im having a lot of trouble trying to get my 3D etch a sketch background to rotate to allow the user of my etch a stech to see their 3D image clearly and i am wandering how it can be achieved :

here is my code so far:

import processing.opengl.*;

int x, y, z;

int speed = 10;

float a;

float b;

PImage etch;

color bgColor;//global declaration for random backgrounds

void setup() {

size(700, 630, OPENGL);

etch = loadImage("etchaskechcha.jpg");

background(etch);

a = (random(128));

}

void draw() {

if (key == 's'){

//off button

background(0);

// Button turns off

smooth();

strokeWeight(4);

fill(200);

ellipse(width/2, height/2, width/3+25, height/3+25); // gray edge

fill(134, 0, 0);

ellipse(width/2, height/2, width/3, height/3); // red button

strokeWeight(2);

stroke(0);

ellipse(width/2, height/2, width/6, height/6); // black color

line(width/2, height/2-20, width/2, height/2-75);

}



else if(key == 'e'){

exit();

}



lights();// shadow

pushMatrix();

translate(width/2, height/2);

noFill();

//b = stroke(128, 128);

//stroke(a);

box(350, 270, 407);//the contruct of 3D environment (w,h,d)

//beginShape();

//vertex(35, 50,407);

//vertex(65, 50);

//vertex(35, 80);

//endShape();

translate(width/12, height/12);

translate(x, y, z);

noStroke();

strokeWeight(20);//weght of sketch

//stroke(128);//sketch is grey



fill(a);//colour of sketch

box(10);//sketch

smooth();

//strokeWeight(200);

//stroke(50);

//noFill();

//smooth();

strokeWeight(1.4);//border thickness

popMatrix();



if (mousePressed) {

int bg = int(random(5));



if (bg==0) {

background(0, 0, 255);//when screen yellow marker turns blue

tint(255,128);

}

else if (bg== 1) {

background(0, 0, 0);// black

tint(255,128);

}

else if (bg== 2) {

background(51, 255, 51);//green

tint(255,128);

}

else if (bg== 3) {

background(255, 255, 0);//yellow

tint(255,128);

}

else if (bg== 4) {

background(255, 69, 0);//red/orange

tint(255,128);

}

background(etch);

}

}

void keyPressed() {

if (keyCode == UP) {

y-=speed;

}

if (keyCode == DOWN) {

y+=speed;

}

if (keyCode == LEFT) {

x-=speed;

}

if (keyCode == RIGHT) {

x+=speed;

}

if (keyCode == SHIFT) {

z+=speed;

}

if (keyCode == CONTROL) {

z-=speed;

}

}

thank you for your time

please help i am having trouble allowing the sphere to draw a line. and i have read the basics and im still stuck

import processing.opengl.*;

int x, y, z;

int speed = 10;

//PImage etch;

void setup() {

size(700, 630, OPENGL);

}

void draw() {

background(255, 255, 255);

lights();

pushMatrix();

translate(width/2,height/2);

box(450);{ noFill();}

box(450);{ noFill();}

translate(width/12,height/12);

translate(x, y, z);

strokeWeight(2);

stroke(5);

sphere(5);

strokeWeight(2);

stroke(5);

noFill();

smooth();

strokeWeight(10.0);

strokeJoin(MITER);

beginShape();

vertex(35, 20);

vertex(65, 50);

vertex(35, 80);

//endShape();

popMatrix();

}

void keyPressed() {

if (keyCode == UP) { y-=speed; }

if (keyCode == DOWN) { y+=speed; }

if (keyCode == LEFT) { x-=speed; }

if (keyCode == RIGHT) { x+=speed; }

if (keyCode == SHIFT) { z+=speed; }

if (keyCode == CONTROL) { z-=speed; }

}

i was wondering how i can make the sphere movee backwards and forwards , left and right and up and down.

thecode:

//import processing.opengl.*;// BY IMPORTING THE GRAQPHIC CARD IS ENABLED.

float inc = 6;

boolean LEFT ;

boolean RIGHT;

boolean UP;

boolean DOWN;

void setup () {

noFill();

size(600, 600, OPENGL);// OPENGL ALLOWS THE USER TO ACCES THE GRAPHICS CARD.

frameRate(12);

noLoop();

}

void draw() {

background(123, 0, 5);

//lights();// adds a flourescent light and shadows kabanga

inc = 0.5 ;

pushMatrix();

translate(width/2,height/2);// allows the image to be at the centre of the page//by adding mouse function i will be allowed to move the sqaure

//rotateX(mouseX); //this will rotate the x axis

//rotateY(mouseY);//this will rotate the y axis

//rotateZ(inc);

//allows the object to rotate groovy alothough a z rotate is not needed.

box(400,400,400);

box(inc++);

smooth();

popMatrix();

}

im currently doing a challenge at my uni which involves creating a 3D etch a Sketch . my group has managed to do a 2D version but cant get around doing it in 3D plz help.

2D Version code :

int xpos = 150;

int ypos = 150;

int rectWidth;

boolean left;

boolean right;

boolean up;

boolean down;

color bgColor;//global declaration for random backgrounds

PImage etch;//loads image of the frame of etch a sketch

void setup() {

size(700, 630,P3D);

frameRate(50);

etch = loadImage("etchaskech.jpg");

fill(51, 255, 51);// the sketch colour

smooth();

//background(128);//grey background

noStroke();

rectWidth = width/2;

background(etch);// frame

}

void draw() {

if (keyPressed) {

if (key == 's'){

//off button

background(0);

// Button turns off

smooth();

strokeWeight(4);

fill(200);

ellipse(width/2, height/2, width/3+25, height/3+25); // gray edge

fill(134, 45, 0);

ellipse(width/2, height/2, width/3, height/3); // red button

strokeWeight(2);

stroke(0);

ellipse(width/2, height/2, width/6, height/6); // black color

line(width/2, height/2-20, width/2, height/2-75);

}



else if(key == 'e'){

exit();

}

}

}

//background(etch);

//this changes the background colours to the 5 random colours assigned with integers

//changes the colour of the marker

//clears the screen

if (mousePressed) {

int bg = int(random(5));

if (bg == 0) {

bgColor = color (255, 255, 0); //yellow

}

else if (bg == 1) {
