news 28 Posted September 24, 2013 Good news, everyone! A new Cogl release (1.16.0) is now available: LATEST NEWS ------------------------------------------------------------------------------- Cogl 1.16.0 2013-09-23 • List of changes since Cogl 1.15.10 » MSVC build updates » Correctly mark CoglAtlasTexture api as public » Lots of gtk-doc/introspection annotation fixes • Gnome Bugzilla bugs closed since 1.15.10: #704750 - egl: don't bind the wayland display if the extension is not available Many thanks to: Lionel Landwerlin Robert Bragg Chun-wei Fan Giovanni Campagna Neil Roberts FETCHING THE RELEASE ------------------------------------------------------------------------------- Tarballs can be downloaded from: http://download.gnome.org/sources/cogl/1.16/ SHA256 Checksum: 374c6548a7686c4cb3863f63b07b27d6e8a85e67a03f2a3a13a2789c59861c32 cogl-1.16.0.tar.bz2 Additionally, a git clone of the source tree: git clone git://git.gnome.org/cogl will include a signed 1.16.0 tag which points to a commit named: 05299fc2ea52a851cb597edc366ec50e31516c20 which can be verified with: git verify-tag 1.16.0 and can be checked out with a command such as: git checkout -b build 1.16.0 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: • 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: • GLib ≥ 2.32.0 - for gtype integration • 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 The optional Cogl GStreamer library requires: • GStreamer 1.0 On X11, Cogl depends on the following extensions • XComposite ≥ 0.4 • XDamage • XExt • XFixes ≥ 3 For the Wayland backend, Cogl requires: • Wayland ≥ 1.0.0 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 stable API is documented here: http://developer.gnome.org/cogl/stable/ The 1.x development API is documented here: http://developer.gnome.org/cogl/1.16 The experimental 2.0 API is documented here: http://cogl3d.org/cogl2-reference/ 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 up[censored] 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. - Please report bugs using the Cogl Bugzilla product, at: http://bugzilla.gnome.org/enter_bug.cgi?product=cogl _______________________________________________ Share this post Link to post
