Creating 3D animation with math expressions

Hello @aalgoro,

How to go from plane to 3D

float t=1; void setup() { size(800, 800); } void draw() { background(0); noStroke(); fill(255); translate(width/2, height/2); for (int i = 0; i < 100; i++) { float x = width/4 * sin(t*i*PI*2); float y = height/4 * sin(t*i*PI*3); rect(x,y,2,2); } t += 0.00001; } Hello, I have this system of equations that cause the points to move like on a Lissajous curve. I’m trying to add a third dimension to it and be able to change the point of view of the camera to visu…

Code from above simplified:

void setup() 
  {
  size(800, 800, P3D);
  }

void draw() 
  {
  background(255);
  strokeWeight(5);
  
  translate(width/2, height/2);

  for (int i = 0; i < 300; i++) 
    {
    float x = width/4*sin(i*PI*2/100);
    float y = height/4*sin(i*PI*3/100);
    float z = 200*sin(i*PI*4/100);
    point(x, y, z);
    }
  }

The above site is poorly formatted and this is cleaner:

x = cosine(theta)*radius 
y = sine(theta)*radius

float x = cos(radians(angle))*radius;
float y = sin(radians(angle))*radius;

Have fun!
