OpenGL teaching support

There are many online examples of OpenGL applications. Finding a well-prepared programs is difficult. Students starting with an OpenGL lack of clear and targeted examples. Therefore, I created a set of applications with an emphasis on simplicity. I established a new and modern criteria, which I implemented. Examples are designed for both fixed and programmable pipelines. For the creation were used less known, but new frameworks. Thus, there incept programs that are applicable to modern OpenGL. Architecture allows applications to be extended into larger projects. It provides operations such as loading textures or 3D models.
