- 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.
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count
* 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
Freestyle edge/face marks were ported to BMesh.
Conflicts resolved:
source/blender/editors/mesh/editface.c
source/blender/editors/space_view3d/drawobject.c
source/blender/makesdna/DNA_meshdata_types.h
source/blender/blenkernel/intern/editderivedmesh.c
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.
`_set` suffix was used in two ways (confusing)
* to set a flag to be enabled.
* to set a value passed as an argument.
now use enable/disable rather then set/clear for functions which change flags.
also remove BME_weld.c, the file didnt contain much code and the current extrude works well
- 2 new navmesh operators, reset and clear navmesh data.
- rename operators to be more consistent with existing names.
- some minor edits to draw function, was getting the custom data for every index when it already had the array.
New "face marks" and "edge marks" have been introduced in mesh data
blocks. In the edit mode of a mesh object, face marks can be put
to selected faces by choosing Mesh >> Faces >> Mark Freestyle Face
from the menu of a 3D View window or Ctrl-F >> Mark Freestyle Face
from the context menu. Similarly, edge marks can be put to selected
edges by Mesh >> Edges >> Mark Freestyle Edge or Ctrl-E >> Mark
Freestyle Edge. These marks should work fine with the Subdivision
surface modifier.
Moreover, two new conditions for feature edge selection have been
added to the Parameter Editor mode as described below:
1. The Selection by Edge Types option has now the new Edge Mark type,
which can be used to (de)select feature edges having edge marks.
This option can be used to add to (or remove from) the view map
arbitrary edges of mesh objects.
2. Selection by Face Marks option has been newly introduced, in which
face marks are used for feature edge selection in two ways. One
option is called "One Face" which is to (de)select feature edges if
one of faces on the left and right of each feature edge has a face
mark. The other option is "Both Faces" to (de)select feature edges
if both faces on the left and right have a face mark.
