This allows manual (point by point) animation of their control verts,
although many other settings cannot really be animated with any
visible effects yet. Interestingly, lattices also had IPO block
pointers, though they were never really used (AFAIK).
Todo:
- Animation Editor support has yet to be added. I've got a few other
things to add to, so will group those changes together.
only tags the ID and does the actual flush/update delayed, before the next
redraw. For objects the update was already delayed, just flushing wasn't
yet.
This should help performance in python and animation editors, by making
calls to RNA property update quicker. Still need to add calls in a few
places where this was previously avoided due to bad performance.
* Property update functions no longer get context, instead they get only
Main and Scene. The RNA api was intended to be as context-less as
possible, since it doesn't really matter who is changing the property,
everything that uses the property should be updated.
* There's still one exception case that use it now, screen operations
still depend on context too much. It also revealed a few places using
context where they shouldn't.
* Ideally Scene shouldn't be passed, but much of Blender still depends on
it, should be dropped when we try to support multiple scene editing.
Change was planned for a while, but need this now to be able to call
update without a context pointer.
eg.
scene.objects.link()
object.constraints.new()
mesh.verts.transform(...)
mesh.faces.active
PropertyRNA stores an StructRNA pointer where these can be defined.
Notifiers
---------
Various fixes for wrong use of notifiers, and some new notifiers
to make things a bit more clear and consistent, with two notable
changes:
* Geometry changes are now done with NC_GEOM, rather than
NC_OBJECT|ND_GEOM_, so an object does need to be available.
* Space data now use NC_SPACE|ND_SPACE_*, instead of data
notifiers or even NC_WINDOW in some cases. Note that NC_SPACE
should only be used for notifying about changes in space data,
we don't want to go back to allqueue(REDRAW..).
Depsgraph
---------
The dependency graph now has a different flush call:
DAG_object_flush_update(scene, ob, flag)
is replaced by:
DAG_id_flush_update(id, flag)
It still works basically the same, one difference is that it now
also accepts object data (e.g. Mesh), again to avoid requiring an
Object to be available. Other ID types will simply do nothing at
the moment.
Docs
----
I made some guidelines for how/when to do which kinds of updates
and notifiers. I can't specify totally exact how to make these
decisions, but these are basically the guidelines I use. So, new
and updated docs are here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/NotifiersUpdateshttp://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers
* Reviewed subtypes, making them more specific and adding new ones.
* Subtypes now have an associated type of units (length, area, volume,
mass, rotation, time, velocity, acceleration). These are not used
yet anywhere.
* Centralized code that decides the name of array items based on
subtype (XYZ, RGB), was copied in 3 places.
* RNA_def_float etc functions still need to be update, will do this
later together with another change.
* support for dynamic enums to be inspected enumProp.items() from python.
* fix, enums check for a separator was flipped, meant no enums were in docs.
* dynamic enum functions now check for a NULL context and return all possible options for the "items" attribute used for docs.
* added an arg for rna arrays to free the array there looping over (needed to free dynamically allocated enum items)
* python api checks for NULL items since this can happen in some cases.
* python api, When getting an enum ID from an int in an array - If it failed it would get the first enum identifier and return that. Brecht? dont understand, making it return an empty string in these cases.
* Lattices: properties editable, editmode operators, menus working
again. As a bonus you can now edit u/v/w in editmode.
* Shape Keys: some code cleanup, and added more buttons. The
value/min/max buttons don't work correct yet though.
* Fix issue with uv textures, vertex colors not being visible outside
editmode, and a few other issue. Mesh.edit_mesh is now NULL when
not in editmode.
Merging changes made by Arystanbek in the soc-2009-kazanbas branch,
plus some things modified and added by me.
* The API files now all in the makesrna module, convention is to
call them e.g. rna_mesh_api.c for rna_mesh.c. Note for visual
studio build maintainers, the rna_*_api.c files are compiled as
part of "makesrna", but do not have rna_*_gen.c generated as part
of the library. SCons/cmake/make were updated.
* Added function flags FUNC_USE_CONTEXT and FUNC_USE_REPORTS, to
allow RNA functions to get context and error reporting parameters
optionally. Renamed FUNC_TYPESTATIC to FUNC_NO_SELF.
* RNA collections now have a pointer to add/remove FunctionRNA's, this
isn't actually used anywhere yet, purpose is to make an alias
main.meshes.add() for main.add_mesh() in python.
* Fixes to make autogenerating property set/get for multidimensional
arrays work, though a 4x4 matrix will be exposed as a length 16
one dimensional RNA array.
* Functions and properties added:
* Main.add_mesh()
* Main.remove_mesh()
* Object.matrix
* Object.create_render_mesh()
* WindowManager.add_fileselect()
* Added icon to property and enum property items. The latter is
responsible for the large number of files changed.
* For RNA functions, added PROP_RNAPTR flag to ask for a PointerRNA
as argument instead of a C pointer, instead of doing it implicitly
with the AnyType type.
* Material: properly wrap diffuse/specular param variables, and
rename some things for consistency.
* MaterialTextureSlot: added "enabled" property (ma->septex).
* Image: make animated property editable.
* Image Editor: make some things editable, notifiers, respect state.
* Context: fix issue with screen not being set as ID.
* Test with constructing RNA paths from pointer + property, based on
a callback per struct. For animato we'll need to be able to do this,
for keyframing from buttons, unless we can somehow derive the paths
from the interface code, which seems like an unnecessary burden.
However constructing such paths is not always quick, and we need a
fast way to find out if a property is animated for drawing buttons,
so this may not be the best solution.
See rna_mesh.c for some callbacks created as a test.
* Added BLI_sprintfN to mallocN a new string using printf style
formatting.
* Allow pointers to be editable, did SpaceTextEditor.text as a test.
* Changed PROP_NOT_EDITABLE to PROP_EDITABLE, and added
RNA_def_property_clear_flag.
* Removed rna_dependency.c test code.
* RNA_blender.h is now generated along with the other files. It is not
used anywhere yet, and still located quite hidden next to the other
rna_*_gen.c files. Read only access for now.
* Inherited properties are not copied from the base anymore but
iterated over. Patch by Vekoon, thanks!
* Array get/set callbacks now do the whole array instead of getting an
index. This is needed for some layers for example so python can set
the array as a whole, otherwise the check that one layer has to be
enabled at all times gets in the way. Also nicer for the C API.
* Also some changes to returning pointers to make the API cleaner, got
rid of the type() callback and instead let get() return PointerRNA
with the type included.
The C API looks like this currently:
http://users.pandora.be/blendix/RNA_blender.h
It's about time that the RNA wrapping for various parts of the animation system were cleaned up for my recent changes. I've moved some code around (and/or deleted a file or two) in the process.
* Finished DNA_lamp_types.h, DNA_world_types.h and DNA_sound_types.h.
* Renamed "parent" struct property to "nested", and also remaining "from"
usage to "base".
* Added a NEVER_NULL subtype for pointers and use it for all properties
that apply.
* Make sure all structs have a description, and fix any other DOC_BROKEN
descriptions, also many other naming consistency improvements.
* Added a function to define booleans negative, to turn negative
properties into positive ones gettin rid of the no_ prefix, and
also got rid of the use_ prefix for two booleans.
* Also made the function for enum bitflags separate, this is quite
rare so don't need to bother with this in most cases.
* Removed svn:executable flags from some files.
