Campbell Barton 4f8b7f4420 Docs: quiet warnings in reference doc syntax 2016-01-25 20:26:39 +11:00
Bastien Montagne e1b67c9bc0 Fix T46002: mathutils.geometry.intersect_line_line_2d doesn't operate on lines, but on line segments. 
Ugly issue really, but at least doc now matches behavior of the function. :|

Campbell Barton 1d71ad2eaa Math Lib: Use plane intersect from graphics-gems 2015-09-04 22:13:20 +10:00

Campbell Barton cff288cf3a Use PyC_ParseBool to parse bools 
This could cause problems since they could be any int,
then passed directly to internal functions that assume bools.

Tamito Kajiyama dbee634572 Fix typos. 2015-05-04 01:53:34 +09:00
Bastien Montagne 12a38abac6 Fix T43473: mathtutils.geometry.interpolate_bezier returns only 2d coordinates 
Fixed/enhanced a few usages of `mathutils_array_parse()` in this file actually...
 2015-01-29 18:11:13 +01:00
Bastien Montagne 90b5697459 Fix mathutils.barycentric_transform() 
Dummy typo, we need a 3D vector here...

Campbell Barton 1829c049be Correct args from recent mathutils refactor 2015-01-06 19:09:55 +11:00
Campbell Barton bf0c8e116d PyAPI: add PyList_APPEND 
This appends while giving ownership to the list, avoiding temp assignment.
This matches PyList_SET_ITEM which bypasses refcount's

Note, this also reduce code-size, Py_DECREF is a rather heavy macro.
 2015-01-06 19:09:53 +11:00
Campbell Barton 9fd569a654 PyAPI: add utilities PyTuple_SET_ITEMS, Py_INCREF_RET 
Setting all values of a tuple is such a common operation that it deserves its own macro.
Also added Py_INCREF_RET to avoid confusing use of comma operator.
 2015-01-06 19:09:11 +11:00
Bastien Montagne e0db0f84ac Fix T43119: mathutils.intersect_point_line always returns a 2D vector as first value. 
Trivial, safe for final 2.73.
 2015-01-04 10:11:21 +01:00
Campbell Barton 8106a6b75d mathutils: refactor instantiation 
remove 'type' argument, very few mathutils objects are wrapped,
add new function for creating wrapped objects.

also fixes unlikely memory leak if the data-array can't be allocated.

Campbell Barton cefb764269 PyAPI: geometry.normal, support polygons 
Previously this only supported tri/quads,
now arbitrary size poly lines are supported.
 2014-12-30 22:49:52 +11:00
Campbell Barton 68600920ce PyAPI: allow non-vector args for geometry module 
Previously only vector args were accepted,
now allow generic sequence of numbers.

Was annoying to create vectors just to pass in args.

Campbell Barton a7d8f602a6 Py/API: Improve intersect_line_line with parallel lines 
Now comparing the distance between line-intersection points
to see how close lines are - doesn't fail in the parallel case.

Campbell Barton 92d94ccb08 misc minor changes 
- make cmake osx use of -ftemplate-depth match scons.
- use array size within sizeof(), more compact.
- replace AT with __func__ where the function is unique enough.
- BLI_box_pack_2D -> 2d to match other functions.
- rename new mesh normal calculation to mesh.calc_normals_split()
 2013-09-10 19:23:39 +00:00
Campbell Barton 5dbe17cc12 add 2d convex hull utility function, BLI_convexhull_2d(), and python api mathutils.geometry.convex_hull_2d() 
uses Andrew's monotone chain 2D convex hull algorithm.
 2013-09-10 07:52:10 +00:00
Campbell Barton 8e46cf637c tweak mempool loop comparisons when we know there is no chance for skipping past the last value. 
also correct typo.
 2013-08-31 02:12:31 +00:00
Campbell Barton 11c988ba00 Simplify line/plane intersection, add line_plane_factor_v3(). 
Remove no_flip option for isect_line_plane_v3(), its quite specific and only used for ED_view3d_win_to_3d().
 2013-08-31 02:06:23 +00:00
Campbell Barton 09ff49755f math api edits - replace point-normal form for a plane with dist_to_plane_v3() 
also correct python mathutils api, was missing vector checks.
 2013-08-23 14:37:22 +00:00
Campbell Barton 7db1d6556d code cleanup: add break statements in switch ()'s, (even at the last case). 2013-07-21 08:16:37 +00:00
Campbell Barton 418011907c remove nan copyrights from code added since blender become opensource (copy paste errors), also remove BKE_script.h 2013-07-02 10:14:59 +00:00
Campbell Barton 5018ea5e29 real fix for [#35097], (curve cap flipping). 
previous commit was incorrect, the face flipping depended on the orientation of the curve.

fix by passing the bevel direction to the fill function so we can have a reliable front/back.

This also gives some speedup for all curve filling since we can avoid calculating the normal since its already known.

Campbell Barton c56a911cd9 style cleanup: comments 2012-10-20 20:20:02 +00:00
Campbell Barton 25c96bc9f3 code cleanup: remove unused macros, commet some which may be useful later - or good to keep for completeness. quieted some warnings and add flags -Wmissing-include-dirs and -Wno-div-by-zero to cmake/gcc 2012-09-20 01:02:39 +00:00
