week 7. 3D primitives and array

size(640, 360, P3D); 
background(0);
lights();

noStroke();
pushMatrix();
translate(130, height/2, 0);
rotateY(1.25);
rotateX(-0.4);
box(100);
popMatrix();

noFill();
stroke(255);
pushMatrix();
translate(500, height*0.35, -200);
sphere(280);
popMatrix();

example2:

int gridSize = 50;
void setup(){
  size(640,360,P3D);
  
  fill(204, 204, 10);
}  
  
  
void draw() {  
  background(0);
  lights();
for (int i = 0+gridSize/2; i< width; i += gridSize)
  for (int j = 0+gridSize/2; j< height; j+= gridSize)
  {
    pushMatrix();
    translate(i, j, 0);
 //   rotateY(frameCount/5);
    rotateX(frameCount/7);
    noStroke();
    box(20);
    popMatrix();
  }
}

Example3, cube rotation + 2D array 

float[][] rotateRates;


int gridSize = 50;
void setup(){
  size(640,360,P3D);
  rotateRates = new float[width][height];
  
  for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++) {
    
      rotateRates[x][y] = random(2.0, 40.0);
    }
  }
  fill(204, 204, 10);
}  
  
  
void draw() {  
  background(0);
  lights();
for (int i = 0+gridSize/2; i< width; i += gridSize)
  for (int j = 0+gridSize/2; j< height; j+= gridSize)
  {
    pushMatrix();
    translate(i, j, 0);
 //   rotateY(frameCount/5);
 //   rotateX(frameCount/7);
    rotateX(frameCount/rotateRates[i][j]);
    noStroke();
    box(20);
    popMatrix();
  }
}

Examples 4:

float[][] rotateRates;


int gridSize = 50;
void setup(){
  size(640,360,P3D);
  rotateRates = new float[width][height];
  
  for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++) {
    
      rotateRates[x][y] = random(5.0, 40.0);
    }
  }
  fill(204, 204, 10);
}  
  
  
void draw() {  
  background(0);
  lights();
for (int i = 0+gridSize/2; i< width; i += gridSize)
  for (int j = 0+gridSize/2; j< height; j+= gridSize)
  {
    pushMatrix();
    translate(i, j, sin(frameCount/20.0)*20.0);
 //   rotateY(frameCount/5);
 //   rotateX(frameCount/7);
    rotateX(frameCount/rotateRates[i][j]);
    noStroke();
    box(20);
    popMatrix();
  }
}

example 5: using sin

float[][] rotateRates;


int gridSize = 50;
void setup(){
  size(640,360,P3D);
  rotateRates = new float[width][height];
  
  for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++) {
    
      rotateRates[x][y] = random(5.0, 40.0);
    }
  }
  fill(204, 204, 10);
}  
  
  
void draw() {  
  background(0);
  lights();
for (int i = 0+gridSize/2; i< width; i += gridSize)
  for (int j = 0+gridSize/2; j< height; j+= gridSize)
  {
    pushMatrix();
    translate(i, j, sin((frameCount/10.0)%width+i)*50.0);
 //   rotateY(frameCount/5);
 //   rotateX(frameCount/7);
    rotateX(frameCount/rotateRates[i][j]);
    noStroke();
    box(20);
    popMatrix();
  }
}
