* Bug 1489: Lock-Free Double-Buffered 'renderedShapes' causes data-race ↵Sven Göthel2024-02-179-87/+143
| | | | | | | | | | | | | | | between rendering & input-edt, use synchronized tripple-buffering Tripple-buffering _almost_ produces zero data-race collisions, however .. it still does rarely -> hence synchronize on the used ArrayList<>. This adds a minimal chance for blocking the input-EDT, but gives correct code & results. Double-buffered 'renderedShapes' was introduced to resolve Bug 1489 in commit 5f9fb7159fa33bc979e5050d384b6939658049bd This solution is tested by passing '-swapInterval 0' via CommandlineOptions for FontView01, UIMediaGrid01 .., i.e. rendering faster than picking and hence provoking the data-race condition.

* Bug 1501: Apply intersection tests for non-convex shapes to reject new CCW ↵Sven Göthel2024-02-136-134/+384
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | 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.

* Bug 1498: GraphUI: Fix Picking Traversal throughout Groups in Z-Descending ↵Sven Göthel2024-02-054-197/+246
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Order, testing Children and fallback to Group if positive Picking algo in Z-Ascending order worked only by chance, as it picked up any bottom node. +++ Proper algo is in Z-Descending order to block occluded (child) nodes: for-all s : shapes p1 = testPicking(s) if ( s is Container ) { p2 = testPicking(s.childs) if( null != p2 ) { p1 = p2; // override w/ child prio } } return p1 } Further, testPicking(shape) shall only return a positive shape, if the event dispatching check (mouse-over, click, ..) signals end-of-traversal - as originally intended. Overall philosophy is to pick the 'deepest' child of a group if responding, otherwise the next higher interactive group.
* Bug 1498: Change Top-Level Widget Mode: Register a top-level Group in Scene, ↵Sven Göthel2024-02-056-57/+109
| | | | | | | | | | | | | | | | | | | | | | | where its zOffset gets adjusted when activated.. .. instead of having a non-working complicated callback orgy setup. This also takes away the getAdjustedZ() overloading burden (or better uglyness) etc. Hence Group's setWidgetMode(boolean) became: - enableTopLevelWidget(Scene) - disableTopLevelWidget() The forwardActivation listener is still applied to all children as well as isActive() is also still overloaded for same required behavior. However, none of the children is set in 'widget mode' as well as the Group is simply added to (or removed from) the Scene's top-level Group list - the holder. Scene's setActiveShape(Shape) and releaseActiveShape() handle the top-level Group if affected, i.e. adding or zero'ing its ZOffset.
