  1. reduce clipper offset miter limits from 3 to 2 in light of thinwall work

    Mike Sheldrake committed Jun 4, 2013
    Hopefully medial axis thinwall and thin gap work will allow us to
    avoid the tradeoffs involved in higher/lower miter limit values.
    3 gives some spikes, but merges gaps; 1 reduces spikes but leaves gaps
    Medial axis thinwall work should fill in/link those gaps.

  1. simplify polygons before generating medial axis

    Mike Sheldrake committed Jun 3, 2013
    Extremely close vertices resulting from safety_offset()s in
    _merge_loops() seemed to confuse Boost::Polygon::Voronoi.
    Probably not an upstream bug, but just an integer grid snap issue.

  1. have medial axis fragments go deeper into non-thin region

    for outer perimeter - otherwise they come up short and don't
    merge with the perimeter for cases like the "rake" in #281
  2. intermediate work

    mostly adjusting the left-right discriminating strategy to handle
    cases that come up in some of the models for user thinwall issues

  1. tuned to do completely centered thinwall path up to 2x width

    Mike Sheldrake committed May 26, 2013
    instead of following part contour between 1x and 2x width
    because the all-centered case avoids complexity better handled
    by future dynamic flow work

    New EdgeCollection, a fix for EdgeView->nex/prev auto generating

  2. Refining medial axis representation and handling

    Mike Sheldrake committed Apr 29, 2013
    Improved and moved some edge angle (theta and phi) calculations
    upstream to Boost::Geometry::Utils.
    EdgeView constructor now takes key=>value args.
    EdgeView->next/prev/twin, if not already defined, auto-generates
    EdgeView on underlying Edge.
    Simplified edge to point list conversion, and left-right
    Fixed offset edge point interpolation that used wrong endpoint
    on one end.

  1. Merge branch 'master' into thinwall-bpv

    Mike Sheldrake committed Apr 25, 2013
    Only significant conflict is change to first perimiter
    inset-outset cycle - making the inset the same as for
    other perimeters, and just reducing the following outset.
    This gives consistent behavior with regard to where
    polygons "turn around" when headed toward thin features,
    making the turn around happen at about 2x extrusion width
    for the outer perimeter, as it does for the inner perimiters.

  1. Avoid merging meshes when there is only one mesh to merge.

    beanz committed Apr 18, 2013
    When slicing yoda.stl it reduces peak memory usage by 5% and speeds up
    slicing by 13%.
    Further optimization using a simple proxy to implement the two methods
    (size/extends) needed on the merge meshes is also possible and
    undoubtedly worthwhile.
  2. Use binary search for get_layer_range.

    beanz committed Apr 18, 2013
    Gives a 13% speed up on Teethy_Tiki.stl (thing:49334) with default settings
    on my laptop.
    When $self->layers->[0]->slice_z == $min_z the returned $min_layer value is
    0 rather than the (incorrect?) -1 returned by the old code.
  3. Fix dependencies to require Math::Clipper 1.18.
