4a3ecfe9ba Tweaked docs for reindex_polygon 2020-02-29 23:09:16 -05:00

7e0512e5f9 Bugfix for polygon_line_intersection() for failing to find intersection. 2020-02-28 21:37:16 -08:00
Adrian Mariano
f8fc8cb544 Adds sweep and new version of path_sweep to skin.scad, which probably 
needs a name change.  Adds apply(), apply_list() and
affine_frame_map() to affine.scad.  Adds derivative calcluation to
math.scad.  Adds path_tangent, path_normal, path_curvature and
path_torsion functions.  Adds path_length_fraction().
Fixed bug in reindex_polygon where it randomly reverses a 3d path (due
to clockwise check that is bogus in 3d) and put a check in
polygon_is_clockwise to trap this case.

d2ccdc331f Added get_height() and no_children() to common.scad. 
Changed the epsilon in one of offset's subfunctions from 1e-4 to

behavior if height is omitted.  It also quantizes the path to 1/1024.
Added no_children check to module offset_stroke().
