- memset(..., -1) is used incorrectly even though it worked: MOD_solidify.c - thanks Halley from IRC for noticing this. use fill_vn_i() instead.
- quiet warnings in editmesh_slide.c
- cleanup comments in bmesh and some other minor comment additions.
added access to deform weights, access to weights acts like a python dict so you can do...
print(group in dvert)
dvert[group] = 0.5
print(dvert[group])
del dvert[group]
print(dvert.items())
- add examples for custom-data access
- group BMesh types logically in docs
- added missing docstrings
needed to add grouping functionality to sphinx for this.
use different types for bm.verts.layers, bm.faces.layers, otherwise the layers look to have customdata type that isnt compatible, UV's on edges for eg.
old mesh MCol 'r' was blue, 'b' was red, but theres no reason to keep this for bmesh with MLoopCol.
Loading old files works, saving legacy format works too.
What wont work is loading a file after this revision and loading it in an older revision since the bmesh merge.
(it wont crash but the blue and red will be swapped on vertex color layers).
split up BMElemSeq into BMVertSeq, BMEdgeSeq, BMFaceSeq and BMLoopSeq
Was becoming cumbersome since each needed their own new() function, and other methods only worked for some of these types.
Added BMesh.loops - since you cant iterate over loops this is for customdata access only.
Wrap customdata, so far you can access the data layers in a pythonic way but not manipulate the customdata yet.
provides dictionary like access to customdata layers, eg:
texpoly = bm.faces.tex["UVMap"]
print(bm.verts.shape.keys()) # un-intended pun, keys() works on all layers.
print("MyInt" in bm.edges.int) # __contains__
layer = bm.faces.get("CheckForLayer")
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.
- moved mesh conversion functions into their own file.
bmesh py api:
- can now create a new empty bmesh without first creating mesh data.
- added function to copy bmesh data back to a mesh.
- bmesh.from_mesh() can now get a mesh which isnt in editmode.
* C: BM_vert_separate(...)
* py: bmesh.utils.vert_separate(vert, edges)
This splits off regions around the vertex, splitting on connected edges passed in a sequence.
also made minor changes
- rename python api functions _rip to _separate
- fixed bmesh iterator being iterable its self (some parts of python expect this)
- fix memory leak in bmesh python api.
Now create the rotate edge in advance and copy its customdata (before joining the faces).
This commit also fixes an annoyance where tryangulating faces could create duplicate edges.
