Magnum is 2D/3D graphics engine written in C++11 and modern OpenGL. Its goal is
to simplify low-level graphics development and interaction with OpenGL using
recent C++11 features and abstract away platform-specific issues.

Many engines out there were created as pure 2D or 3D and the alternative is
usually just an afterthought, if it is present at all. If you want to do

* **Forward compatibility**

the way to go. If you then really need to, you can selectively backport

using older functionality. However, you are not restricted to use the older
functionality directly, if you really want to.
* **Intuitive, but not restrictive API**
Scripting languages are often preferred to C/C++ because they tend to do
more with less -- less complicated APIs, nicer syntax and less boilerplate
code. Magnum is designed with scripting language intuitivity in mind, but
also with speed and static checks that native code and strong typing
offers. Usually the most common way is the most simple, but if you need
full control, you can have it.
