This is my personal approach to implement the Collatz conjecture into a julia fractal .

Code:

	
void yFractal::GetFractalColor66() 
{
	static double	x, y, prev_x, prev_y;
	static int		n, i;

	x=m_StartX;
	y=m_StartY;

	for(n=0; n<m_Iterations; n++)
	{
		prev_x=x;
		prev_y=y;

		x=(prev_x*prev_x) - (prev_y*prev_y) - m_CustomRange4;
		y=(2.0 * prev_x * prev_y)           + m_CustomRange2;

		i=int(prev_x/prev_y);

		if(i%2==0)
		{
			if(m_CustomRange2!=0.0)
			{
				x=x/1.4;
				y=y/1.4;
			}
		}
		else
		{
			x*=m_CustomRange3;
			x+=m_CustomRange1;
			y*=m_CustomRange3;
			y+=m_CustomRange1;
		}

		if( ((x*x)+(y*y)) >= m_Magnitude )
		{
			m_C=int( float(n) * m_ColorPerIteration ); // Return color index from range 0 to (m_NumColors-1)
			return;
		}
	}

	m_C=0;
}

Made with yFract.
