Revar Desmera	e550909726	Added some affine matrix generation optimizations.	2020-03-22 01:11:06 -07:00
Adrian Mariano	8fc3af0264	modified linear solvers to handle matrix RHS, added error checking to ... lerp and affine_frame_map, adde same_shape(), added square option to is_matrix.	2020-03-17 07:11:25 -04:00
Revar Desmera	265db9fe5d	Removed affine2d_apply() and affine3d_apply()	2020-03-15 11:50:41 -07:00
Revar Desmera	07bfcd6a57	Renamed normalize() to unit()	2020-03-02 19:30:20 -08:00
Adrian Mariano	ca167f6bb1	moved affine_frame_map to affine.scad	2020-02-29 22:54:33 -05:00
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.	2020-02-27 17:32:03 -05:00
