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.
UnaryFunction0D and UnaryFunction1D implementations are going to be really challenging due to the changes in the infrastructure: UnaryFunction0D<T> and UnaryFunction0D<T> are templates and must be determined for compile-time. The easiest solution is to support each type individually; unfortunately, it removes the benefit of using an interface. To find a middle ground, a general unary function Python object type was created for 0D and 1D. In both cases, the types have a void* pointer keeping the address of the current unary function type. I am not sure yet if it will work.
Interface0DIterator being removed by a list type, the t() and u() coordinate functions will to be transferred somehow, probably directly at the Interface0D level.
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.
Interface0DIterator was modified to allow BPy_Interface1D to be instantiated: verticesBegin(), verticesEnd(), pointsBegin(float) and pointsEnd(float) are not pure virtual functions anymore. If they are called directly from BPy_Interface1D (instead of its subclasses), an error message is displayed.
