* add some (disabled) test code for using OpenImageIO in imbuf
* link cycles, openimageio and boost into blender instead of a shared library
* some cmakefile changes to simplify the code and follow conventions better
* this may solve running cycles problems on windows XP, or give a different
and hopefully more useful error message
Note for VS2008 plus CMake users:
I had to remove OpenEXR debug libs from the "blender" project properties >
Linker > Additional Dependencies. Otherwise I got a number of linker errors
concerning duplicated symbols between libcmt.lib and libcmtd.lib.
Python:
* adds bpy.app.handlers which contains lists, each for an event type:
render_pre, render_post, load_pre, load_post, save_pre, save_post
* each list item needs to be a callable object which takes 1 argument (the ID).
* callbacks are cleared on file load.
Example:
def MyFunc(scene): print("Callback:", data)
bpy.app.handlers.render_post.append(MyFunc)
C:
* This patch adds a generic C callback api which is currently only used by python.
* Unlike python callbacks these are not cleared on file load.
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
this is not well suited to RNA so this is a native python api.
This uses:
bpy.data.libraries.load(filepath, link=False, relative=False)
however the return value needs to use pythons context manager, this means the library loading is confined to a block of code and python cant leave a half loaded library state.
eg, load a single scene we know the name of:
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.scenes = ["Scene"]
eg, load all scenes:
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.scenes = data_from.scenes
eg, load all objects starting with 'A'
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.objects = [name for name in data_from.objects if name.startswith("A")]
As you can see gives 2 objects like 'bpy.data', but containing lists of strings which can be moved from one into another.
CMake build option WITH_PYTHON_MODULE, will build ./bin/bpy.so
This allows 'bpy' to be imported from python or other applications/IDE's which embed python, eg:
python -c "import bpy ; bpy.ops.render.render(write_still=True)"
This runs in background mode and has similar restrictions to running a script:
blender --background --python test.py
TODO:
- install to site-packages with blender scripts
- add support for imp.reload()
A note for branch users: CMake 2.8 on 64-bit Windows Vista raised
an error in line 948 of soc-2008-mxcurioni/CMakeLists.txt due to
an invalid argument for the blender_include_dirs macro:
blender_include_dirs(${OPENGL_INCLUDE_DIR})
The command above should be:
blender_include_dirs("${OPENGL_INCLUDE_DIR}")
