Note: We should test if the armature is the "armature modifier" parent of the
object.
If any good samaritan feels like tackling this, the function to change
is: DRW_pose_mode_armature
We still need to bring pose bone drawing for the pose engine.
Note: In the future, once we get face-widget selection, we will need to
make sure the pose engien only draws then if "weight paint mode" is not
enabled too.
In the future this will allow us to implement things like face manipulators.
For now however, this is getting on the way of using pose mode
(mesh objects are drawn green).
NOTE: pose engine should also be the one taking care of pose bones
(and for that matter, X-Ray armature option should/could be a property
of the Pose engine even).
8b2640f08 introduced the error,
caused by external-engine needing depth mask to be disabled,
which happened to be the case before changing state changing logic.
Most of this was copying/adapting code from octahedral existing draw
code, tough part was to get BBone matrices to behave as expected, they
are using a fairly specific setup...
Addresses T51365 and T51362.
Changing states didn't properly reset between shading groups
causing the GL state to be wrong based on draw order.
States are now only set when changed.
We can now use object and other modes on top of Cycles.
Since we are now always on "render_to_view" (old Rendered mode), the
pause button is always visible.
- code_generate_fragment : Making sure that shaders uses the new uniforms.
- code_generate_vertex_new : create require attribute based on their names and not their id (see draw_cache_impl_mesh.c).
- add support for ramp textures.
This is a bad implementation waiting for some improvement that are :
- Gawain support for multiple names. -> will remove duplication of attribute alloc
- Glsl safe name string escaping. -> will remove any risk of hash colision.
Old glsl drawing was relying on attribute being choosen by DerivedMesh at drawing time.
For this reason, we declare all possible attrib "name" for each data layer inside the batches.
In the glsl code, we declare required data by type and name.
Then Gawain only bind vbos if names correspond.
This is way cleaner as we do not need to access the CD itself when drawing.
One other problem is that the hash maybe 11 caracters long and rapidly overload gawain's attrib name buffer.
- Unify GPUMaterial creation (world/mesh).
- Support for multiple shader variations (not used for now).
- Convert GPUInputs to DRWUniforms to be used with the draw manager.
- Nodetree Update is not supported. The only way to refresh the shaders is to change render engine.
- Cleanup in GPUPass.
- Add new temporary Node Compatibility type. Compatibility types should be removed in the future.
