- 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.
- Edge rotate would leave verts selected, this would give problems because those selections would leave edges that would try to rotate when run again. now de-select old verts on edge rotate.
- Rotating into hidden verts gave odd results, now make sure hidden state is ok.
- BMO_slot_buffer_hflag_disable / BMO_slot_buffer_hflag_enable now have flushing for the hide flag too.
- tessface vertex color had the wrong sized array passing to rna_iterator_array_begin
- re-calculating tessface's would clear them if they were already created (own mistake)
- ED_mesh_color_add initialized tessface vertex colors from the loop color array
also made rna's mesh.tessface_vertex_colors.new() work like tessface_uv_textures.new()
where layers can be added as long as polygons are not present.
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.
This is in preparation for bug fixing and cleanup related to tracking
of bmface and is_space state variables. And makes it more likely
to avoid bugs in future where some part of state is copied but not all.
Sometimes split would fail to make a face - make sure it doesn't
crash if that happens.
Chain finding code for holes would sometimes go back to same
vertex on the face, which causes problems, so fixe that.
Also, disallowed a cut that starts at a vertex or edge and
cycles back to that same point in a face - this would make
a face with a repeated vertex, which may not be handled by
the rest of the system properly.
this fixes but [#30461] where the same vertex was added to some faces twice.
Previous code rebuilt all faces around the split edges, replace this with much simpler code that uses existing bmesh API for splitting.
This also gives a performance boost to the modifier (over 30x faster in the bug-report file).
This corresponds to the more usual convention.
There was no key connected to Cancel, and we already
have Return, Numpad-Return, and Right-click for confirm.
- access to a meshs editmesh before the pointer was checked to be a mesh.
- uninitialized memory use in transform (not a problem practically but nice to quiet the error in valgrind).
Knifetool accumulates a bunch of proposed cuts and when the user
confirms, it makes them all. The old code did this by using scanfill
to triangulate the cutting edges in their faces, and then merging
triangles where possible. This sometimes ended up with strange
lost faces, and also made it so that when holes were cut, the
surrounding face ended up totally triangulated. But 29908 was
an example of a lost face.
This new code directly finds chains of cutting edges that go from
one side of a face to the other and using BM_edge_split_n to make
the cuts. Holes are handled by finding two good places where
the hole can be connected to the containing face (using two
because I think some other code in bmesh assumes that there are
no edges that appear twice in a face).
The old code is still there with #if SCANFILL_CUTS, so can easily revert
if this proves to be a bad idea.
Also, a small fix to previously added BM_split_n (forgot to
copy face attributes to new face).
"This patch adds "Not Equal To" to the list of options for selecting faces based on the number of vertices. While the equivalent can indeed be achieved by using "Equal To" and invert selection, having this option allows for a smoother work-flow when adjusting the number of vertices to be compared."
when the source and destination vectors were the same pointer, the X value would get overwritten.
now the rip tool uses the best side to grab as in trunk.
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.
mesh.calc_normals() wasnt calculating vertex normals (only face normals),
now only calculate vertex normals.
added a define incase we want to have poly normals back again.
