Tool for creating polygons, exact usage may change based on feedback.
LMB to add faces at boundaries (tris from edges, quads from verts).
- Ctrl splits edges
- Alt to dissolve edges/verts.
Works well with vertex snap & auto-merge.
This uses selection hover but isn't intended to introduce more widely
pre-selection highlighting, at least it will be restricted to this tool.
|
|
Support applying decimate to the mesh selection.
|
|
|
|
This uses selection history to select the next vert/edge/face based on surrounding topology.
Select previous just removes the last selected element.
Uses key-bindings: Ctrl-Shift +/-
|
|
Taken from original bmesh-branch but doesn't give useful results
(misses selection flushing).
|
|
Works much the same as intersect operator,
expose as a new operator since for users its quite different.
Access from face menu.
Internally, this adds boolean args to BM_mesh_intersect function.
|
|
Ability to quickly add 2x edge loops on either side of selected loops.
|
|
|
|
So that they match all other op names around - and sensible logic as well.
|
|
There are several ways to end up with an object with skin modifier, but no
skin data on the geometry. So we need an operator to add it by hands.
Also tweaked a bit UI of this modifier.

Our current keymap doesn't give us enough room to make such changes in
the event system. To fix small issues caused by this, we would need to do
drastic changes in Blender's keymaps and internal handling. It was worth
a try, but it didn't work.
I can write down a more descriptive statement in a few days, but for now
I need a break of this stuff.

extruding
More practical description of the bug: extruding with ctrl to use
snapping and confirming the action added another extrusion to the mouse
position.
This was caused from the second event that is now sent if a key release
happens within the click timeout. It triggers the "Extrude to Cursor"
operator since it is called by CTRL+LMB wich is exactly the event that
is sent in this case.
I'm not totally happy with this workaround since it changes the Confirm/
Abort event for all transformation actions to key release which *might*
result in more conflicts (fingers crossed this isn't the case). If this
happens we might need to write some special transformation handling for
extrusion.
This is an example of the difficulties we get from loading too much
functions on the same keys - we need to be careful with that!

Design task: T42339
Differential Revision: D840
Initial implementation proposal: T41867
Short description:
With this we can distinguish between holding and tabbing a key. Useful
is this if we want to assign to operators to a single shortcut. If two
operators are assigned to one shortcut, we call this a sticky key.
More info is accessible through the design task and the diff.
A few people that were involved with this:
* Sean Olson for stressing me with this burden ;) - It is his enthusiasm
that pushed me forward to get this done
* Campbell and Antony for the code and design review
* Ton for the design review
* All the other people that gave feedback on the patch and helped to
make this possible
A big "Thank You" for you all!

Could connect a pair of verts previously,
now connect all vertices along the path, running a second time closes the loop.
Can also be used for without faces to connect edges between selected points.

This is the core code for it, tools (datatransfer and modifier) will come in next commits).
RNA api is already there, though.
See the code for details, but basically, we define, for each 'smooth fan'
(which is a set of adjacent loops around a same vertex that are smooth, i.e. have a single same normal),
a 'loop normal space' (or lnor space), using auto-computed normal and relevant edges, and store
custom normal as two angular factors inside that space. This allows to have custom normals
'following' deformations of the geometry, and to only save two shorts per loop in new clnor CDLayer.
Normal manipulation (editing, mixing, interpolating, etc.) shall always happen with plain 3D vectors normals,
and be converted back into storage format at the end.
Clnor computation has also been threaded (at least for Mesh case, not for BMesh), since the process can
be rather heavy with high poly meshes.
Also, bumping subversion, and fix mess in 2.70 versioning code.

Select operator that takes multiple selected face regions and
selects any number of matching regions (when they have distinguishing features to isolate them).
UI access next.
|

Modeling tool to cut intersections into geometry (like boolean, without calculating inside/outside).
Faces are split along intersections, leaving new edges selected.
Access from Face menu.

This can be used in a similar way to the knife tool, but the edges are manually setup first.
|
|
|
|
Helps to easily add details to existing edges.
Similar to the rip tool it depends on cursor location to choose the edge to extend along.
|
|
Opted to keep includes if they are used indirectly (even if removing is possible).

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

optionally supports filling the cut area (with uvs. vcols, etc),
and removing geometry on either side of the cut.

- fix missing null pointer check from own recent changes.
- add asserts if BLI path functions are given wrong id's

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:
- http://www.graphicall.org/ftp/ideasman42/edge_loop_del_update.png
|
|
- Ctrl+RMB only worked for edges & faces
- Menu item 'Select Shortest Path' only worked for vertices.
Now Ctrl+RMB works for vertices and the menu item works for verts/edges/faces (depending on the current selection).
|
|
also added the underlying subdivision as a standalone operator in the edge menu, named: subdivide edge-ring.

This uses 2 edge loops and fills them with a grid, taking into account curvature of surrounding edges.
