other selection operators. Instead of having only a single "extend"
option which causes the selection to toggle, there are now
three options:
- extend: adds to selection
- deselect: removes from selection
- toggle: toggles the selection
The default keymap is adjusted to have identical behavior as before,
using these new options, so end-users shouldn't experience any
difference.
- Rename 'mesh.select_nth' operator menu item 'Every N Number of Verts' to 'Checker Deselect',
since its not just de-selecting verts (works on edges and faces too) and the term 'checker' gives a better description of the result.
- Rename 'mesh.select_by_number_vertices' to 'mesh.select_face_by_sides', since this is a face selection tool, which wasnt obvious from its name.
also remove dissolve by type menu since the option has been removed from the operator and was giving an error.
* Bullet's convex hull implementation is significantly more robust
than the one I implemented, as well as being faster.
* This fixes bug [#32864] "Convex Hull fails in some cases."
projects.blender.org/tracker/?func=detail&aid=32864&group_id=9&atid=498
That bug, and others like it, relate to the poor handling of
co-planar surfaces in the input. Pretty much any model that is
simple-subdivided a few times gave very bad results before, Bullet's
implementation handles this much better.
* In order to ensure a smooth transition, the Bullet output is
translated into the existing HullTriangle hash structure. This makes
it easy to ensure that the existing slot output stays the same; the
interactions between the slots are somewhat complicated, detangling
is a TODO.

* The symmetrize operation makes the input mesh elements symmetrical,
but unlike mirroring it only copies in one direction. The edges and
faces that cross the plane of symmetry are split as needed to
enforce symmetry.
* The symmetrize operator can be controlled with the "direction"
property, which combines the choices of symmetry plane and
positive-negative/negative-positive. The enum for this is
BMO_SymmDirection.
* Added menu items in the top-level Mesh menu and the WKEY specials
menu.

Alt+V will fill the area inbetween the ripped faces - a bit like extrude.
faces are flipped to match existing geometry and customdata (uv, vcols etc) is copied from surrounding geometry too.
updating data was only being done on the active object but sticly was being calculated for the selection.
split this into 2 operators, one that works on the selection and another that operates on the active object - so we can have a button in the mesh panels that calculates sticky.
also note that there was no way to calculate sticky from the UI - perhaps this feature should die a quiet death?
anyway - it works better then it used to for now.
currently can remove sticky/mask/skin vertex layers.
regarding the skin layer - while adding and removing the modifier normally works fine, its not 100% reliable since the mesh may be linked into another scene, or be a linked duplicate and the object with the modifier deleted.
This commit adds some first building blocks for the two operators to work modally based on mouse input. To make their function easier, two hotkeys are introduced, Ctrl+B for bevel and I for inset.
TODO:
After discussion with Campbell, we would like to add scale-style line indicators for the operators. This is already done for transform operators but a new interface for mesh operations may have to be written using pieces from that code since, strictly speaking bevel and inset are not exactly "transform" operators.
Also, a better input method for inset is needed and more options exposed. The method implemented right now uses mouse move for thickness and ctrl-mouse move for depth. These are calculated using the distance of the selection center in screen space and the mouse position. While that may work and prevents abrupt changes in values when switching from thickness tweak mode to depth tweak mode, it limits the magnitude of values that can be put into the tool especially in small or large scale.
Alternatives until a better method is written include:
* use relative offset (works but may give strange results)
* tweak manually after the operation.
Now only one operator. Same options for vertices, edges and faces (so adds edges sorting, and some options to vertices sorting).
Face sorting should behave as previously. However, XSortVerts won’t pack anymore selected vertices at the begining of the vert array (as it used to), if you want such behavior you’ll have to first run SortElements with Selected action.
Also added bug ref I forgot in r46354 (armature.c).
- makes wireframe from faces.
- options similar to inset (even offset, relative scale)
- copies face settings and loops (uvs, vcolors)
- optionally replaces the existing geometry.
from user freedback it seems there are 2 use cases, both valid.
* Select geometry and cut the selection in half (as 2.4x worked)
* Point-to-point define the faces to cut, dont cut through everything (only cut what you see).
With the second, since you are already selecting the edges to cut and snapping to them. only cutting the selecting is limiting/annoying.
Modifying these options while the knife tool runs doesn't work well, so expose under 2 keys, K, Shift-K.
- Even option (like solidify even option)
- Relative option (insets based on lengths of surrounding edges)
TODO: merge tares when 2+ face corners meet but don't form a contiguous region.
* made bmesh_structure.h function names more consistant.
* remove unused code in bmesh_structure.c
* removed 'Edge Flip' operator (missing from bmesh but looked into trunk feature and dont think its worth keeping).
* tagged some BMESH_TODO's
This is a kind of simplification/cleanup tool which joins adjacent faces and edges based on the angle.
I've written this as an exercise (since I havnt written a bmesh operator before), and because quite a few users were asking for the dissolve operator to be extended, but I think this kind of functionality needs its own operator.
access from specials menu and mesh menu.
notes
* this exposed a bug in angle_v3v3v3(). will merge fix into trunk after release.
* added utility function BM_vert_edge_angle(), to get the angle between 2 connecting edges of a vert.
