How would I modify this code to change the output of the code

How would I modify this code to change the output of the code so that the flat grid looks like a U instead of flat. Basically how to do I move up the corner positions of the grid? Thank you for your help

  • </> code is below:

import processing.serial.;
import processing.opengl.;

int bgcolor; // Background color
int fgcolor; // Fill color
Serial myPort; // The serial port
int[] serialInArray = new int[225]; // Where we’ll put what we receive
int[] pastInArray = new int [225];
float[][] colorTarget = new float[3][255];
float[][] currentColor = new float[3][255];
PVector[][] vertices = new PVector[15][15];
float[] verticesTZ = new float[15];
float w = 30;
float ease = 0.75;

int serialCount = 0; // A count of how many bytes we receive
int xpos, ypos; // Starting position of the ball
boolean firstContact = false; // Whether we’ve heard from the microcontroller
int tiempoant;
int render=0;
int dif=0;

void setup() {
size(960, 600, OPENGL); // Stage size
noStroke(); // No border on the next thing draw

// Print a list of the serial ports, for debugging purposes:
println(Serial.list());

// I know that the first port in the serial list on my mac
// is always my FTDI adaptor, so I open Serial.list()[0].
// On Windows machines, this generally opens COM1.
// Open whatever port is the one you’re using.

myPort = new Serial(this, Serial.list()[4], 115200);

for (int j = 0; j < 15; j++) {
for (int i = 0; i < 15; i++) {
vertices[i][j] = new PVector( iw, jw, 0);
}
}

}

void draw() {

if (render==1) {

translate(width/4, 100);
rotateX(0.5);
//rotateX(PI/10);
background(0);
for (int j=0; j<14; j++) {
  beginShape(QUAD_STRIP);
  for (int i=0; i<15; i++) {
      stroke(255);
 
      fill(serialInArray[j*15+i], 0, 0);
      float x = i*width/15;
      float y = j*height/15;
      verticesTZ[i] = serialInArray[j*15+i];
      
      vertices[i][j].z += (verticesTZ[i]-vertices[i][j].z)*ease;
      vertex( vertices[i][j].x, vertices[i][j].y, vertices[i][j].z);
      vertex( vertices[i][j+1].x, vertices[i][j+1].y, vertices[i][j+1].z);
    }
     endShape(CLOSE);
    //        println();
  }
  render=0;

}
}

void serialEvent(Serial myPort) {
// read a byte from the serial port:
int inByte = myPort.read();
// if this is the first byte received, and it’s an A,
// clear the serial buffer and note that you’ve
// h
// ad first contact from the microcontroller.
// Otherwise, add the incoming byte to the array:
if (firstContact == false) {
if (inByte == ‘A’) {
myPort.clear(); // clear the serial port buffer
firstContact = true; // you’ve had first contact from the microcontroller
myPort.write(‘A’); // ask for more
}
} else {
// Add the latest byte from the serial port to array:

  serialInArray[serialCount] = inByte;

serialCount++;

// If we have 3 bytes:
if (serialCount >= 225 ) {
  println(millis()-tiempoant);
  tiempoant = millis();
  
  render = 1;

  // Send a capital A to request new sensor readings:
  myPort.write('A');
  // Reset serialCount:
  serialCount = 0;
}

}
}
