* Removed the ../include and ../src include directories from scons/cmake files.
These directories do not exist and are very noisy when building.
* Coding style clean-up in Python scripts: 'string' is used for enum values,
and "string" for usual stings.
* UILayout.active is used instead of UILayout.enabled to grey out "inactive"
settings. This still allows users to edit them, which can be handy sometimes.
* Improved UI layout of the Line Style panel by means of:
- The standard “column” paradigm is used in more places;
- More compact layout where possible; and
- Tweaks to the modifiers' header.
* Improved UI layout of the Line Set panel by rearranging the "Selection by"
options into a compact row of toggle buttons.

from within style modules. Calling this function is only valid within
style modules. Calling it from the Python Interactive Console results
in an error as follows:
>>> import Freestyle
>>> Freestyle.getCurrentScene()
Traceback (most recent call last):
File "<console>", line 1, in <module>
TypeError: current scene not available
>>>
|
|
The issue was caused by the order of libraries given to the linker. More
specifically, libbf_python.a should precede libbf_freestyle.a, which is
assured by choosing an appropriate 'priority' value of a BlenderLib.

- proper Freestyle initialization, with support for undo/redo
- re-added FreestyleStyleConfig data structure
- Freestyle Python interpreter updated
This commit should compile without errors. More work is necessary to complete the migration:
- add Freestyle in the UI
- set up RNA support

classes, except EdgeModifier and TimestampModifier (which aren't even ported via SWIG), are available under the Blender.Freestyle module. Testing of the porting will now begin to make sure the SWIG-less system works as the original.
Quite a few modifications were made to finish the API:
- Freestyle's SConscript was modified to catch all files within the intern/python directory, allowing integration of future shaders implemented in C++.
- the Operators class was ported, with a special care of making its methods static (using the METH_STATIC flag in the tp_methods method definitions)
- all of the type-checking functions [ BPy_[class name]_Check(obj) ] were changed to allow subclasses to be seen as that type too: instead on looking at the ob_type value, the PyObject_IsInstance function is used.
- all of the iterators can now retrieve the object pointed to by the operator, using the getObject() method. A directedViewEdge pair is returned as a list of the two elements in the pair.
- all of the style modules were copied to a style_modules_blender/ folder and were modified to use Freestyle as a Blender's submodule. IntegrationType and MediumType was also integrated (for example, changing MEAN to IntegrationType.MEAN).
Testing now begins. If everything works correctly, I'll move on to lib3ds removal right away.

Freestyle (on the C++ side). Created the equivalent in Python BPy_Iterator with the simple interface:
- getExactTypeName()
- increment()
- decrement()
- isBegin()
- isEnd()
Contrary to previously stated, I am reverting back to implementing iterators in the (Python) API, for different reasons:
- it will make testing quicker to achieve, as I won't have to recode a big chunk of the original Python files
- it will be a base for API refactoring
- it won't prevent the use a list-based approach later (it is simple to get it from the Iterator)

prefix to avoid library name collision.
Included MediumType's initialization at proper time to avoid Blender's crash.
|
|
MediumType (used by Stroke to define medium types) classes. The Stroke class is missing the InsertVertex method.
Before porting other classes, I'll resolve the List (Python) <=> Iterator (C++) correspondence problem by implementing a general class appropriately suited for the task.

IMPORTANT: The setters functions' names were normalized due to constant confusion regarding capitalization. All the function names start with set... instead of Set.... This convention was changed all throughout Freestyle. To use Freestyle as an external renderer, the SWIG library MUST be regenerated.

passing-by-reference format. Improved the type checking for FEdge and CurvePoint. Modified FEdge C++ class to test for null vertices. Updated previous classes to support FEdge.
So far, whenever a Python object is created from its corresponding C++ object, the input object reference is copied into a new object. Due to Freestyle's functions (especially regarding the way it is iterated), it is currently impossible to deal with a pointer-based Python object. It is not a real drawback, just an aspect to keep in mind.

migration. Stabilized a lot of the code for C++ -> Python conversion. Added the correct rich comparison operator and tested it. Corrected 'dupplicate' typo and changde to __copy__ for Python API.
From now on, when a set should be output (PySet_Type), it is given as a list (PyList_Type). The reason is that it doesn't really matter what we bring back to the Python interpreter. The set is guaranteed in memory on the C++ side.
For the CurvePoint class, the userdata variable is not yet ported (and will probably available as a list or a dictionary). The CurvePoint implementation works except for the initialization from other CurvePoints: somehow, the inner variables don't seem to be correctly handled. I do not know if it is a bug in Freestyle or if the CurvePoint object's state is correct for my test case. CurvePoint needs more testing.

classes. The Python object type tp_new slot is now set to PyType_GenericNew, instead of the former custom functions. As a note, by default, Python does not set this slot: it is therefore mandatory for the base classes. For children classes, only __init__ is needed.
To make our base classes subclasses, the Py_TPFLAGS_BASETYPE flag was added to the object type tp_flags slot.
Finally, I began to implement CurvePoint, descendant of Interface0D. This commit allowed me to verify that my SWIG replacement method works: interfaces are well taken into account by children. For a test, use the following code:
================================
import Blender
from Blender import Freestyle
from Blender.Freestyle import *
print Interface0D()
print CurvePoint()
================================
The __repr__ method is only implemented in Interface0D:
PyObject * Interface0D___repr__(BPy_Interface0D* self)
{
return PyString_FromFormat("type: %s - address: %p", self->if0D->getExactTypeName().c_str(), self->if0D );}
and the result is of the form:
type: Interface0D - address: 0x18e5ccc0
type: CurvePoint - address: 0x18e473f0
As you can see, the correct getExactTypeName of the class is called.

Freestyle module is added. The following modules are implemented: BinaryPredicate0D, BinaryPredicate1D, Id, Interface0D, Interface1D. I added a Convert module to help in the creation of Python objects for Freestyle's data structures. I also added a missing file for guarded_alloc needed for compilation on Windows.

paper texture loading. The canvas view now has its frame properly initialized to fixed dimensions. When the Freestyle render is executed, the render is displayed for a fraction of a second and is then erased by a standard gray background. I have to analyze what command I need to call to keep the result on display.

loads appropriate modules, using SWIG wrapper), but does not render anything yet (render window OpenGL context not used yet). Currently, the SWIG wrapper library needs to be manually compiled (see SWIG section in source/blender/freestyle/SConscript for details). I am missing some knowledge on scons to create it automatically from the SConscript. Once I find that information, I'll make it automatic and for different platforms.
I also corrected a simple GLStrokeRenderer bug for texture loading (not in original Freestyle code). Apparently, IMB_loadiffname doesn't recognize the paper's texture depth so a work-around will have to be found.

initialization (in accordance with original Freestyle code). This is achieved by creating a temporary Text structure, adding the required import and appending the necessary Python path. The text is executed using the BPY_txt_do_python_Text command.
When Freestyle is run within Blender, it should not crash; the Python interpreter should report an ImportError on _Freestyle (the SWIG wrapper).
