## Cogl - a modern 3D graphics API

### About Cogl

Cogl is a modern 3D graphics API with associated utility APIs designed to expose the features of 3D graphics hardware using a more object oriented design than OpenGL. The library has primarily been driven by the practical needs of Clutter but it is not tied to any one toolkit or even constrained to developing UI toolkits.

## Cogl experimental API

### About the experimental API

Cogl has some experimental API developers are welcomed to play with. The main drawback when using those is that there is no API stability guarantee, functions flagged as experimental could be changed or removed in future versions of the library. To use this experimental API you will need to define `COGL_ENABLE_EXPERIMENTAL_API` before including `<clutter/clutter.h>` or `<cogl/cogl.h>`.

## Cogl deprecated API

### About the deprecated API

Cogl has evolved from once being a thin abstraction over OpenGL and GLES where a lot of OpenGL's state machine style APIs were simply rebranded as Cogl API into the more distinguished API style we have today. The result of this evolution though is that some of the APIs are considered deprecated and because we plan to remove them at the next opportunity we have to break the API developers should aim to avoid these functions to keep their code working with future major versions of Cogl.
