I saw a world map closely with lines all across it and wondered how to implement world map with latitudes and longitudes using computer graphics. As I very weak in geography can you please help? Reply ASAP.
A world may be simple or it may be pretty complicated. A complicated world map consists of world map with latitudes and longitudes. The latitudes and longitudes define particular places degrees at which the place lies which can be drawn using GL_POLYGON taking two latitudes at a time. The horizontal lines which you see are called latitudes. The vertical lines are called longitudes which can be drawn at a particular angle. The end of longitudes define the poles are drawn using GL_TRIANGLE_FAN. Hope this helps.
