Tomasz Wlostowski 482767a850 libs/kimath: implement indexable subshape support for SHAPE_COMPOUND and SHAPE_POLY_SET 2020-09-27 16:45:46 +02:00
Seth Hillbrand 08bf5f4b4e ADDED: 45° snapping for rectangles aka Squares
The snap obeys only the Ctrl key and not the global preference setting
for drawsegments because rectangles are _always_ on H/V lines when drawn

Jeff Young e2bc7557cc Clean up arc/circle polygonization.
1) For a while now we've been using a calculated seg count from a given
maxError, and a correction factor to push the radius out so that all
the error is outside the arc/circle.  However, the second calculation
(which pre-dates the first) is pretty much just the inverse of the first
(and yields nothing more than maxError back). This is particularly
sub-optimal given the cost of trig functions.

2) There are a lot of old optimizations to reduce segcounts in certain
situations, someting that our error-based calculation compensates for
 anyway.  (Smaller radii need fewer segments to meet the maxError
condition.) But perhaps more importantly we now surface maxError in the
UI and we don't really want to call it "Max deviation except when it's
not".

3) We were also clamping the segCount twice: once in the calculation
routine and once in most of it's callers.  Furthermore, the caller
clamping was inconsistent (both in being done and in the clamping
value). We now clamp only in the calculation routine.

4) There's no reason to use the correction factors in the 3Dviewer;
it's just a visualization and whether the polygonization error is
inside or outside the shape isn't really material.

5) The arc-correction-disabling stuff (used for solder mask layer) was
somewhat fragile in that it depended on the caller to turn it back on
afterwards.  It's now only exposed as a RAII object which  automatically
cleans up when it goes out of scope.

6) There were also bugs in a couple of the polygonization routines where
we'd accumulate round-off error in adding up the segments and end up with
an overly long last segment (which of course would voilate the error
max). This was the cause of the linked bug and also some issues with vias
that we had fudged in the past with extra clearance.

Seth Hillbrand 08d4e91f3b Change partitions to fixed size
Partititioning small polygons causes excessive partitions when we use a
fixed number of cells per side.  Partitioning by size keeps the
partition count limited and speeds the calculations.

Also adds an option to not partition the grid for elements (like 3d
raytracing) that do not need it.

Seth Hillbrand afc94fdec3 PNS: Be better about handling multiple layers
Rather than adding pads/vias multiple times for each layer, we introduce
the "alternate shape" idiom to PNS that allows us to optionally place
the collision constraint on the hole instead of the pad for those
vias/pads that have inner layers removed.

Jeff Young eb1ff80d57 SHAPE collision fixes.
1) An actual distance of 0 is still a collision, even if the allowed
distance is 0.
2) Be consitent about edges and interiors.  Everyone expect the edge
of a RECT to be part of the RECT; same with a CIRCLE.  SHAPE_POLY_SET
shouldn't be any different.  (And SHAPE_LINE_CHAIN was a split-
personality with the edge considered part of it for Collide() but not
for PointInside()).

Jeff Young d01b29ab37 Cleanup pad geometry handling.
There were a lot of plotters, exporters, etc. that were rolling their
own implementations.

This also introduces a lazily-built set of SHAPE objects for doing
collision detection and some forms of rendering (and later DRC).

jean-pierre charras 3e247a70d5 Gerber plot: new algo to generate solder mask layers with non 0 min thickness mask
Previously, all overlapping polygons (pads and min thickness areas to remove) were
merged.
Drawback: pads attributes are lost. In Gerber this is annoying.
Now the pads are plot as flashed or Regions items, and min thickness areas are added
but shapes are not merged and keep their attributes.

Seth Hillbrand c4fff95078 PNS: Detect collisions including newline width
The new line collision search uses BBox() to check for colliding
objects.  BBox in the SHAPE_LINE_CHAIN did not include width as the
chains were assumed to be zero-width.  This is not the case for
PNS::LINE elements.

We mostly don't notice this because DRC checks for SEGMENT collisions
but it becomes obvious/annoying when we cannot place a track for unknown
reasons and the snap-back doesn't take line width into account.
