2013-10-05	rename overlap to holes for isect_point_poly_v2	Campbell Barton

2013-10-04	code cleanup: warnings and minor edits.	Campbell Barton

2013-10-04	fix for lasso failing/glitches on overlapping lines, replace scanfill with ↵	Campbell Barton
	2d pixel filling for drawing and selection.
2013-10-04	fix for lasso selection (in non-zbuf mode) when the line intersected its self.	Campbell Barton
	isect_point_poly_v2() - add argument to check overlapping areas.
2013-09-25	fix error where BKE_mesh_cd_validate layer renaming would use invalid index ↵	Campbell Barton
	values. from r60260 also correct some comments.
2013-09-14	minor changes needed for building standalone mathutils.	Campbell Barton

2013-09-07	missing NULL check in recent commit, also skip some calculations in ↵	Campbell Barton
	mean_value_half_tan functions for degenerate cases.
2013-09-06	fix for barycentric_weights_v2_quad() divide by zero when the location we're ↵	Campbell Barton
	checking the weight of touches one of the weighting coords exactly.
2013-08-31	Simplify line/plane intersection, add line_plane_factor_v3().	Campbell Barton
	Remove no_flip option for isect_line_plane_v3(), its quite specific and only used for ED_view3d_win_to_3d().
2013-08-30	Some knife fixes. Avoids duplicating verts; better handling of cut-through ↵	Howard Trickey
	ortho. Now cut lines detect vertices that they pass (almost) exactly over and snap to them, to avoid making verts vert close to other ones. Added radius arg to BKE_bmbvh_ray_cast so that can detect an obscuring face when the ray might otherwise go exactly between two triangles. Needed an isect_line_tri_epsilon function for similar reason. Fixes last part of bug #35002. Other knife bugs still present but getting this commit in now before continuing bug fixing.
2013-08-23	simplify dist_to_plane_v3 and add dist_squared_to_plane_v3	Campbell Barton

2013-08-23	math api edits - replace point-normal form for a plane with dist_to_plane_v3()	Campbell Barton
	also correct python mathutils api, was missing vector checks.
2013-08-23	modify closest_to_plane_v3 not to use point-normal form.	Campbell Barton

2013-08-22	add utility functions for dealing with planes	Campbell Barton
	- plane_point_side_v3(), a bit like line_point_side_v2() - isect_point_planes_v3(), moved from paint_hide.c functions to convert between point/normal pairs. - plane_from_point_normal_v3() - plane_to_point_normal_v3()
2013-08-22	minor internal change: isect_point_poly_v2 was assigning a value past the ↵	Campbell Barton
	array bounds, not that bad since it wasn't read but this isnt good practice and its simple to avoid.
2013-08-01	code cleanup: remove unused functions	Campbell Barton
	- IsectLLPt2Df - isect_point_quad_uv_v2 - isect_point_face_uv_v2 These are obsoleted by resolve_tri_uv, resolve_quad_uv also add attributes for unused function results for some math functions.
2013-07-19	code cleanup: avoid sqrt in isect_seg_seg_v2_point	Campbell Barton

2013-07-12	optimize interp_weights_poly_v2(), well tested, was calculating the area ↵	Campbell Barton
	twice as much as was needed.
2013-07-11	fix [#36105] Bevel UV Flicker	Campbell Barton
	interp_weights_poly_v2/3 functions used much too small an epsilon value, caused flickering.
2013-07-05	fix [#35987] bevel gives nan vertices	Campbell Barton
	The line intersection function bevel uses could give nan intersections.
2013-06-26	correct typos in comments.	Campbell Barton

2013-06-21	Code cleanup: fix some vs2012 compiler warnings	Brecht Van Lommel

2013-06-10	code cleanup: use boolean for intersection functions.	Campbell Barton

2013-05-10	Optimize BKE_mesh_calc_normals(), gives approx 25% speedup.	Campbell Barton
	- no need to allocate polygon normal array. - no need to use BLI_array_ functions (realloc's). - reduce some of the looping.
2013-05-03	knife sort_by_frac_along was re-calculating the reference factor for every ↵	Campbell Barton
	test, change to only calculate once and use line_point_factor_v3(). also add zero division check for line_point_factor_v3() since the 2d version already checked for this.
2013-04-22	add clip_segment_v3_plane_n() to clip a line segment to planes (as used for ↵	Campbell Barton
	view clipping). use in ED_view3d_win_to_segment_clip() and fix error, was clipping by only 4 planes rather then 6.
2013-04-22	code cleanup: remove duplicate function _det_m3(), clip_line_plane was ↵	Campbell Barton
	copying a vector for no reason.
2013-04-21	utility function volume_tetrahedron(), for mathutils and BLI math.	Campbell Barton

2013-03-21	code cleanup: use bool where values are true/false, for view3d and related ↵	Campbell Barton
	functions.
2013-03-15	move polygon intersection out of BLI_lasso into BLI_math_geom since its a ↵	Campbell Barton
	generally useful function. adds: - isect_point_poly_v2() - isect_point_poly_v2_int()
2013-03-14	tweaks to clang so blender can build with -Werror	Campbell Barton

2013-03-09	code cleanup: favor braces when blocks have mixed brace use.	Campbell Barton

2013-03-07	math: Use len_v3() instead of normalize_v3() for area calculation	Sergej Reich
	We only need the length, avoids unnecessary calculations.
2013-03-03	code cleanup: ~400 duplicate lines for AO form factor math.	Campbell Barton

2013-02-19	make asserts that check for unit length vectors into a macro.	Campbell Barton
	this was really not nice logic to try to fit into an assert.
2013-02-14	Fix "Origin to Center of Mass" not working well with ngons	Sergej Reich
	Now we do simple triangulation and calculate signed area of triangles to account for concave polygons. This only works correct for planar polygons but gives better results overall.
2013-02-14	Divide by 3 instead of multiplying by variations of 0.333	Sergej Reich
	Fixes small precision problems.
2013-02-14	modify own changes to is_quad_convex_v3() to allow quads with a co-linear ↵	Campbell Barton
	side to be considered convex (as it did in last release). this is needed so zero area faces be dealt with by beauty fill.
2013-02-13	make is_quad_convex_v3() more strict, check if normal is OK before using as ↵	Campbell Barton
	a rotation axis. make is_quad_convex_v2,3() check for ISECT_LINE_LINE_CROSS intersection (that the lines actually cross each other).
2013-02-09	fix for is_quad_convex_v3(), getting the dominant axis wasn't accurate ↵	Campbell Barton
	enough in some cases and would make beauty fill fail. now rotate the coords before calculation.
2013-02-03	add dist_to_line_v3() for completeness, (had dist_to_line_v2 already)	Campbell Barton

2013-02-02	style cleanup	Campbell Barton

2013-01-10	bmesh todo: uv stretch area draw mode wasn't calculating ngon area - added ↵	Campbell Barton
	area_poly_v2().
2013-01-08	style cleanup	Campbell Barton

2013-01-08	comment fix.	Antony Riakiotakis
	Looks like no scaling is done elsewhere on blender for this code. I hope this bug is squashed for good.
2013-01-08	* Fix for #31581. The issue was that we scaled the face prior to	Antony Riakiotakis
	projecting it. The original paper suggests to simply interpolate between the two points of an edge if the distance of the point to that edge is smaller than a threshold. * Fixed both 3D and 2D code to utilize this. Possibly other places in blender where this scaling is done will have to be adjusted. * Changed vertex interpolation to use 2D interpolation, since it already did projection on plane and 2d calculations are faster. * Also added notifier on hard recalc when uvcalc_transfor_correction is used. Results in instant feedback on UV editor when edge sliding.
2013-01-07	add area_poly_v3_max() for use with area_poly_v3	Campbell Barton
