A aircraft is moving on a terrain by reading the x-y values from a file.
I wanted to trace the path of the aircraft by drawing the line.
But the problem is the file is very big and has lots of points so i cannot use glBegin(GL_LINE_STRIP) as it draws line starting form the initial point to the final but i cannot keep track of all the points as the coordinates from file are large in number.
I certainly has no idea how to proceed???
