This adds cogl_framebuffer_ apis for drawing attributes and primitives that replace corresponding apis that depend on the default CoglContext. This is part of the on going effort to adapt the Cogl api so it no longer depends on a global context variable. All the new drawing functions also take an explicit pipeline argument since we are also aiming to avoid being a stateful api like Cairo and OpenGL. Being stateless makes it easier for orthogonal components to share access to the GPU. Being stateless should also minimize any impedance miss-match for those wanting to build higher level stateless apis on top of Cogl. Note: none of the legacy, global state options such as cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or cogl_program_use() are supported by these new drawing apis and if set will simply be silently ignored.

<title>About Cogl</title>
|
|
|
|
<para>Cogl is a modern 3D graphics API with associated utility
|
|
APIs designed to expose the features of 3D graphics hardware
|
|
using a more object oriented design than OpenGL. The library has
|
|
primarily been driven by the practical needs of Clutter but it
|
|
is not tied to any one toolkit or even constrained to developing
|
|
UI toolkits.</para>
