How to rotate a box with changing angular velocity

Hi, I am trying to rotate a box with the angular velocity set in array. The data is

(Time)   (X-axis)         (Y-axis)      (Z-axis)
0        -0.00478796     -0.017262705  -0.002968556
1.7      -0.006942641    -0.020502579  -0.004041603
...

Now, the box is rotating with the data in the first row, but I want to add each data like this.

step1 X += -0.00478796
step2 X += -0.006942641
...

Could you give me an advice? And thank you!

int tsvWidth = 0;
int LENGTH;
String [][] tsv;
float t, rotX, rotY, rotZ, X, Y, Z;

void setup() {
  size(800, 800, P3D);
  frameRate(20);
  smooth();

  String lines [] = loadStrings("Satelite_time_Axis_1_Axis_2_Axis_3.txt");

  //calculate max width of tsv file
  for (int i=0; i < lines.length; i++) {
    String [] chars  =  split(lines[i], TAB); //split by TAB, not comma
    if (chars.length > tsvWidth) {
      tsvWidth = chars.length;
    }
  }

  //create tsv array based on # of rows and columns in csv file
  tsv    = new String [lines.length][tsvWidth];
  LENGTH = lines.length; 
  println(LENGTH);
  //parse values into 2d array
  for (int i = 0; i < lines.length; i++) {
    String [] temp = new String [lines.length];
    temp = split(lines[i], TAB);
    for (int j = 0; j < temp.length; j++) {
      tsv[i][j] = temp[j];
    }
  }
}


void draw() {
  background(0);
  println(X, Y, Z);
  renderBox();
  X += Float.parseFloat(tsv[0][1]);
  Y += Float.parseFloat(tsv[0][2]);
  Z += Float.parseFloat(tsv[0][3]);
}

void renderBox() {
  pushMatrix();
  translate(width/2, height/2, 0.0);
  rotateX(X); 
  rotateY(Y); 
  rotateZ(Z);
  fill(128);
  box(400);
  popMatrix();
}
