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.
