This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Will document the new options in release notes, then in manual.
Still a bit of work to do on the bulging shape that appears
on cube corners if using arc inner miters, but will do that later.
Also need to do something smarter in clamp overlap.
Harden normals causes normal splitting, which will not give the
appearance expected due to autosmooth unless some edges are sharpened,
so this change fixes that. Also bevel tool will turn on autosmooth
if not already on if hardening normals.
Move the bevel hardening code all into bmesh_bevel.c.
Based on user feedback, rewrote the bevel hardening algorithm
to be more what users want.
Based on user feedback, changed the UI, removing some
not-useful options. Now hardening normals while beveling
is enabled by a simple checkbox.
Now setting face strength gives options for which faces
get their face strength set.
These changes are necessary. Need to mark vertices of edges passed
in geom; also the normals.out slot has a custom element type, not
ELEM, so need to prevent attempt by python code to convert it to
an elem. But this leaves a memory leak. I will rework code to not
use normals.out slot at all, but that's a bigger fix.
Now there is a crash in a different place (GPU code). Think that if
using Op on its own (instead of from edbm_bevel_calc, there needs to
be a dependency graph update and maybe more?
faces.
This was requested by script writers. Especially needed if beveling
wire edges with vertex_only.
Should be backward compatible as just adds two new keys to returned
dict in python ('edges' and 'verts').
Current behavior of bevel is to 'loop slide' along unbeveled edges
when possible, but this produces uneven bevel widths sometimes,
so this option lets user choose between having the loop slide effect
or having more even bevel widths. Trying it out with default being
'no loop slide', so different from current behavior. May reverse this
choice later, depending on user reactions.
Now the bevel tool, modifier, and internal operator have a material
slot # parameter that the user can set. If left at default of -1,
behavior is as current -- bevel face material is taken from the
closest original face (this may be ambiguous). If material slot
is >= 0, it gives the material slot index number for the material
to use.
Parameter controls concavity / convexity.
<.25 means: concave inward
.25 means: straight slanted
>.25 means: concave outward
.5 means: circular (the default)
1 means: straight along original sides
For now, there is a hard lower limit of .15
because more work is needed to get decent
results in the range below that.
The profile is actually a superellipse, and the
parameter is 1/4 of the exponent in the implicit equation
for a superellipse, except at the extreme values of 0 and 1.
Now there is an 'Offset Type' dropdown on tool
shelf with types:
Offset - current method, offset of new edge
from old along sliding face
Width - width of new bevel face (if segments=1)
Depth - amount a chamfering plane moves down
from original edge
Percent - percent of way sliding edges move
along their adjacent edges
The different options mainly are useful when
beveling more than one edge at once.
Leaving as a TODO to put these in the modifier,
as doing that has more permanent effects so
want to let users shake out problems with this
first.
This is a quick fix that perhaps overestimates the point
of first geometry collision, but at least for now it should
allow models that used the old modifier and a too-big
bevel amount to not look awful.
The correct solution to this problem is much more involved
and I'll get to it later.
Now modifier takes a segments parameter.
Bevel edge weights will multiply the overall amount.
For vertex-only, you can give a vertex group name,
and the weights in that will multiply the overall amount.
- the resulting selection is now correct
internal details
- bev_rebuild_polygon() now only rebuilds polygons that are attached to a bevel vertex (was rebuilding ALL).
... need to take care we don't leave faces pointing to removed geometry, so far this works fine.
- bev_rebuild_polygon() uses stack memory for <32 size ngons to reduce allocs.
- skip hash lookup when removing bevel verts (use tag instead).
also some other changes - no need to check the new loops face is larger and no longer split up the ngon more times then there are subdivisions in the face strip (now ngons will remain on both sides).
now USE_ALTERNATE_ADJ works, giving more stable corners that don't flicker and glitch out as the offset changes.
The shape is not a circle though and doesnt look quite as nice as the existing method.
