Now the following methods in the Freestyle Python API accept
not only Blender.Mathutils.Vector instances but also lists and
tuples having an appropriate number of elements.
FrsNoise::turbulence2()
FrsNoise::turbulence3()
FrsNoise::smoothNoise2()
FrsNoise::smoothNoise3()
SVertex::__init__()
SVertex::setPoint3D()
SVertex::setPoint2D()
SVertex::AddNormal()
FEdgeSharp::setNormalA()
FEdgeSharp::setNormalB()
FEdgeSmooth::setNormal()
CalligraphicShader::__init__()
StrokeAttribute::setAttributeVec2f()
StrokeAttribute::setAttributeVec3f()
StrokeAttribute::setColor()
StrokeVertex::setPoint()
* Added the following converters for the sake of the improvements
mentioned above.
Vec2f_ptr_from_PyObject()
Vec3f_ptr_from_PyObject()
Vec3r_ptr_from_PyObject()
Vec2f_ptr_from_PyList()
Vec3f_ptr_from_PyList()
Vec3r_ptr_from_PyList()
Vec2f_ptr_from_PyTuple()
Vec3f_ptr_from_PyTuple()
Vec3r_ptr_from_PyTuple()
Those converters with the suffixes _PyList and _PyTuple accept
only lists and tuples having an appropriate number of elements,
respectively, while those with the suffix _PyObject accept lists,
tuples, or Blender.Mathutils.Vector instances.
* Fixed a null pointer reference in Interface0D___dealloc__().
* Corrected the names of 3 methods in the FEdgeSmooth class.

and __call__ methods so that not only True and False but also various
other boolean expressions (e.g., 0, 1, and None) are accepted.

StrokeVertexIterator.
freestyle_init.py
* Added a generic getName() method that allows subclasses to omit the method to return their class names.
BPy_Convert.cpp
BPy_Convert.h
* Added to BPy_StrokeVertexIterator_from_StrokeVertexIterator() a second argument to specify the direction (reversed or not) of the iterator to be created.
BPy_Stroke.cpp
* Added support for Python's native iterator protocol.
* Added code to parse the optional argument of strokeVerticesBegin().
BPy_StrokeVertexIterator.cpp
BPy_StrokeVertexIterator.h
* Added support for Python's native iterator protocol.
Stroke.cpp
* Fixed a null pointer reference.
Stroke.h
* Added new method Stroke::strokeVerticeAt(i) that returns the i-th StrokeVertex of the Stroke.

has to be debugged. It can be activate in app_blender/api.cpp by replacing the FRS_scene_3ds_export call in FRS_prepare, by FRS_load_mesh.
All of the reference to the original Material class were renamed to FrsMaterial to resolve a name collision with Blender. To keep the window context necessary to draw the strokes after RE_Database_FromScene has been called, the display_clear function is used.
|
|
of the original styles are supported: stroke attributes are correctly taken into account, Python shaders are supported. Added SamplingShader.

modules having with strokes without a representation and iterators not being correctly routed. For example, the cartoon style module should work now.

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.

Material, Chain, FEdgeSharp, FEdgeSmooth. All Interface1D classes have now been fully implemented.
|
|
|
|
Modified functions accross API taking input boolean values.
|
|
parts of ViewVertex, SVertex and Convert to support these changes.
|
|
header positioning problems and adapted classes accordingly
|
|
SShape, ViewShape. Also corrected a few typos (Get#->get#).
|
|
Interface0DIterator, CurvePointIterator, StrokeVertexIterator, SVertexIterator, orientedViewEdgeIterator.
|
|
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.

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.

ModuleWrapper.cpp

source/blender/freestyle/intern/python. The migration will be based on source/blender/freestyle/intern/swig/ModuleWrapper.{cpp,h}
