PROFILE_NONE);

}

void draw()

{

background(0);

lights();

//model.draw

kinect.update();

IntVector userList = new IntVector();

kinect.getUsers(userList);

for (int i=0; i<userList.size(); i++) {

int userId = userList.get(i);

PVector userposition = new PVector();

kinect.getCoM(userId, userposition);

PVector modelrotation = new PVector(userposition.x,userposition.y,userposition.z);

//float angle = acos(modelrotation.dot(userposition));

//PVector axis = modelrotation.cross(userposition); ---> for a neat glitch, turn on!

pushMatrix();

translate(screen.width/2, screen.height/2, 0);

rotateX(radians(rotX));

rotateY(radians(modelrotation.y));

rotateZ(radians(rotZ));

model.draw();

popMatrix();

}

What is your problem exactly ?

Like Jessie is asking, it's best to be a bit more descriptive of your goals and what is not currently working to get better help on the forums. It sounds like you are finding that a full screen app only will fill one screen and you would like to fill multiple screens with your sketch. Is that correct? My solution for multi-fullscreen is to create a chromeless window at a specific location. Before setup add this:

public void init() {
frame.removeNotify();
frame.setUndecorated(true);
frame.addNotify();
super.init();
}

This will create a chromeless sketch window (or application once exported)

then after setting your window size appropriate for the number of screens you are using, add this line to place your window in the correct location:

frame.setLocation(0, 0);

which puts the window at 0,0. you may have to play around with these numbers a bit. on a mac, the 0, 0 point is usually the left corner with the apple, on a windows computer if you right click and arrange your displays, when you click and hold on one of the display icons, the coordinates of its placement should show up in the top left corner of the icon.

This works great for testing and carries over to the exported application too!

good luck!

You have to put the line:

frame.setLocation(0, 0);

inside of draw(), or else it doesn't work.
My first frame of draw() normally looks like this:

if(frameCount == 1) frame.setLocation(0, 0);

I usually put the setLocation() right after size() in the setup(), which seems to get the job done.

Saem here. I've never put it in draw()

Really? I've always had to put it in draw()... I just tested it with the following program, am I doing something wrong (Processing 2.0a7)?

void setup() {
size(displayWidth, displayHeight);
frame.setLocation(0, 0); //This doesn't work
}
public void init() {
frame.removeNotify();
frame.setUndecorated(true);
frame.addNotify();
super.init();
}
void draw() {
if(frameCount == 1) frame.setLocation(0, 0); //This does
println(millis());
}

Perhaps it's a difference between operating systems... I'm using Windows 7 64 bit...

Hmm, maybe its a 2b7 thing, I've been sticking with 1.5.1 until all the libs I use are supported.

Im not sure if it makes a difference, but I usually put the init before setup:

public void init() {
frame.removeNotify();
frame.setUndecorated(true);
frame.addNotify();
super.init();
}
void setup() {
size(displayWidth, displayHeight);
frame.setLocation(0, 0); //works for me here
}
void draw() {
println(millis());
}

that may be the difference, the init is needed to capture the frame variable, then you can set it's location.

I dunno :)

I normally use 1.5.1, but I just happened to have 2.0a7 open at the moment... it still fails to work for me.
Again, what operating system are you using? I think that might be the difference...

I'm stumped. I might create a discussion topic about this (this thread is deviating quite a bit from the original purpose) later, when I have more time...

For the record, I've created a discussion at Full Screen Approach with the hope of not furthering to litter juliac4's post. akiersky and Jesse Scott, I'd like to try and find out what's going on. Thank you for your time so far...

Re: "Present" (full-screen mode) stretched across Multiple Screens

Hi,

so for clarification, I am not needing full-screen mode really, what i am trying to do is display one window across 3 displays, kind of like a panoramic view, or what the "triple head to go" adapter allows you to do. I can get full-screen easily and I can get multiple monitors hooked up, but each display shows the same image. How can I tell processing/the computer to treat the 3 displays as one entirety/canvas?

What i am trying to do ultimately is have 3 monitors with 3 different 3D object's (.obj files) loaded onto them, however each .obj is reading the SAME data from the kinect which doesn't have memory space to handle 3 open processing sketchs., and therefor needs to be connected from the same processing sketch. I have understood that this is more possible in java than processing, but i am not yet too familiar with java. Or that i could create a class some how, and so far i ahve been able to load multiple files/objects but not display them on their own separate monitor. There is also a library for multiple windows opening from the same sketch in processing but even if I use multiple windows the displays still act as one. This could be a graphics/monitor/hardware issue, but i was trying to think of ways to work around that using code, which i am probably not advanced enough to understand yet...

thanks for your help and if you have any suggestions i am an open ear!!!!

Basically, you can do one of two things:

1) One Large Frame

- Create a canvas sized to the width/height of all three screens (eg. 3840 x 720)

- Create three separate PGraphics buffers of the same size as one screen (eg 1280x720)

- Position them at 0, 0 / 1280, 0 / 2560, 0 respectively

- Draw into them as needed...

2) Three Small Frames

- Declare a secondApplet/thirdApplet and two new PFrame's globally at the start of your sketch

- Assuming you have just two screens:

// GLOBAL VARS
//-----------------------------------------------------------------------------------------
secondApplet s;
PFrame f;
PGraphics two;
// SETUP
//-----------------------------------------------------------------------------------------
...
frame.setLocation(0,0); // This is what Calsign apparently has problems with...
f = new PFrame();
...
//-----------------------------------------------------------------------------------------
// FRAME
public class PFrame extends Frame {
public PFrame() {
setBounds(0, 0, 1280, 720);
s = new secondApplet();
add(s);
removeNotify();
setUndecorated(false);
setResizable(false);
addNotify();
setLocation(720, 0);
s.init();
//show();
setVisible(true);
}
}
//-----------------------------------------
// INIT
public void init() {
frame.removeNotify();
frame.setUndecorated(false);
frame.setResizable(false);
frame.addNotify();
super.init();
}
//-----------------------------------------
// 2ND SCREEN
public class secondApplet extends PApplet {
public void setup() {
size(1280, 720);
// etc.
}
synchronized public void draw() {
if(two != null) {
// Copy
two.beginDraw();
// Draw Your PGraphics Buffer with your second .OBJ
two.endDraw();
image(two, 0, 0);
}
}
}
//-----------------------------------------------------------------------------------------

That's at least how I've always done it...

Elaborate as necessary for a third screen/applet...

Notes:

- Don't bother with the FullScreen library, IMHO.

- If you are using OPENGL already, it might give you problems. You might be better off looking at the GLGraphics library, and it's OffScreen Textures/Windows...
