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.

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.

buttons and mode flags, Freestyle API refactoring, modified pipeline to incorporate the new render layer. Compared to previously, the layer functionality is available when selecting 'Blender Internal' as the rendering engine. Freestyle's result is not available in the layer yet. I need to integrate OpenGL offscreen rendering properly (with framebuffer objects) to reach that goal.

AppGLWidget_Camera to use Blender's Camera struct, integrated the camera parameters from Blender. Perspective projection (precisely field of view) is now correct. Orthographic projection still having issues.

still a bit larger than Blender's internal renderer, probably a field of view problem). 3d scene is now no longer rendered, only 2d scene (strokes from view map information) is. Style module is still static (contour.py), will soon be handled via independent UI panel.
Phase 1 is considered finished. Phase 2 starts now: the objective is integrating Freestyle as an independent render layer.

app_blender/test_config.h). From now on, to use the branch, one needs to define a FREESTYLE_BLENDER_DIR environment variable to point to the Freestyle directory source/blender/freestyle

scene object), still with fixed style and fixed camera. Initialization is properly handled, which limits memory problems and speed-ups subsequent rendering. The viewing ratio should be correct now too. I also removed linking references to former lib3ds library path (caused some linking problems).

only rendering the strokes, not the toatl scene (explaining why the render color was being inverted). i added a call to the view's draw() method. Now, the rendering steps are complete and display both the object and the silhouette.

on a black background. The correction was made by following Yafray's rendering and display implementation, which is very clear.

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.

functions. The drawing still does not produce anything because the SWIG module wrapper is missing

Python environment.
I analyzed the crash with gdb and PyImport_AddModule ("__main__") in Python/import.c:320 seems responsible for the crash: apparently, "__main__" is not found and causes the error "No such file or directory".
I have to figure out what's wrong with the current configuration, especially whether Freestyle's PythonInterpreter can be used as is. I am going to see whether it's just quicker to use Blender's functions.

the following steps work:
1. instantiates the config path, the controller and the view
2. sets the controller’s view
3. loads a 3ds file (right now a fixed file)
4. inserts a style module (right now, also fixed)
5. computes the view map
The next and final step is running the Python script. A lot of information are fixed and should be changed to test the following code: see source/blender/freestyle/app_blender/*.cpp and search for fixed paths (starting in /Users/).
I am currently evaluating whether it's worth making Python run on its own environment (right now, the program crashes because of PyImport_AddModule) or whether it should use Blender's Python capabilities. Also, I need to figure out how to integrate the SWIG wrapper dynamic library into the current scheme.

this version yet :(

appglwidget corrected. Freestyle is called but cannot be linked (ImBuf issues). This is an unstable commit.
