Mandlebrot task class
0
I'm trying to implement mandelbrot however it my main classes it draws a single color because all of the iteration counts are staying at zero. I've looked for the cause of this for a while and couldn't determine what is causing it to do this. I looked for other sources however their approach was completely different. All of the drawing is done in the main class and the magnitude add and multiply methods were created in a third class.
package edu.ycp.cs201.mandelbrot;
public class MandelbrotTask implements Runnable {
private double x1, y1, x2, y2;
private int startCol, endCol, startRow, endRow;
private int iterCounts;
public MandelbrotTask(double x1, double y1, double x2, double y2,
int startCol, int endCol, int startRow, int endRow,
int iterCounts) {
this.x1 = x1;
this.y1 = y1;
this.x2 = x2;
this.y2 = y2;
this.startCol = startCol;
this.endCol = endCol;
this.startRow = startRow;
this.endRow = endRow;
this.iterCounts = iterCounts;
}
public void run() {
for (int i = startRow; i < endRow; i++) {
for (int j = startCol; j < endCol; j++) {
Complex c = getComplex(i, j);
int iterCount = computeIterCount(c);
iterCounts[i][j] = iterCount;
}
}
}
// TODO: implement getComplex and computeIterCount methods
public Complex getComplex(int x, int y) {
//return new Complex (x, y);
double col = (double) endCol - (double) startCol;
double row = (double) endRow - (double) startRow;
double dx = x2 - x1;
double dy = y2 - y1;
return new Complex(x1 + dx / col * x, y1 + dy / row * y);
}
public int computeIterCount(Complex complex) {
//Zo is initially 0+0i
Complex z = new Complex(0,0);
//# of iterations
int count = 0;
//while z has magnitude of less than 2 and iteration counts have not
exceeded MAX
for (int k = 0; k < 100; k++) {
//iterate complex number
z = z.multiply(z).add(complex);
//if magnitude of complex number is >2 stop
if (z.getMagnitude() > 2) {
break;
}
//increment count
count++;
}
return count;
}
}

Did you copy and paste this code directly from source? The code as provided wouldn't compile due an exposed comment in thecomputeIterCountfunction, right above the for loop.

Are you sure you’re calling therun()method of MandlebrotTask?
