|
|
|
a coglsink element.
|

Cogl 1.17.2 2014-01-20
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.16.0
|
|
|
|
|
|
|
|
|
|
|
|
» Textures are now allocated lazily. This means the textures can
|
|
|
|
|
|
optionally be configured with extra API before data is uploaded to
|
|
|
|
|
|
them.
|
|
|
|
|
|
» The internal format for textures has been replaced with a simpler
|
|
|
|
|
|
property to just set the number of components that will be
|
|
|
|
|
|
required when sampling.
|
|
|
|
|
|
» Depth writing can now be disabled per-framebuffer as well as on
|
|
|
|
|
|
the CoglPipeline.
|
|
|
|
|
|
» The interface typedefs such as CoglTexture, CoglFramebuffer and
|
|
|
|
|
|
CoglBitmap etc are now defined as void so that it is no longer
|
|
|
|
|
|
necessary to use type-cast macros when passing them to interface
|
|
|
|
|
|
methods.
|
|
|
|
|
|
» YV12/I420 support in cogl-gst is fixed.
|
|
|
|
|
|
» Added support for red-green 2-component textures.
|
|
|
|
|
|
» The cache of GLSL shaders is now garbage collected when it gets
|
|
|
|
|
|
too large.
|
|
|
|
|
|
» cogl_framebuffer_push_path_clip is fixed.
|
|
|
|
|
|
» cogl-path is now split out into a separate library.
|
|
|
|
|
|
» New function cogl_wayland_texture_set_region_from_shm_buffer to
|
|
|
|
|
|
update a texture from a Wayland SHM bufffer.
|
|
|
|
|
|
» The pkg-config files for cogl-gst and cogl-gles2 have new more
|
|
|
|
|
|
consistent names.

Cogl 1.15.10 2013-09-02
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.15.8
|
|
|
|
|
|
|
|
|
|
|
|
» Added API to set the onscreen template on a CoglDisplay outside of
|
|
|
|
|
|
the constructor.
|
|
|
|
|
|
» Added public API to configure the layout of displays when using
|
|
|
|
|
|
the KMS winsys.
|
|
|
|
|
|
» Added a cogl_point_coord builtin variable for snippets which can
|
|
|
|
|
|
be used to render point sprites in more dynamic ways.
|
|
|
|
|
|
» cogl_texture_new_with_size now returns NULL on failure. This
|
|
|
|
|
|
behaviour was accidentally changed in 1.14.0.
|
|
|
|
|
|
» Fixed a problem with setting the precision specifiers on GLES2
|
|
|
|
|
|
which was causing a lot of problems with the latest Mesa.
|
|
|
|
|
|
» Added a “webgl” driver to manage the differences in GLES2 when
|
|
|
|
|
|
compiling with emscripten.
|
|
|
|
|
|
» Fixed a bug with paths which was causing Clutter's texture-fbo
|
|
|
|
|
|
test to crash.
|
|
|
|
|
|
» Some issues with introspecting the cogl-pango API were fixed.
|
|
|
|
|
|
» Added an example using point sprites.
|
|
|
|
|
|
» Build fixes for building with MinGW32.
|
|
|
|
|
|
» Updates to the MSVC build files.
|
|
|
|
|
|
» Documentation fixes to the snippets API.

|
|
Brown bag release to fix a problem with including cogl-path.h from
|
|
|
|
|
|
cogl.h that meant only code defining
|
|
|
|
|
|
COGL_ENABLE_EXPERIMENTAL_2_0_API would get access to the CoglPath
|
|
|
|
|
|
API.
|
|
|
|
|
|
|
|
|
|
|
|
We now ignore whether COGL_ENABLE_EXPERIMENTAL_2_0_API is defined so
|
|
|
|
|
|
clutter which does define it will see the api and so will clutter
|
|
|
|
|
|
users that don't define it.

|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.15.4
|
|
|
|
|
|
|
|
|
|
|
|
» Fixed runtime selection of egl-kms backend
|
|
|
|
|
|
» Split out the CoglPath api in-line with cogl master to reduce
|
|
|
|
|
|
divergence, but updated to not break the 1.x API/ABI
|
|
|
|
|
|
» Reverted the semantic change to cogl_offscreen_new_to_texture to
|
|
|
|
|
|
make it synchronously allocate as it did in cogl-1.14. A
|
|
|
|
|
|
replacement cogl_offscreen_new_with_texture api has been
|
|
|
|
|
|
introduced to support the asynchronous allocation behaviour
|
|
|
|
|
|
required to allow configuration of a framebuffer before
|
|
|
|
|
|
allocation.
|
|
|
|
|
|
» Fixed a problem with binding attribute locations with desktop GL
|
|
|
|
|
|
drivers, required to work with the latest Mesa.
|
|
|
|
|
|
» Some configure.ac documentation fixes
|
|
|
|
|
|
» In cogl-gst we make sure to only emit the "pipeline-ready" signal
|
|
|
|
|
|
once the new textures have actually been uploaded.
|
|
|
|
|
|
» Various MSVC build fixes
|
|
|
|
|
|
|
|
|
|
|
|
Note: we took some care to try and avoid breaking the ABI and
|
|
|
|
|
|
chaning the soname relative to the last 1.15.4 snapshot.

Cogl 1.15.4 2013-07-30
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.15.2
|
|
|
|
|
|
|
|
|
|
|
|
» Added experimental API to directly expose atlas textures.
|
|
|
|
|
|
» Added new_from_file/data/bitmap APIs for sliced textures.
|
|
|
|
|
|
» Added new_from_file APIs for 2D textures.
|
|
|
|
|
|
» Added cogl_primitive_draw as a new name for the
|
|
|
|
|
|
cogl_framebuffer_draw_primitive function.
|
|
|
|
|
|
» Removed the attribute drawing APIs. Instead applications should
|
|
|
|
|
|
create a primitive and draw that.
|
|
|
|
|
|
» Fixed bug where Cogl would busy-wait with 100% CPU if the Wayland
|
|
|
|
|
|
compositor is closed.
|
|
|
|
|
|
» The COGL_FRAME_EVENT_SYNC events are now sent based on the frame
|
|
|
|
|
|
callback with the Wayland backend.
|
|
|
|
|
|
» New cogl_gst_video_sink_is_ready() function to determine whether a
|
|
|
|
|
|
Cogl-GST video sink is ready to have the pipeline queried.
|
|
|
|
|
|
» Fixed a potential bug with the blending enabled state when copying
|
|
|
|
|
|
a pipeline.
|
|
|
|
|
|
» Fixed detecting the Mesa vendor when GL 3 is used.
|
|
|
|
|
|
» Fixed a reference leak on the CoglRenderer.
|
|
|
|
|
|
» Fixes to the Visual Studio build files.

Cogl 1.15.2 2013-07-09
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.14.0
|
|
|
|
|
|
|
|
|
|
|
|
» Lots of Wayland backend work, including updated compositor support
|
|
|
|
|
|
» Updated cogland, a simple example wayland compositor using Cogl
|
|
|
|
|
|
» Made the onscreen resize callback work the same as the frame callback
|
|
|
|
|
|
» New cogl_onscreen_swap_buffers_with_damage api
|
|
|
|
|
|
» New fence API
|
|
|
|
|
|
» New Emscripten support (only basic at the moment)
|
|
|
|
|
|
» Improved blend state tracking
|
|
|
|
|
|
» New cogl_onscreen_add_dirty_callback() api for window systems
|
|
|
|
|
|
that need to notify application of dirty/damaged regions that must
|
|
|
|
|
|
be redrawn by the application
|
|
|
|
|
|
» Started adding internal unit tests to complement the conformance
|
|
|
|
|
|
tests
|
|
|
|
|
|
» New support for per-vertex point sizes
|
|
|
|
|
|
» New cogl-gst sub-library added enabling gstreamer integration into
|
|
|
|
|
|
Cogl based applications. Notably the design is compatible with
|
|
|
|
|
|
applications adding custom shader snippets to a CoglPipeline that
|
|
|
|
|
|
handles video sampling so application will be able to chain
|
|
|
|
|
|
together shader based affects without requiring intermediate
|
|
|
|
|
|
renderers.
|
|
|
|
|
|
» Adds HSL color conversion apis
|
|
|
|
|
|
» The Conformance test suite can now be installed with a .test file
|
|
|
|
|
|
enabling them to be run by the gnome-desktop-testing-runner for example.

Cogl 1.11.6 2012-09-17
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.11.4
|
|
|
|
|
|
|
|
|
|
|
|
» Support latest libgbm api
|
|
|
|
|
|
» Improve error handling for cogl_texture_2d_new_from_foreign
|
|
|
|
|
|
» Avoid referencing contexts internally so Android
|
|
|
|
|
|
applications can reliably destroy the resources of a context without
|
|
|
|
|
|
us needing to introduce api to break internal circular references.
|
|
|
|
|
|
» More work to reduce our dependence on a global context internally.
|
|
|
|
|
|
» Recognize the latest Mesa GL vendor strings and the "Software
|
|
|
|
|
|
Rasterizer" renderer string.
|
|
|
|
|
|
» Improved cogl-gles2 support by not depending on drivers allowing
|
|
|
|
|
|
multiple vertex shaders in one program which isn't actually meant
|
|
|
|
|
|
to be supported in GLES 2.0 anyway. (We were lucky before because
|
|
|
|
|
|
Mesa happened to allow this but it doesn't work with other vendor
|
|
|
|
|
|
drivers.)

|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.10.0
|
|
|
|
|
|
|
|
|
|
|
|
» Adds cogl_framebuffer_{fill,stroke}_path APIs consistent with
|
|
|
|
|
|
other Cogl drawing APIs that replace cogl_path_fill/stroke().
|
|
|
|
|
|
» Switch from using glib types such as guint32/guint16/guint8 to
|
|
|
|
|
|
using equivalent stdint.h types.
|
|
|
|
|
|
» Adds a micro-benchmark for the journal
|
|
|
|
|
|
» Optimized the matrix stack so we can take immutable references
|
|
|
|
|
|
of a matrix stack for logging into the journal more efficiently
|
|
|
|
|
|
than having to copy large matrices for each journaled rectangle.
|
|
|
|
|
|
» Added COGL_VERSION_{MAJOR,MINOR,MICRO} macros and
|
|
|
|
|
|
COGL_VERSION_CHECK macros for applications to test what version
|
|
|
|
|
|
of Cogl they are compiled against.
|
|
|
|
|
|
» Allow creation of non power of two (npot) CoglTexture2D textures
|
|
|
|
|
|
with only basic npot support, not including repeating or mipmap
|
|
|
|
|
|
support.
|
|
|
|
|
|
» Enable use of the GL_STREAM_DRAW buffer update hint on GLES 2.0
|
|
|
|
|
|
» Fix building Cogl with --disable-gl
|
|
|
|
|
|
» Added support for the WebOS version of SDL which supports access
|
|
|
|
|
|
to GLES 1.1 and GLES 2.0
|
|
|
|
|
|
» Adds cogl_matrix_init_translation to provide a more efficient
|
|
|
|
|
|
way to initialize a matrix representing a translation without
|
|
|
|
|
|
need to multiply matrices.
|
|
|
|
|
|
» Various documentation fixes for CoglQuaternion and CoglEular
|
|
|
|
|
|
» Updates for the MSVC build

|
|
» Added GPU architecture detection capabilities so we can
|
|
|
|
|
|
differentiate drivers based on the hardware vendor, and the
|
|
|
|
|
|
actual architecture of the GPU, such as deferred vs immediate
|
|
|
|
|
|
mode.
|
|
|
|
|
|
» Fix framebuffer initialization to ensure swaps are throttled by
|
|
|
|
|
|
default.
|
|
|
|
|
|
» Fix flushing of the depth state for some cases.
|
|
|
|
|
|
» Ported test-atlas-migration to be a standalone Cogl test
|
|
|
|
|
|
» Added GLES 2.0 API integration support so that existing GLES 2.0
|
|
|
|
|
|
based code can easily be integrated within Cogl based
|
|
|
|
|
|
applications. For example this is being used by webkit-clutter to
|
|
|
|
|
|
add WebGL support.
|
|
|
|
|
|
» Added an optional libcogl-gles2 sub-library that provides a full
|
|
|
|
|
|
GLES 2.0 api api to really lower the barrier as much as possible
|
|
|
|
|
|
for being able to integrate existing GLES 2.0 based code into
|
|
|
|
|
|
Cogl applications.
|
|
|
|
|
|
» Adds a Cogl GLES 2.0 Gears example application to test the GLES
|
|
|
|
|
|
2.0 integration support.
|
|
|
|
|
|
» Fix a bug with disabling of Cogl's debugging features.
|
|
|
|
|
|
» Added api to directly convert a Eular to a Quaternion.
|
|
|
|
|
|
» Improve the wireframe debug option to work when a vertex shader
|
|
|
|
|
|
is in use.
|
|
|
|
|
|
» Added support for SDL2 which supports GLES 2.0
|
|
|
|
|
|
» Support the original GLSL extensions which had some different
|
|
|
|
|
|
function names.
|
|
|
|
|
|
» Avoid using eglGetProcAddress for core symbols which isn't allowed
|
|
|
|
|
|
by the EGL spec and causes problems on Android.
|
|
|
|
|
|
» Adds cogl_android_bitmap_new_from_asset() API to load images from
|
|
|
|
|
|
Android assets.
|
|
|
|
|
|
» Adds support for resizable onscreen framebuffers.
|
|
|
|
|
|
» Avoids implicitly including the EGL headers when including cogl.h
|
|
|
|
|
|
» Adds cogl.conf and environment variables to allow disabling the
|
|
|
|
|
|
use of specific GL extensions; for example if the implementation
|
|
|
|
|
|
is known to be buggy on a given system.

Cogl 1.10.0 2012-03-20
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.9.8
|
|
|
|
|
|
|
|
|
|
|
|
» Add cogl_framebuffer_draw_[*_]rectangle functions. These can be
|
|
|
|
|
|
used as a replacement for cogl_rectangle in the 2.0 API to avoid
|
|
|
|
|
|
the global framebuffer stack.
|
|
|
|
|
|
» Fixed flushing the point size with the GL driver when using GLSL.
|
|
|
|
|
|
» Added the missing cogl_is_onscreen and cogl_is_framebuffer functions.
|
|
|
|
|
|
» Added cogl_quaternion_init_from_quaternion and
|
|
|
|
|
|
cogl_quaternion_init_from_matrix to the public headers.
|
|
|
|
|
|
» Make cogl_has_feature available when only
|
|
|
|
|
|
COGL_ENABLE_EXPERIMENTAL_API is defined.
|
|
|
|
|
|
» Add cogl_framebuffer_read_pixels. This is a convenience wrapper
|
|
|
|
|
|
around cogl_framebuffer_read_pixels_into_bitmap to read directly
|
|
|
|
|
|
into an application's buffer.
|
|
|
|
|
|
» Added a public cogl_bitmap_new_for_data function. This can be used
|
|
|
|
|
|
for example to call cogl_framebuffer_read_pixels_into_bitmap to
|
|
|
|
|
|
read directly into an application's buffer with an unusual
|
|
|
|
|
|
rowstride.
|
|
|

Cogl 1.9.8 2012-03-05
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.9.6
|
|
|
|
|
|
|
|
|
|
|
|
» Various Visual Studio build fixes
|
|
|
|
|
|
» Correctly check for GL_EXT_packed_depth_stencil and support using
|
|
|
|
|
|
GL_OES_packed_depth_stencil on GLES2
|
|
|
|
|
|
» Correctly handle pre-multiplied alpha conversions when reading
|
|
|
|
|
|
back texture data.
|
|
|
|
|
|
» Added cogl_renderer_{get,set}_driver functions so the underlying
|
|
|
|
|
|
driver can be chosen programmatically.
|
|
|
|
|
|
» Revamped the conformance testing framework so that it
|
|
|
|
|
|
automatically runs every test against GLES2 as well as GL and also
|
|
|
|
|
|
against all of the pipeline backends and with npot textures
|
|
|
|
|
|
disabled.
|
|
|
|
|
|
» Add a conformance test for reading back an RGBA texture as
|
|
|
|
|
|
alpha-only
|
|
|
|
|
|
» Added support for converting between all of Cogl's supported pixel
|
|
|
|
|
|
formats including pre-multiplied alpha conversions.
|
|
|
|
|
|
» Added conformance tests for converting to and from all of the
|
|
|
|
|
|
supported formats.
|
|
|
|
|
|
» Added a public cogl_framebuffer_read_pixels_into_bitmap()
|
|
|
|
|
|
function which will effective read into a CoglPixelBuffer.
|
|
|
|
|
|
» CoglPixelBuffer was changed to no longer have associated width,
|
|
|
|
|
|
height and format information and instead we will rely on
|
|
|
|
|
|
CoglBitmap to track that informations. The relationship is
|
|
|
|
|
|
analogous how CoglAttributes relate to CoglAttributeBuffers
|
|
|
|
|
|
and means for example that a CoglPixelBuffer could now be used
|
|
|
|
|
|
to hold multiple images.
|
|
|
|
|
|
» Added public cogl_bitmap_get_{width,height,format,rowstride} api
|
|
|
|
|
|
» Added a public accessor for the underlying pixel buffer of a
|
|
|
|
|
|
CoglBitmap.
|
|
|
|
|
|
» Added various missing cast macros for some buffer objects.
|
|
|
|
|
|
» Ported the Clutter based test-pixel-buffer test to be standalone.

Cogl 1.9.6 2012-02-21
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.9.4
|
|
|
|
|
|
|
|
|
|
|
|
» New conformance tests or tests ported from Clutter:
|
|
|
|
|
|
test-offscreen
|
|
|
|
|
|
test-primitive
|
|
|
|
|
|
test-texture-3d
|
|
|
|
|
|
» New public experimental functions:
|
|
|
|
|
|
cogl_pipeline_get_layer_texture
|
|
|
|
|
|
cogl_primitive_copy
|
|
|
|
|
|
cogl_primitive_foreach_attribute
|
|
|
|
|
|
cogl_primitive_get_indices
|
|
|
|
|
|
cogl_pipeline_get_layer_{min,max}_filter
|
|
|
|
|
|
» Added cogl_kms_renderer_get_kms_fd to get the KMS file descriptor.
|
|
|
|
|
|
» Bug fixed in the KMS support where it would crash on cleanup if it
|
|
|
|
|
|
couldn't save the CRTC state.
|
|
|
|
|
|
» Bug fixed in the Wayland compositor support where it would leak
|
|
|
|
|
|
EGLImages when creating a texture from a buffer
|
|
|
|
|
|
» The swap_buffer callback in GLX is now delayed until
|
|
|
|
|
|
cogl_poll_dispatch is called so that apps can handle it more
|
|
|
|
|
|
predictably.
|
|
|
|
|
|
» Fixes for bugs with pipelines that are trying to use a layer with
|
|
|
|
|
|
a NULL texture.
|
|
|
|
|
|
» New cogl_framebuffer_* API for drawing directly to the framebuffer
|
|
|
|
|
|
without having to push the framebuffer. Ideally we want to move
|
|
|
|
|
|
towards this style of API in future with no global stacks.
|
|
|
|
|
|
» Most of the _EXP suffixes have been removed from the experimental
|
|
|
|
|
|
API symbols in the hope that the gtk-doc unstable annotation will
|
|
|
|
|
|
be enough to distinguish these.
|
|
|
|
|
|
» Add a COGL_DEBUG=winsys option
|
|
|
|
|
|
» CoglBuffer and CoglPrimitive now take an explicit CoglContext
|
|
|
|
|
|
argument in their constructor. We want to move towards getting rid
|
|
|
|
|
|
of the global context.
|
|
|
|
|
|
» Updates to the MSVC build support.
|
|
|
|
|
|
» Add cogl_pipeline_set_layer_null_texture(). This can be used for
|
|
|
|
|
|
base pipelines instead of having to create a dummy texture.
|
|
|
|
|
|
» Fix some bugs where Cogl was assuming there is a direct mapping
|
|
|
|
|
|
between the pipeline layer number and the GL texture unit number.
|
|
|
|
|
|
» In snippets, there are now always builtin sampler uniforms for
|
|
|
|
|
|
every layer of the pipeline. This makes it easier to write GLSL
|
|
|
|
|
|
that samples arbitrary units.
|
|
|
|
|
|
» The texture lookup snippet hook now gets passed the sampler for
|
|
|
|
|
|
the unit. The snippet can use this to sample the texture multiple
|
|
|
|
|
|
times.
|
|
|
|
|
|
» Some public constants for CoglPixelFormat have been removed
|
|
|
|
|
|
(COGL_UNPREMULT_MASK, COGL_UNORDERED_MASK and
|
|
|
|
|
|
COGL_PIXEL_FORMAT_{24,32}).
|
|
|
|
|
|
» 30-bit pixel formats added.
|
|
|
|
|
|
» COGL_DEBUG=wireframes now correctly renders primitives using
|
|
|
|
|
|
vertex shader snippets.
|
|
|
|
|
|
» cogl_framebuffer_swap_buffers and friends have been renamed to
|
|
|
|
|
|
cogl_onscreen_swap_buffers.
|
|
|
|
|
|
» If the experimental 2.0 API is requested, as far as possible the
|
|
|
|
|
|
headers for the 1.0 API are no longer included. Define
|
|
|
|
|
|
COGL_ENABLE_EXPERIMENTAL_API instead if you want to mix both APIs.

Cogl 1.9.4 2012-01-16
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.9.2
|
|
|
|
|
|
|
|
|
|
|
|
» Visual Studio 2008/2010 project files have landed and are being actively
|
|
|
|
|
|
maintained by Chun-wei Fan <fanchunwei@src.gnome.org>
|
|
|
|
|
|
» A basic KMS (Kernel Mode Setting) backend was added so we can run fullscreen
|
|
|
|
|
|
Cogl applications without X11 on Linux.
|
|
|
|
|
|
» EGL platforms can now be selected at runtime. Although we've had the ability
|
|
|
|
|
|
select backends at runtime for a while, up until now all EGL platforms were
|
|
|
|
|
|
part of one monolithic backend and were mutually exclusive so a platform
|
|
|
|
|
|
had to be chosen at build time.
|
|
|
|
|
|
» cogl_matrix_orthographic() was added as a replacement for cogl_matrix_ortho()
|
|
|
|
|
|
since the OpenGL style of arguments for cogl_matrix_ortho() wasn't consistent
|
|
|
|
|
|
with the rest of the Cogl API.
|
|
|
|
|
|
» Experimental cogl_framebuffer_ apis were added for manipulating the
|
|
|
|
|
|
per-framebuffer modelview matrix stack. The aim is for these to replace
|
|
|
|
|
|
apis like cogl_rotate/translate/scale because those apis aren't explicitly
|
|
|
|
|
|
related to a CoglContext which we'd like to avoid so we can remove the
|
|
|
|
|
|
need for a global CoglContext.
|
|
|
|
|
|
» Experimental cogl_framebuffer apis were added for manipulating the
|
|
|
|
|
|
per-framebuffer clip stacks.
|
|
|
|
|
|
» The internal _cogl_framebuffer_flush_state() function was optimized to do
|
|
|
|
|
|
a better job of bailing out when no framebuffer state has changed, and
|
|
|
|
|
|
when state has changed the cost should now scale by the number of changes
|
|
|
|
|
|
made instead of scaling by the total range of framebuffer state that Cogl
|
|
|
|
|
|
tracks.
|
|
|
|
|
|
» Internally we finally removed _cogl_enable() which won't mean much to most
|
|
|
|
|
|
people but makes the maintainers happy. This happened as part of a rework
|
|
|
|
|
|
for how attribute state is flushed when drawing which fixed some problems
|
|
|
|
|
|
with supporting custom attributes and should improve the performance of
|
|
|
|
|
|
flushing attributes too.
|
|
|
|
|
|
» We added an experimental CoglSnippets api aiming to greatly simplify how
|
|
|
|
|
|
developers can incorporate snippets of GLSL code into the pipeline. This is
|
|
|
|
|
|
a feature that has been on the drawing board for a long time so we're
|
2012-03-05 18:05:17 -05:00
|
|
|
|
really happy that it's finally here.
|
|
|
|
|
|
|
2012-01-16 18:18:18 -05:00
|
|
|
|
*** We'd really love to see people start to play with the snippets API and
|
|
|
|
|
|
tell us how they get on. The plan is for this API to replace all need for
|
|
|
|
|
|
developers to use the CoglProgram and CoglShader apis which are rather poor
|
|
|
|
|
|
copies of the OpenGL APIs for using GLSL which don't map well to Cogl's
|
|
|
|
|
|
design. ***
|
|
|
|
|
|
|
|
|
|
|
|
» We've updated Cogl's client side Wayland support
|
|
|
|
|
|
» We've updated Cogl's compositor side Wayland support, including updating the
|
|
|
|
|
|
example cogland compositor.
|
|
|
|
|
|
» We added an SDL window system backend for Cogl, which provides a simple,
|
|
|
|
|
|
portable way to play with Cogl as a standalone graphics API with basic
|
|
|
|
|
|
support for input events available from SDL. See examples/cogl-sdl-hello
|
|
|
|
|
|
to see how that works.
|
|
|
|
|
|
» We added mainloop integration support to Cogl. Since we want to have the
|
|
|
|
|
|
ability to use poll() to block for events from some drivers we have introduced
|
|
|
|
|
|
apis that all Cogl applications are required to use to integrate Cogl
|
|
|
|
|
|
into their mainloop. For applications using a glib mainloop we've provided
|
|
|
|
|
|
a GSource for convenience.

Cogl 1.9.2 2011-11-23
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.8.0
|
|
|
|
|
|
|
|
|
|
|
|
» Fix a crash while generating ARBfp code with layers containing a
|
|
|
|
|
|
NULL texture.
|
|
|
|
|
|
» Improvements to the mingw-fetch-dependencies script to work
|
|
|
|
|
|
without first needing to find a copy of config.guess.
|
|
|
|
|
|
» Translation updates.
|
|
|
|
|
|
» Ported more conformance tests from Clutter to be standalone Cogl tests.
|
|
|
|
|
|
» Adds experimental support for EXT_discard_framebuffer extension which
|
|
|
|
|
|
is important for good performance on PowerVR graphics hardware
|
|
|
|
|
|
» Adds experimental API to enable clipping to the silhouette of an arbitrary
|
|
|
|
|
|
2D CoglPrimitive
|
|
|
|
|
|
» Make the CoglTexture2DSliced API directly available as experimental API
|
|
|
|
|
|
» Adds a new feature checking API that's not limited to just 32 features
|
|
|
|
|
|
and also must be passed a CoglContext pointer so it's clear at what point
|
|
|
|
|
|
the features can start to be queried.
|
|
|
|
|
|
» Adds an experimental CoglMetaTexture interface that gives one simple
|
|
|
|
|
|
api for mapping meta-textures that aren't directly understood by the GPU
|
|
|
|
|
|
(such as sliced textures, atlas textures, sub textures) into low level
|
|
|
|
|
|
textures. This interface also gives us a single place to handle repeat
|
|
|
|
|
|
mode fallbacks, supporting clamp-to-edge, repeat and mirrored repeat.
|
|
|
|
|
|
» Make the CoglTextureRectangle API directly available as experimental API
|
|
|
|
|
|
» Adds experimental support for multisampling, which is where the gpu
|
|
|
|
|
|
calculates multiple samples per pixel and the final pixel is a weighted
|
|
|
|
|
|
average of those samples. For example you can expect that multisampling
|
|
|
|
|
|
with 4 samples per pixel would give similar quality to rendering at double
|
|
|
|
|
|
the resolution and then scaling that image down with texture filtering, but
|
|
|
|
|
|
the GPU can often do some tricks such that multisampling is faster than
|
|
|
|
|
|
doing that manually (known as supersampling)
|
|
|
|
|
|
» Make the CoglSubTexture API directly available as experimental API
|
|
|
|
|
|
» Added an n_indices argument to cogl_primitive_set_indices to avoid needing
|
|
|
|
|
|
to always call cogl_primitive_set_n_vertices() after using the api and
|
|
|
|
|
|
to make it less error prone to use the api.
|
|
|
|
|
|
» Ship a standalone cogl-xlib.h that must be included manually for any xlib
|
|
|
|
|
|
specific api because the Xlib headers so many numerous badly namespaced
|
|
|
|
|
|
symbols that it's not desireable to include them unless absolutely
|
|
|
|
|
|
required.
|
|
|
|
|
|
» Updated the Wayland support to work with the latest upstream interfaces.
|
|
|
|
|
|
» Add experimental CoglPipeline API for controlling the backface culling.
|
|
|
|
|
|
» Added a cogl_matrix_transpose() function
|
|
|
|
|
|
» Add experimental support for setting uniforms on a CoglPipeline. This
|
|
|
|
|
|
is in preparation for being able to associate snippets of GLSL that hook
|
|
|
|
|
|
into specific parts of the pipeline. We plan to eventually deprecate
|
|
|
|
|
|
CoglProgram but even in the meantime we would also recommend setting
|
|
|
|
|
|
uniforms on the pipeline now instead of the program.
|
|
|
|
|
|
» Adds experimental cogl_framebuffer_finish() api for explicitly synchonizing
|
|
|
|
|
|
the GPU with the CPU.

Cogl 1.8.0 2011-09-19
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.7.8
|
|
|
|
|
|
|
|
|
|
|
|
» Started porting Cogl conformance tests from Clutter to be standalone
|
|
|
|
|
|
Cogl tests including tests for depth-state and backface culling.
|
|
|
|
|
|
» Added a new color mask conformance test
|
|
|
|
|
|
» We no longer implicitly define COGL_ENABLE_EXPERIMENTAL_2_0_API in the
|
|
|
|
|
|
cogl-2.0-experimental.pc file cflags because the way pkgconfig works makes
|
|
|
|
|
|
it hard to then consume libraries depending on cogl-2.0-experimental.pc
|
|
|
|
|
|
with Clutter.
|
|
|
|
|
|
» Made progress re-factoring cogl-pipeline.c to be more maintainable by
|
|
|
|
|
|
starting to split the code up into more manageable pieces.
|
|
|
|
|
|
» We now bind the locale dir for the Cogl domain during init
|
|
|
|
|
|
» We now track backface culling state as part of CoglPipeline.

Cogl 1.7.8 2011-09-05
|
|
|
|
|
|
|
|
|
|
|
|
• List of changes since Cogl 1.7.6
|
|
|
|
|
|
|
|
|
|
|
|
» Getters for the display and renderer associated with context
|
|
|
|
|
|
» Getter for the number of supported texture units during fragment
|
|
|
|
|
|
processing. (ClutterGst needs to know this for example to know if GLSL
|
|
|
|
|
|
based YUV->RGB color space conversion can be used.)
|
|
|
|
|
|
» Optimizations for the GLSL codegen for fragment processing so we can
|
|
|
|
|
|
ignore redundant layers - if for example the "REPLACE" function is used
|
|
|
|
|
|
for layer N then computing anything for previous layers is redundant. Also
|
|
|
|
|
|
if texture combining needs to sample the same texture multiple times we
|
|
|
|
|
|
now re-use the same sample instead of repeating it.
|
|
|
|
|
|
» Optimize texture uploads to a texture atlas on GLES by avoiding lots of
|
|
|
|
|
|
redundant format conversions.
|
|
|
|
|
|
» Relax the requirement to need braces around blend factors when using the
|
|
|
|
|
|
CoglBlendString syntax. Braces are only needed for factors involving a
|
|
|
|
|
|
subtraction like "(1 - SRC_COLOR[A])"
|
|
|
|
|
|
» Adds API for querying the format of a CoglFramebuffer
|
|
|
|

Cogl 1.7.4 2011-07-20
|
|
|
|
|
|
===============================================================================
|

|
|
|
|
|
|
|
• List of changes since Cogl 1.7.2
|
|
|
|
|
|
|
|
|
|
|
|
» Optimize pipeline unparent operation using embedded lists instead
|
|
|
|
|
|
of using GList API.
|
|
|
|
|
|
» Remove the old matrix operation code we had before pulling in the
|
|
|
|
|
|
mesa based code, and flatten all our matrix utilities back into one
|
|
|
|
|
|
maintainable file.
|
|
|
|
|
|
» Expose cogl_framebuffer_get_red/green/blue/alpha bits to query
|
|
|
|
|
|
the precision for a framebuffer's color channels.
|
|
|
|
|
|
» Numerous reference manual updates
|
|
|
|
|
|
» Fix some memory leaks in CoglPipeline that weren't captured in
|
|
|
|
|
|
bugzilla.
|
|
|
|
|
|
» Fix some EGL winsys issues that weren't captured in bugzilla.
|
|
|
|
|
|
» Switch to dynamically loading libGL, libGLESv2 or libGLES[v1]_CM
|
|
|
|
|
|
at runtime so it's possible to distribute a libcogl that can choose
|
|
|
|
|
|
to work with any of these at runtime. This can simplify packaging
|
|
|
|
|
|
on distros that have numerous packages that provide a platform
|
|
|
|
|
|
specific GL/GLES driver and certainly helps during the development
|
|
|
|
|
|
process when evaluating the pros-and-cons of different drivers for
|
|
|
|
|
|
a given platform.
|
|
|
|
|
|
» Clean up lots of inconsistencies with platform specific APIs, so
|
|
|
|
|
|
we follow the naming convention of cogl_<platform>_object_method.
|
|
|
|
|
|
» Remove cogl_set_default_context from experimental 2.0 api, since
|
|
|
|
|
|
we are aiming to remove the default context for 2.0
|
|
|
|
|
|
» Ensure the experimental 2.0 reference manual gets a unique
|
|
|
|
|
|
DOC_MODULE name so that distro's trying to package cogl don't end
|
|
|
|
|
|
up installing the 1.x and 2.0 manuals to the same location
|
|
|
|
|
|
» Add a program cache for the GLSL backend, a bit like we have for
|
|
|
|
|
|
the ARBfp backend. This can be a big boost in performance for some
|
|
|
|
|
|
apps depending on your platform.
|
|
|
|
|
|
» Adds dither_enable getter and setter API for CoglFramebuffer so
|
|
|
|
|
|
that Clutter doesn't need to use the GL API directly when picking.
|
|
|
|
|
|
We need to get to the point where Clutter doesn't need to link
|
|
|
|
|
|
against libGL directly so Clutter can take advantage of runtime
|
|
|
|
|
|
driver selection by Cogl.
|
|
|
|
|
|
» Use MESA_pack_invert extension in cogl_read_pixels to avoid
|
|
|
|
|
|
needing to manually flip pixel data read in bottom-up order to a
|
|
|
|
|
|
top-down order.
|
|
|
|
|
|
» Fix the hello example to actually clear the framebuffer at the
|
|
|
|
|
|
start of the frame instead of unintentionally relying on the driver
|
|
|
|
|
|
to have cleared the framebuffer.

|
|
|
» Add an example program to draw a 3D crate
|
|
|
|
|
|
|
|
|
|
|
|

|
|

|
|

|
|
|
|
|
» Rename platform-specific APIs so that we consistently have

|

cogl_<platform>_symbol_name instead of cogl_symbol_name_<platform>.
|
