Clutter 0.3 ()
|
|
========================
|
|
|
|
* List of changes between 0.2.3 and 0.3
|
|
o Clutter now supports both switchable windowing system and GL backends.
|
|
Window systems supported include GLX, EGL and SDL.
|
|
|
|
GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
|
|
provided by a small basic abstraction layer 'cogl.h'. Cogl is not
|
|
yet documented - usage external to Clutter is not yet advised.
|
|
|
|
Backends may provide specific command line options.
|
|
|
|
Notes;
|
|
|
|
GLX
|
|
---
|
|
The GLX backend is built by default and is currently the most
|
|
developed, supported and featured windowing system backend. Only
|
|
OpenGL is supported via GLX.
|
|
|
|
SDL
|
|
---
|
|
Clutter has experimental support for using SDL. Open GL is supported as
|
|
is OpenGL ES via Dogles (very experimental).
|
|
|
|
EGL
|
|
---
|
|
Clutter has experimental support for using EGL. Only Open GL ES
|
|
is supported by EGL.
|
|
|
|
EGL support assumes an EGL implementation running atop X Windows.
|
|
|
|
Open GL ES.
|
|
-----------
|
|
|
|
Clutter now has experimental support for Open GL ES.
|
|
Current known issues;
|
|
|
|
+ Unrealising a ClutterTexture will not move pixel data from video
|
|
into system memory but simply destroy it.
|
|
+ BGRA, YUV Texture data not currently supported.
|
|
|
|
(Use the clutter_feature API to probe for above at runtime)
|
|
|
|
Open Source ES implementations this has been tested against
|
|
include `Vincent' and `dgles'. Support for commerical
|
|
implementations may require modifications to the configure.ac
|
|
script.

|
|
o New ClutterEffect class provides a simplified (and thus less flexible)
|
|
API wrapping around behaviours, alphas and timelines.
|
|

|
|
CLUTTER_ALPHA_SINE_INC

|
CLUTTER_ALPHA_SQUARE
|
|
CLUTTER_ALPHA_SMOOTHSTEP_INC
|
|
CLUTTER_ALPHA_SMOOTHSTEP_DEC
|
|
CLUTTER_ALPHA_EXP_INC
|
|
CLUTTER_ALPHA_EXP_DEC
|
|
o New Actors
|
|
+ ClutterContainer and ClutterVBox, ClutterHBox layout actors.
|
|
+ ClutterEntry, text entry actor
|
|
o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
|
|
o All internal math now fixed point based.
|
|
o Clutter now has it own internal event queue.
|
|
o ClutterStage new features;
|
|
+ Title property for naming in window decorations.
|
|
+ Perspective setting - The stages perspective can now be modified.
|
|
o New Clutter_actor *project API calls allow for querying of tranformed
|
|
actor vertices and points.
|
|
o New Clutter Feature checks.
|
|
o Initial ClutterUnit implementation for device independant positioning.
|
|
* List of Bugs fixed
|
|
o Various issues with very poor performance and Intel drivers.
|
|
o #138 Fix typo in x rotation transform.
|
|

|
|
|
|

|
|
==========================
|
|
|
|
* List of changed between 0.2.1 and 0.2.2
|

o Addition of basic XEMBED support for clutter stage. [Matthew]
|
|

|
|
|
|
* List of changed between 0.2.0 and 0.2.1
|
|
o Add even faster double to integer (and back) conversion
|
|
functions. [Tomas]

|
|
function. [Tomas]

|
|
Clutter 0.2 (18-01-2007)
|
|
========================
|
|
|
|
* List of changes between 0.2 and 0.1
|
|
o Bindings, GStreamer and GTK+ dependencies moved out of tree:
|
|
now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
|
|
o Actors now have an initial floating reference; this means you
|
|
don't have to explicitely unref them: every memory an actor
|
|
allocates will be freed when the group containing the actor will
|
|
be destroyed.
|
|
o Add basic run-time detection of GL features.
|
|
+ Use GL_TEXTURE_RECTANGLE_ARB if available.
|
|
+ Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
|
|
o Add API for behaviours. A ClutterBehaviour is an object which
|
|
drives a set of actors using one or more properties depending
|
|
on the value of an "alpha" function.
|
|
+ Provide simple behaviours: ClutterBehaviourOpacity,
|
|
ClutterBehaviourPath and ClutterBehaviourScale.
|
|
+ Provide simple alpha functions for ramps and sine waveforms.
|
|
o Add fixed point API for embedded platforms with no FPU.
|
|
o Add support for command line switches to Clutter, like debug
|
|
flags and abort on warnings; also allow application to hook up
|
|
into the initialisation sequence to add their own command line
|
|
switches.
|
|
o Add Pango GL renderer for Clutter, and use it to render text
|
|
inside the ClutterLabel actor; this decrease texture memory
|
|
usage.
|
|
o Redo Clutter Label widget, using the new Pango renderer.
|
|
o Clutter Textures do not store local pixbuf copy (of texture).
|
|
o Redo group and actor scale/sizing API and functionality.
|
|
o Add memory management API for ClutterColor, and string parsing.
|
|
* List of bug fixed
|
|
o #199 - Little group handling fix?
|
|
o #198 - Detect NPOT support on more systems
|
|
o #197 - Tiled textures are broken
|
|
o #196 - Rebuild the examples when the library changes
|
|
o #156 - clutter_actor_set_position not using the absolute size
|
|
o #155 - Don't test for XInitThreads [Bastien Nocera]
|
|
o #154 - Key presses not working in super-oh example [Bastien Nocera]
|
|
o #152 - Misc fixes [Bastien Nocera]
|
|
o #143 - Faulty ref-counting in clutter_group_remove [Frederic Riss]
|
|
o #141 - Copy-pasto in clutter_media_set_volume [Frederic Riss]
|
|
o #101 - No package 'x11' found -- wrong configure [Tomasz Torcz]
|
|
o #98 - Enabling trails in super-oh crashes
|
|
|
|

|
|
========================

|
|
|
* First 'official' release, expect bugs aplenty.
|
|
* Contains:
|
|
o Hopefully enough functionality to build things.
|
|
o Basic gstreamer 0.10 video playback support.
|
|
o Fairly stable API, though in no way totally stable.
|
|
Expect CHANGES in future versions.
|
|
o Some simple examples ( also see OPT ).
|
|
o An experimental GTK-Clutter widget.
|
|
o Fairly complete Python bindings.
|
|
o Non complete but hopefully useful API documentation.
