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.

|
environment variable.
