Can someone tell me an elegant way to draw a waveform with sin() but with curveVertex? I use the following with ellipse, but I want to change it, however I can't find enough info and all my experiments failed.

Thanks!

2. // Starting angle
3. float theta = 0.0;
4. 
   
5. void setup() {
6.   size(500, 300);
7.   smooth();
8. }
9. 
   
10. void draw() {
11.   background(255);
12. 
    
13.   // Increment theta (try different values for " angular velocity " here)
14.   theta += 0.02;
15.   noStroke();
16.   //stroke(1);
17.   fill(0);
18.   //noFill();
19.   float x = theta;
20.     
21.   // A for loop is used to draw all the points along a sine wave (scaled to the pixel dimension of the window).
22.   for (int i = 0; i <= width; i++) {
23.     float y = sin(x) * height/4;
24.     
25.     beginShape();
26.     
27.     ellipse(i*10, y + height/2+(1*10), 5, 5);
28.     ellipse(i*10, y + height/2+(2*10), 5, 5);
29.     ellipse(i*10, y + height/2+(3*10), 5, 5);
30.     
31.     x += 0.2;
32.     endShape();
33.   }
34. }
