create_mesh, create_dupli_list, make_display_list and is_visible.
This is done in order to make these context independent as the RNA API should
be as much as possible, and to fix#21297 and #21719, where there was an
assumption from these functions that there is a scene in the context, which
does not work for external render engines exporting in a separate thread.
Also avoided using context in a number of other functions, ideally only UI/WM
type functions should use context.
I've updated the scripts in trunk, but the addons and external ones in
development will need updates too.
Fixed and completed support for returning multiple values. This includes support for returning arrays, both fixed and dynamically sized. The way this is achieved is by storing an additional int value next to the dynamic parameter in the ParameterList stack which gets passed to the C function as an additional parameter. In the case of return parameters it is duty of the C function to set this int to the correct length value for the dynamic parameter (which makes sense). Note that for the dynamic output/return parameter it is assumed the function has allocated that memory (which gets freed automatically).
Also, I cleaned the makesrna's bridge function generation code a bit and renamed PROP_RETURN to PROP_OUTPUT, which represents better the reality now that there are multiple returns. The function now to mark multiple returns (outputs) is RNA_def_function_output.
For an example, look at Action.get_frame_range in rna_action_api.c, by the way Aligorith I removed the #ifdef for this function now that there's support for returning arrays, feel free to modify (the function seems to work).
Python Example.
hit_location, hit_normal, face_index = object.ray_cast(ray_start, ray_end)
- first rna func to use multiple return values
- currently casts in object space, may want to cast in worldspace too.
eg.
scene.objects.link()
object.constraints.new()
mesh.verts.transform(...)
mesh.faces.active
PropertyRNA stores an StructRNA pointer where these can be defined.
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
- Use CTX_data_main(C) over G.main
- no need to define object_type_items inline.
- rna_mesh.c - dynamic length array was commented out, not sure why this was needed. Povray and PLY scripts rely on faces having 3/4 verts rather then checking the 4th index is 0 (ok in C, not nice in py).
* copied I/O scripts
* copied, modified rna_*_api.c and rna_*.c
I/O scripts not working yet due to slight BPY differences and RNA changes. Will fix them later.
Not merged changes:
* C unit testing integration, because it is clumsy
* scons cross-compiling, can be merged easily later
- last commit, missed include for rna_object_api.c & bad args to find_basis_mball
- use enum for GHOST tablet type None/Stylus/Eraser, had duplicate definition for these in C. Only tested X11, may need to cast to an int for other OS's.
- povray converts curves to meshes on export, (metaballs don't need meshing).
- use 'extend' bool rather then 'seltype' enum for object_select operators for consistency.
- returned ID types from RNA funcs didnt get their ID's assigned which crashed in some cases (still not working for members of ID types).
- ob.create_remder_mesh() wasnt assigning any materials.
Unit tests:
- add a check that BKE_copy_images produces NULL filepath for images having type other than IMA_TYPE_IMAGE
- also expect NULL filepath for images having empty filename
Enhanced BKE_copy_images so the tests pass.
- added (uncommented actually) PoseChannel.pose_matrix
- added Object.dag_update that calls DAG_object_flush_update. I'm not sure if it's needed, but FBX exporter uses it.
Current issues:
- NURBS - needs API additions
- "all scenes" export - cannot switch scene in bpy
- normal calculation, disabled
- duplis - need testing, only dupliverts tested
- matrix problem
- UI, 18 options currently don't fit into filesel panel, will do manual lay out once it's available
- probably others...
BPY:
- made operator "execute" method required to avoid crash
- added bpy.sys module which replicates old "sys" module
API:
- replaced create_*_mesh with a single create_mesh accepting type parameter
- added Mesh.create_copy to create a copy of a mesh with 0 users
Ran `dos2unix` on source/blender/python/SConscript
* Main.remove_object
* Scene.add_object
* Scene.remove_object
* Object.convert_to_triface
* Object.create_preview_mesh
- a small tweak in set_mesh (blenkernel/inter/mesh.c) to make it work on objects having data == NULL
* Added optional params to Object.create_render_mesh(apply_matrix, custom_matrix)
apply_matrix is a boolean, True to transform mesh by ob->obmat or custom_matrix if given
* Fix subtle error in Object.create_dupli_list
* Make RNA struct funcs static, hopefully didn't miss any
Ignore export_obj-2.5.py changes for now ;)
- attempted to RNA-wrap DupliObject, Object.create_dupli_list returns a
collection of these.
Build fails probably because DupliObject is not defined in one of
DNA_*.h headers.
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()
