I wrote a small program that creates the waves in C++. The part for the waves looks like this:

code:

---

void CalculateWaves (void)
{
	WORD x;
	WORD y;
	short tmp_value;
	for (y = 2; y < 198; y++)
	{
		for (x = 2; x < 198; x++)
		{
			tmp_value = ( WaveMap[CT][x-1][y] +
				WaveMap[CT][x-2][y] +
				WaveMap[CT][x+1][y] +
				WaveMap[CT][x+2][y] +
				WaveMap[CT][x][y-1] +
				WaveMap[CT][x][y-2] +
				WaveMap[CT][x][y+1] +
				WaveMap[CT][x][y+2] +
				WaveMap[CT][x-1][y-1] +
				WaveMap[CT][x+1][y-1] +
				WaveMap[CT][x-1][y+1] +
				WaveMap[CT][x+1][y+1]
				) / 6 - WaveMap[NW][x][y];
			tmp_value = tmp_value / 1.1;
			WaveMap [NW][x][y] = tmp_value;
		}
	}
	char old_ct = CT;	// CT und NW vertauschen
	CT = NW;
	NW = old_ct;
}
