DESCRIPTION
-------------------------------------------------------------------------------
Cogl is a small open source library for using 3D graphics hardware for
rendering. The API departs from the flat state machine style of OpenGL and is
designed to make it easy to write orthogonal components that can render without
stepping on each others toes.
As well as aiming for a nice API, we think having a single library as opposed
to an API specification like OpenGL has a few advantages too; like being
able to paper over the inconsistencies/bugs of different OpenGL
implementations in a centralized place, not to mention the myriad of OpenGL
extensions. It also means we are in a better position to provide utility
APIs that help software developers since they only need to be implemented
once and there is no risk of inconsistency between implementations.
Having other backends, besides OpenGL, such as drm, Gallium or D3D are
options we are interested in for the future.
REQUIREMENTS
-------------------------------------------------------------------------------
Cogl currently only requires:
• GLib ≥ 2.28.0
• OpenGL ≥ 1.3 (or 1.2 + multitexturing), or OpenGL ES 2.0 (or 1.1)
• GLX, AGL, WGL or an EGL implementation
Cogl also has optional dependencies:
• GDK-Pixbuf ≥ 2.0
- for image loading
• Cairo ≥ 1.10
- for debugging texture atlasing (debug builds only)
The optional Cogl Pango library requires:
• Cairo ≥ 1.10
• PangoCairo ≥ 1.20
On X11, Cogl depends on the following extensions
• XComposite ≥ 0.4
• XDamage
• XExt
• XFixes ≥ 3
When running with OpenGL, Cogl requires at least version 1.3
or 1.2 with the multitexturing extension. However to build Cogl
you will need the latest GL headers which can be obtained from:
http://www.khronos.org
If you are building the API reference you will also need:
• GTK-Doc ≥ 1.13
If you are building the additional documentation you will also need:
• xsltproc
• jw (optional, for generating PDFs)
If you are building the Introspection data you will also need:
• GObject-Introspection ≥ 0.9.5
GObject-Introspection is available from:
git://git.gnome.org/gobject-introspection
If you want support for profiling Cogl you will also need:
• UProf ≥ 0.3
UProf is available from:
git://github.com/rib/UProf.git
DOCUMENTATION
-------------------------------------------------------------------------------
The 1.x API is documented here:
http://docs.clutter-project.org/docs/cogl/1.10
The experimental 2.0 API is documented here:
http://docs.clutter-project.org/docs/cogl-2.0-experimental/1.10
RELEASE NOTES
-------------------------------------------------------------------------------
- This Cogl release exports a 1.x API (For third-party Clutter
developers to write custom actors) and an experimental 2.0 API which
allows standalone application development.
- Internally Clutter depends on the Cogl 2.0 experimental API so we maintain
runtime compatibility between the 1.x API and experimental 2.0 APIs, which
means developers can mix-and-match their use of the APIs in the same
process. API selection is done per-file by including a line like: '#define
COGL_ENABLE_EXPERIMENTAL_2_0_API' before including cogl.h or clutter.h.
- We recommend using the 2.0 API if you don't mind updating your code once in
a while as this API evolves and stabilizes. We promise not to break the 2.0
API during a 1.x stable cycle and hope that will encourage people to
experiment with it and give critical feedback! For example after releasing
1.8, the 2.0 API will be stable for 1.8.1, 1.8.2, 1.8.3 etc, but may update
for 1.9/1.10.
- Because we export the 1.x and 2.0 APIs from one libcogl.so the library
versioning, and thus ABI, can only be considered as stable as our 2.0 API -
i.e. during a stable release 1.x cycle.
