Vector.angle_signed(other) for 2D vectors to get the clockwise angle between them. in BLI math its called - angle_signed_v2v2() shorthand for... atan2f((v1[1] * v2[0]) - (v1[0] * v2[1]), dot_v2v2(v1, v2)) also corrects compile error in last commit.
2012-03-13workaround [#30480] Knife tool flickerCampbell Barton
the problem was numeric precision when in ortho mode the start/end points for the view vector would be 2000 apart which caused trouble for the intersection test.

quads.
2012-03-13fix [#30529] BMesh: Wrong Indizes of FacesCampbell Barton
problem was bow-tie quads would add opposite normals together and result in zero vector which was used for projection. Now is_quad_convex_v3() checks if quad contains 2 faces which point away from eachother when split by either direction. Theres another fix for this bug which can be done since creating the face can use existing edges in the example given so it wont have to guess which order of verts to use.

2011-12-15vertex group changes,Campbell Barton
use more api functions more (some vertex group editing functions were copied about), also make some functions int oapi calls. - remove defgroup_find_index(), use BLI_findlink instead since they both work the same way. - move static function getNearestPointOnPlane() to BLI_math api function closest_to_plane_v3() - ED_vgroup_give_parray() added option to return an array where unselected verts are NULL (simplifies code & works for lattice when it didn't before). - more consistant error checking of ob->actdef.

2011-06-06Bake from multires meshSergey Sharybin
======================= Added option to baked named "Bake From Multires" which is avaliable for normals baking and displacement baking. If this option is enabled, then no additional hi-res meshes and render structures would be created . This saves plenty of memory and meshes with millions of faces could be successfully baked in few minutes. Baking happens from highest level against viewport subdivision level, so workflow is following: - Set viewport level to level at which texture would be applied during final rendering. - Choose Displacement/Normals baking. - Enable "Bake From Multires" option. - You're ready to bake. Displacement baker had aditional option named "Low Resolution Mesh". This option is used to set if you want texture for realtime (games) usage. Internally it does the following: - If it's disabled, displacement is calculated from subdivided viewport level, so texture looks "smooth" (it's how default baked works). - If it's enabled, dispalcement is calculated against unsubdivided viewport levels. This leads to "scales". This isn;t useful for offline renders much, but very useful for creating game textures. Special thanks to Morten Mikkelsen (aka sparky) for all mathematics and other work he've done fr this patch!
