>From a quick test of these scripts, 3 issues came up, #1 & #2 are not blocking,
but would want to see #3 resolved before inclusion by default.
1) own math lib.
Bevel defines its own simple math functions.
cross2D, dot2D, triangle_normal, axis_angle_to_quat,
rotation_between_vectors_to_quat, intersect, these are defined in
mathutils.
mathutils docs: http://www.blender.org/documentation/250PythonDoc/mathutils.html
va module: https://svn.blender.org/svnroot/bf-extensions/contrib/py/scripts/addons/mesh_bevel/va.py
Unless there is some problem in mathutils that cant be resolved I'd
rather not have scripts having their own math libs.
2) speed.
IMHO python is not well suited to writing mesh tools, at least not
when realtime updates from sliders is expected.
on a 4k poly mesh the bridge tool took ~4-6sec per update on my 'AMD
Phenom II X6 1055T' cpu.
Having tools which are mainly suitable for low poly modeling is fine
but I would rather they not be enabled by default.
3) polluting custom properties.
operator settings, vertex induces , and version info is written into
objects custom properties.
This gives nice user experience but I rather we have a better way to
save operator settings then each tool dumping data into the objects
metadata (especially mesh data). See below.
Since custom properties will be saved permanently in blend files I
think this really needs to go before accepting into trunk addons,
possible solutions are to remove this feature or store cache in the
python module which means at least its not saved into the blend file
and data is local to the module.
Bridge tool metadata from bridging 2 circles:
