parameters of line drawing computer graphics code example
Example: Bresenham's line algorithm
static void bresenham(int x1, int y1, int x2, int y2)
{
int m_new = 2 * (y2 - y1);
int slope_error_new = m_new - (x2 - x1);
for (int x = x1, y = y1; x <= x2; x++)
{
System.out.print("(" +x + "," + y + ")\n");
// Add slope to increment angle formed
slope_error_new += m_new;
// Slope error reached limit, time to
// increment y and update slope error.
if (slope_error_new >= 0)
{
y++;
slope_error_new -= 2 * (x2 - x1);
}
}
}
