If you need to manage graphics, images such as jpeg, png, gif images or pictures of any kind, or handle animation in your programs, including writing games, drawing 3d or 2d pictures, you might like to consider the graphics libraries, 3d engines, 2d engines, image manipulation source code etc listed here. Computer graphics lecture notes university of toronto. Lower level youll find libxmi and libart from the gnome project. In computer graphics software, 2d applications may use 3d techniques to achieve effects such as lighting, and, similarly, 3d may use some 2d rendering techniques. We can classify 2d vector graphics rendering algorithms into two types. This notion of cross product does not make sense in 2d space, since it is not possible for a third 2d vector to be perpendicular to two non parallel 2d vectors. In the scaling process, we either compress or expand the dimension of the object.

So you still need to ensure that memory will be created for your vectors. How to create and use scalable vector graphics svg in.
