How to put the first code in the second code?

    int n = 256;
    int minRad = 50; //minimum radius
    int maxRad = 600;//maximum radius
    float nfAng = 0.01; // angle
    float nfTime = 0.005;//at every 0.005 the shape is being developed
    int outnum;



    void setup() {
       fullScreen();

      pixelDensity(displayDensity());
      background (255);// bg color
      noFill();
      stroke(0, 15);
    }

    void draw() {

        background(255);
         } else {
        translate(width/2, height/2); //Specifies an amount to displace objects within the canvas
      beginShape(); //function that begins recording vertices for a shape
      for (int i=0; i<n; i++) {
        float ang = map(i, 0, n, 0,TWO_PI); //the map() is converting the value in i which ranges from 0 to n into a number from 0 to TWO_PI(a mathematical constant)
        float rad = map(noise(i*nfAng, frameCount*nfTime), 0, 1, minRad, maxRad);
       // the radius using noise() to generate a 'random' number between minRad and maxRad so the resulting circle won't be round but will be wiggly.
        float x = rad * cos(ang);// printing on screen
        float y = rad * sin(ang);//printing on screen
        curveVertex(x, y);// Specifies vertex coordinates for curves.


      } 
      }
      endShape(CLOSE);// funtion that stops recording verticles for a shape
    }

they are the same.

please elaborate

Okay, looks like you have updated the second code.

However, your first code is broken. You have an extra } else { line and an extra bracket } -- at least, I'm guessing that is the problem.

Re:

Please describe exactly what you are trying to do.

You have a "wobbly outline" sketch, and a "video" sketch.

Are you trying to mask the video inside the wobbly outline?

i would like to compine the shape code in the camera code.The camera code include a rect and ellipse. i would like to replace the shape code with these shapes, and the camera captures the motion and the shape will develop.
