Help processing GIF

[polllynarium]

Hi! It does not work to saddle the gif, the balls disappear because it is not necessary, and the radius does not decrease, I attach the code, please see what is wrong!

}Preformatted text
float angle;
float w = 36;
float ma;
float maxD;
float ang=0;
float angV=0.1;
void setup() {
size(600, 600, P3D);
frameRate(60);
ellipseMode(CENTER);

ma = atan(1 / sqrt(4));
maxD = dist(0, 0, width / 2, height / 2);
}

void draw() {
background(255);
translate(width/2, height/2-150,+70);
lights();

rotateX(-QUARTER_PI-PI/2);
// rotateY(ma);
rotateY(0);
for (int z = 0; z < height; z += w) {
for (int x = 0; x < width; x += w) {
pushMatrix();

  float d = dist(x, z, width / 2, height / 2);
  float offset = map(d, 5, maxD, -PI,PI);
  float a = angle + offset;
  float h = map(sin(a), -1, 1, 50, 150);
  translate(x - width / 2, h, z - height / 2);

  fill(0);
  // noStroke();
  sphere(10);
  popMatrix();
}
angle+=0.01;

}
noStroke();
fill(255);
float r=map(sin(ang),-1,1,0,600);
rotateX(-PI/4);
ellipse(0,950,r2,r2);
ang+=angV;
angV+=0.00001;
}

Hi @polllynarium,

Welcome to the forum!

Can you please format correctly your code by using the </> button:

I also have an error at this line:

ellipse(0, 950, r2, r2);

(the variable r2 is not defined)

[Chrisir]

this works.

maybe the ellipse at the end was covering the spheres?

also, it could be some kind of clipping on the camera

float angle;
float w = 36;
float ma;
float maxD;
float ang=0;
float angV=0.1;

void setup() {
  size(600, 600, P3D);
  //frameRate(60);
  //ellipseMode(CENTER);

  ma = atan(1 / sqrt(4));
  maxD = dist(0, 0, width / 2, height / 2);
}

void draw() {
  background(255);
  translate(width/2, height, -70);
  lights();

  rotateX(-QUARTER_PI-PI/2);
  // rotateY(ma);
  rotateY(0);
  for (int z = 0; z < height; z += w) {
    for (int x = 0; x < width; x += w) {
      pushMatrix();

      float d = dist(x, z, width / 2, height / 2);
      float offset = map(d, 5, maxD, -PI, PI);
      float a = angle + offset;
      float h = map(sin(a), -1, 1, 50, 150);
      translate(x - width / 2, h, z - height / 2);

      fill(222, 0, 0);
      // 
      noStroke();
      sphere(10);
      popMatrix();
    }
    angle+=0.01;
  }

  noStroke();
  fill(255);
  float r=map(sin(ang), -1, 1, 0, 600);
  rotateX(-PI/4);
  // float r2=22; 
  //  ellipse(0, 950, r2, r2);
  //  ellipse(10, 10, r2, r2);

  ang+=angV;
  angV+=0.00001;
}

@polllynarium,

Please format your code:
https://discourse.processing.org/faq#format-your-code

I guessed that r2 should be r*2… that is what happens when you post code that is not properly formatted.

Once I corrected that it seemed to work and I created this:

I did have to make changes to this to center it and I moved the z-axis in the negative direction:

translate(width/2, height/2-150,+70); // I made changes to this

I used saveFrame() and MovieMaker to make the GIF.

The co-ordinate system for P3D is detailed here:

P3D
