| | | | | | | | FloatUtil.EPSILON epsilon and no collinear test commit 5488665474cc7b88577cedfca6416784f0fda3ba Generalize *seg2segIntersection* w/ epsilon and doCollinear caused a big performance hit about 1/3 due to added doCollinear case and manual epsilon adding branches and having the method being longer - probably not 'hotspot'ed.

* Bug 1501: Apply intersection tests for non-convex shapes to reject new CCW ↵Sven Göthel2024-02-135-129/+369
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and non-circulcircle triangulation candidates in our Delaunay tessellator <https://jogamp.org/bugzilla//show_bug.cgi?id=1501#c6> The used Delaunay tessellation works well with (almost) convex shapes. In case e.g. a glyph gets to the extremes like 'M' in FreeMono or any other complex Chinese symbol - it may just simply happen that the new non-circumcircle triangle point crosses the inner (hope) or outer boundaries of the given polygon. Applying further constraint at Loop.cut() resolves most cases by rejecting the proposed CCW and non-circumcircle triangle candidate if its new two line-segments intersects with the original polygon. This results in mostly proper rendered Chinese fonts and also FreeMono is now readable - overal remaining bugs in Glyphs is low. +++ Of course, this intersection test is costly around >= O(log(n)*n) costs, practically adding a measured ~65% processing time. E.g. for FontView01 using FreeSerif.ttf - orig total took 1430.817638ms, per-glyph 0.2236ms, glyphs 6399 - fix total took 2377.337359ms, per-glyph 0.371517ms, glyphs 6399 Pure Glyph/Shape instantiation shows > 2x costs: 750 ms 100% convex (fake) 1875 ms 0% convex (fake) 1870 ms 13% convex 824/6399 +++ Hence it is desired to either (1) Manually mark a polygon non-convex to add described intersection test for accuracy. Also may be used to just drop the additional costs despite the lack of correctness. PROVIDED (2) Determine non-convex nature of a polygon with a and overall less expensive algorithm. If considerably cheaper, this could reduce O(log(n) * n) -> O(n) or even O(log n). Added convex/non-convex classification while ignoring off-curve points, but only ~13% of FreeSerif is pure convex, hence there is no benefit with this classification type. It might be desired to attempt other classes, i.e. being rendered in non-convex mode w/o intersection tests.

| | | | | | | | | | | new impl; Add isConvex*() to determine whether a polyline is convex I had problems using the previous line2line intersection methods in my (and my son's) C++ gfxbox2 project, e.g. freefall01. Hence I found a different solution, also using less operations: <https://jausoft.com/cgit/cs_class/gfxbox2.git/tree/include/pixel/pixel2f.hpp#n660> While adding intersection tests for our Delaunay (Bug 1501) .. I came across this issue again and hence swapped the implementation.

* Bug 1501: Graph Delaunay: Use default winding outer-boundary:=CCW and ↵Sven Göthel2024-02-125-45/+77
| | | | | | | | | | | inner-hole:=CW w/o using winding determination (might be incorrect) This simplifies our code further and it has been validated that our polygon shoelace-algo for area >= 0 ? CCW doesn't produce correct results with all curves. Hence rely on given winding depending on outer-boundary and inner-hole if CDTriangulator2D.FixedWindingRule == true (default and fixed). This also removes the more costly winding shoelace calculus, hence Outline ctor only sets dirtyWinding:=true w/o calculating the winding.
