Quads: Beauty, Fixed, Fixed Alternate, Shortest Diagonal
Ngons: Beauty, Scanfill
* Shortest Diagonal is the default method in the modifier (popular
elsewhere), but beauty is the default in Ctrl+T).
* Remove the need for output slot and beauty operator to be called
after Clt+T
Patch with collaborations and reviewed by Campbell Barton
since enough bmesh operations can also take advantage of direct index lookups on verts/edges/faces.
developers note:
- EDBM_index_arrays_init/ensure/free -> BM_mesh_elem_table_ensure/init/free
- EDBM_vert/edge/face_at_index -> BM_vert/edge/face_at_index
- EDBM_uv_element_map_create/free -> BM_uv_element_map_create/free
- ED_uv_element_get -> BM_uv_element_get
changing the ot->name only, not the ot->idname
(to avoid breaking scripts)
The tool requires the selection to be fill previously,
the original name was confusing if we consider we have
"Fill" with the "Beauty" option.
Discussed with Bastien Montagne and Brecht van Lommel.
- use 4 weights for vertex customdata blending (was previously only using 2)
- option for simple blending, which blends locations using weights too and doesn't attempt to maintain the shape,
useful for flat surfaces or times when keeping the shape gives odd results.
cuts the mesh in half based on the cursor location and the viewport,
optionally supports filling the cut area (with uvs. vcols, etc),
and removing geometry on either side of the cut.
calls: bisect, duplicate, scale, flip, weld.
resolves report [#36475] Symmetrise does not keep uv/weight
also fixes issues with faces that cross the axis more then once.
Forward enum declaration is a bad idea, especially for C++ which requires
enum specification to dteermine which data type to use to store it.
Alternative would be to not use enum as an arument and pass it as int,
but actually would rather be strict on typing -- using explicit enum
as parameter type helps understanding the code and prevents possible
mistakes when using the function.
Update from a script I had in 2.4x, useful if you have mesh data which is _almost_ symmetrical,
there was no good way to automatically make the minor adjustments to make the mesh fully symmetrical.
Options for...
- symmetry-axis.
- blending between the +/- side.
- center mid verts.
Access from Mesh menu.
Was using edge-slide & remove-doubles but this was error prone since remove doubles could fail in some cases or find doubles where it shouldn't (with very small scale objects).
This gives more predictable behavior when the edges of a loop wouldnt slide (in that case they would just drag over to one of the sides with no user control)
and multiple edge loops work better too. eg:
