Row of Noise

Hello everyone,

So I have temporarily moved my sphere project aside, noting on how difficult it is and I just haven't gotten anywhere on it really, and am trying to work on a new noise demo with which I am trying to create a row of noise with different colors. I am very close as usual I believe, but it wouldn't hurt to get some extra input. Here is my code for this project..................................................................................................................................................

NoiseMaker myNoiseMaker;
NoiseMaker2 myNoiseMaker2;

void setup(){
myNoiseMaker = new NoiseMaker();
myNoiseMaker2 = new NoiseMaker2();
    size(600,100);

}

void draw(){
myNoiseMaker.display();
myNoiseMaker2.display();

if(mousePressed==true){
    save("noiseTexture.tiff");
}
}
-------------------------------------------------------------------------------------------------------------------------------------------------------------------

Here is my first tab for my NoiseMaker class--------------------------------------------------------------------------------------------------

class NoiseMaker {
float xnoise = 0.0;
float ynoise = 0.0;
float inc = 0.08;

NoiseMaker(){
    xnoise = 0;
        ynoise = ynoise +inc;

}

void display() {
    for (int y =0; y <height; y++) {
      for (int x = 0; x<width; x++) {
        float gray = noise(xnoise, ynoise) *255;
        stroke(gray);
        point(x, y);
        xnoise = xnoise + inc;
        size(100,100);
      }
    }
}



}

The second class I have is basically a copy of the first NoiseMaker class. I figured I would just create more classes because I couldn't seem to figure out how to make more Noise blocks.

Here is the second class-----------------------------------------------------------------------------------------------------------------------------------

class NoiseMaker2 {
float xnoise = 0.0;
float ynoise = 0.0;
float inc = 0.08;

NoiseMaker2(){
    xnoise = 0;
        ynoise = ynoise +inc;

}

void display() {
    for (int y =0; y <height; y++) {
      for (int x = 0; x<width; x++) {
        float YELLOW = noise(xnoise, ynoise) *255;
        stroke(YELLOW);
        point(x, y);
        xnoise = xnoise + inc;
        size(100,100);
        translate(width/2,height/2);
      }
    }
}



}

------------------------------------------------------

Any help would be great thank you.

Help With Spheres and Rotation

Hello all I was wondering if anyone can help me with the following code I have created:

Here is the main tab of the sketch..............................................................................................................

Rotating myRotating; //declaring an object here.

void setup(){

size(700,700,P3D); //size of window with P3D initialized.

background(255,0,0); //color of background.

}

void draw(){

translate(width/2,height/2); //this is moving the point of origin to the center of the screen.

myRotating = new Rotating(); //creating a new object here called myRotating.

myRotating.display(); //function of displaying the myRotating.

myRotating.rotation(); //calling the function rotation.

}

-----------------------------------------------------------------------------------------------------------------------------------

Here is my Rotating class I have created------------------------------------------------------------------------

class Rotating{ //class created. ---------------------------------------------This is the data portion of the class.

color c; //color variable created; calling it "c".

float xpos; //float xpos is created.

float ypos; //float ypos is created.

float xspeed; //float xspeed is created.

Rotating(){ // creating the constructor for the class--------------------------This is the constructor of the class.

c = color(255); // c is assigned the color of white.

xpos = 100; //xpos is assigned the width/2 of my screen window.

ypos = height/2; //ypos is assigned the height/2 of my screen window.

xspeed = 10; // xspeed is assigned the value of 1.

}

void display(){ //the function "display" is created.-------------------------------------------------------functionality of the class begins.

ellipseMode(CENTER); //ellipseMode is created and centered.

fill(c); //the fill of the Sphere I have is called through "c" which is assigned the color of white for now.

sphere(200); //the actual sphere is created.

}

void rotation(){ //this is the other function I have created for the class Rotating. -------------------------------Second function of the functionality of the class begins.

xpos = xpos + xspeed; //xpos is being set equal to xpos plus xspeed. Essentially width/2 = width/2 + 1.

if(xpos>width){ //if statement saying if xpos(701) is greater than width(700) then xpos equals 0. This means that the sphere will be drawn from the top left of the screen.

xpos = 705; //xpos being declared 0.

}

}

}

-----------------------------------------------------------------------------------------------------------------

For ease of reading I have highlighted my code. I was wondering if anyone could help me rotate this sphere? I feel like I am so close I just need so guidance. My code is for a demo on Perlin Noise and I am trying to texture map an image of noise I have created onto the sphere to show how procedural texture mapping works. I just haven't gotten to that part yet because I am trying to get my sphere to rotate first. Thanks everyone.

Hello everyone,

I am having a hard time getting my text to appear from my XML file onto the screen; I have no idea where I went wrong, but I have tried nearly everything to fix this. Here is my code.

--------------------------------------------------------------------------------------------------------------------------------------------

XMLElement xml;//enables xml to be used.

//BrownBlock myBrownBlock;//object 1

//BrownBlock myBrownBlock2;//object 2

void setup() {//initial setup of sketch.

size(screen.width, screen.height);//actual size of the window at school is 1920 by 1200.

background(113, 105, 58);//color of background.

smooth();//antialiasing on.

noStroke();//no stroke will be given.

PFont font;//calling the font function and calling the font "font".

PImage img2;//calling second image.

PImage img;//calling the image function and calling it "img".

PImage img3;//calling third image.

PImage img4;//calling fourth image.

PImage img5;//calling fifth image.

PImage img6;//calling sixth image.

PImage img7;//calling seventh image.

PImage img8;//calling eighth image.





img = loadImage("mmnhLogo.png");//loading my image in.

image(img, 80, 70);//naming the image specifically with the variable name "img" and positioning it.



img2 = loadImage("wolf1.png");//loading image number 2 in.

img3 = loadImage("wolf2.png");//loading in image number 3.

img4 = loadImage("wolf3.png");//loading in image 4.

img5 = loadImage("caribou1.png");//loading in image 5.

img6 = loadImage("caribou2.png");//loading in sixth image.

img7 = loadImage("muskOx1.png");//loading in seventh image.

img8 = loadImage("muskOx2.png");//loading in eighth image.

font = loadFont("FelixTitlingMT-30.vlw");//loading in the font I desire.

textFont(font);//calling in the font I am actually going to be using; "font"

fill(245, 239, 215);//the fill of the text.

text("Midwest Museum of Natural History", 210, 125);//text and their coordinates.

font = loadFont("FelixTitlingMT-80.vlw");//loading a different font into the sketch.

textFont(font);//calling it "font".

text("Ice Age", 210, 240);//more text and coordinates.

image(img2,610,400);//coordinates of the second image.

image(img3,800,400);//coordinates of the third image.

image(img4,990,400);//coordinates of the fourth image.

image(img5,740,560);//coordinates for the fifth image.

image(img6, 890,560);//coordinates for the sixth image.

image(img7,740,200);//coordinates for the seventh image.

image(img8,890,200);//coordinates of the eighth image.



}

void draw() {

xml = new XMLElement (this, "museumHomeText.xml");//xml being called.

int numHomeText = xml.getChildCount();

for (int i = 0; i <numHomeText; i++){

XMLElement kid = xml.getChild(i);

int homeText = kid.getInt("homeText");

String datahomeText = kid.getString("homeText");

String mainhomeText = kid.getContent();

}



}

--------------------------------------------------------------------------------------------------------------

The highlighted area is my problem spot in this situation; here is my XML I am loading from.

------------------------------------------------------------------------------------------------------------------

<?xml version='1.0'?>

<museumText>

<data homeText= "During the last Ice Age, the Sycamore region lay at the edge of a mile thick sheet of ice.

Running along one blue ice ridge, across DeKalb County, thick-skinned and rough-haired Mastodons lumbered through the landscape.

The Ice Age display at the Midwest Museum of Natural History features a diorama depicting a portion of this scene designed to illustrate life and change in the Midwest region beginning 12,000 years ago." />

</museumText>

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

I have been following the XML example on the Processing website and trying to substitute my corresponding values in, but I get stuck when I get to the string part of the code because I don't know what to call my string. Any help would be wonderful thank you.

Hello everyone,

After countless searching of topics posted on this forum I am still in need of some help with my code for an interactive kiosk I am working on. I am using classes for everything on this project; I am trying to load in some .mov files I made in Adobe After Effects CS5 and I cannot get them to work. I will post my code.

---------------------------main tab--------------------------------------------------------------------------informativeKiosk---------------------------

import processing.video.*; //importing the video library.

Movie myMovie; //calling my video Wolf Video.

XMLElement xml; //enables xml to be used.

BrownBlock myBrownBlock; //object 1

BrownBlock myBrownBlock2; //object 2

void setup() { //initial setup of sketch.

size(screen.width, screen.height); //actual size of the window at school is 1920 by 1200.

background(113, 105, 58); //color of background.

smooth(); //antialiasing on.

noStroke(); //no stroke will be given.

//noCursor(); //cursor hidden.

PFont font; //calling the font function and calling the font "font".

PImage img; //calling the image function and calling it "img".

img = loadImage("mmnhLogo.png"); //loading my image in.

image(img, 80, 70); //naming the image specifically with the variable name "img" and positioning it.

font = loadFont("FelixTitlingMT-30.vlw"); //loading in the font I desire.

textFont(font); //calling in the font I am actually going to be using; "font"

fill(245, 239, 215); //the fill of the text.

text("Midwest Museum of Natural History", 210, 125); //text and their coordinates.

font = loadFont("FelixTitlingMT-80.vlw"); //loading a different font into the sketch.

textFont(font); //calling it "font".

text("Ice Age", 210, 240); //more text and coordinates.

//myMovie = new Movie(this, "wolfVid.mov"); //calling a new object here; wolfVid.mp4.

myMovie.loop(); //loops movie for me.

//myBrownBlock = new BrownBlock(color(162,158,117)); //new object being declared.

myBrownBlock2 = new BrownBlock(color(245, 239, 215)); //new object being declared.

}

void draw() { //initiates sketch.

//myBrownBlock.display(mouseX, mouseY); //brown block 1 being controlled with the mouse.

myBrownBlock2.display(900, 500); //brown block 2 being displayed with coordinates.<---------error here!

//myMovie.display(900,500); //displaying my video on the screen of the wolf.

//if(mousePressed==true){

//save("mmnh###.png");

}

-----------------------------------------------second tab----------------------------------------brownBlock class---------------------------------------

class BrownBlock { //BrownBlock class being created.

//int xpos;

//int ypos;

color c; //color variable.

BrownBlock(color tempC){ //temporary variables are initiated.

c = tempC; //c is declared.

//int xpos = width/2;

//int ypos = height/2;

}



void display(int xpos, int ypos){ //function void display is positioned with xpos and ypos.

rectMode(CENTER); //rectangle is drawn from the center.

fill(c); //fill of the rectangle is variable c.

rect(xpos,ypos,600,300); //coordinates of the rectangle.

}

-------------------------------------------------third tab------------------------------------------------movieClass------------- for my first slide show

class Movie{ //class wolf being created.



// Movie(){ //data of class.

// Movie(this, "wolfVid.mp4.mp4"); //actual video of the class being created.

// Movie(this, "wolfVid.mp4.mp4", 15);

// Movie(this, computer,NIU(E:),informativeKiosk,data);

// Movie(this, computer,NIU(E:),informativeKiosk,data,15);

}





void display(int xpos, int ypos){ //functionality of the class.

rect(xpos,ypos,600,300); //coordinates of the video.

}

void loop(){

myMovie.loop();



}

}

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

Basically I am getting better with processing, but I have never worked with video before in this program, and I am unsure whether or not I am going about this correctly? I have a good handle on classes thanks to the OOP search I get on the main website. For some reason the error is saying the "function display(int,int) does not exist. I thought it did because I see the function in the BrownBlock class? I also have the "Processing: A Programming Handbook for Visual Designers and Artists" book which is great! Although there is no mention of video in the book that I could find in the index. Any help would be greatly appreciated thank you.

Safety and Peace,
