* Bug 1501: Refine convex == !complex: Use 'complex' term, have env-property ↵Sven Göthel2024-02-141-24/+31
| | | | | | toggle OutlineShape's isComplex() for visibility We may use complex for other criteria than !convex, i.e. self-intersecting etc.
* Bug 1501: Apply intersection tests for non-convex shapes to reject new CCW ↵Sven Göthel2024-02-131-13/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Bug 1501: Graph Delaunay: Use default winding outer-boundary:=CCW and ↵Sven Göthel2024-02-121-4/+4
| | | | | | | | | | | 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 1452 - Decouple math functionality to 'com.jogamp.math' to be toolkit ↵Sven Gothel2023-09-2010-2247/+10
| | | | | | | | | | | | | | | | | | | | agnostic (PMVMatrix, Matrix4f, Vec4f, ..) Math functionality (PMVMatrix, Matrix4f, Vec4f, ..) - shall be used toolkit agnostic, e.g. independent from OpenGL - shall be reused within our upcoming Vulkan implementation - may also move outside of JOGL, i.e. GlueGen or within its own package to be reused for other purposed. The 'com.jogamp.opengl.util.PMVMatrix' currently also used to feed in GLUniformData via the toolkit agnostic SyncAction and SyncBuffer shall also be split to a toolkit agnostic variant. An OpenGL PMVMatrix specialization implementing GLMatrixFunc can still exist, being derived from the toolkit agnostic base implementation. +++ Initial commit .. compile clean, passing most unit tests.

* Graph + GraphUI: Consolidate Vertex: Drop SVertex and factory, use Vec[234]f ↵Sven Gothel2023-04-185-277/+174
| | | | | | | | | | | instead of float[] and remove unused VectorUtil methods After Matrix4f consolidation and proving same or better performance on non array types, this enhances code readability, simplifies API, reduces bugs and may improve performance.

* Math: Complete Matrix4f w/ Vec[234]f and adopt it throughout Quaternion, ↵Sven Gothel2023-04-051-11/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | Ray, AABBox, Frustum, Stereo*, ... adding hook to PMVMatrix Motivation was to simplify matrix + vector math usage, ease review and avoid usage bugs. Matrix4f implementation uses dedicated float fields instead of an array. Performance didn't increase much, as JVM >= 11(?) has some optimizations to drop the array bounds check. AMD64 + OpenJDK17 - Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest) - Matrix4f.mul(b) roughly ~3% slower than FloatUtil.multMatrix(a, b, dest) - FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all - Matrix4f.invert(..) roughly ~3% slower than FloatUtil.invertMatrix(..) RaspberryPi 4b aarch64 + OpenJDK17 - Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest) - Matrix4f.mul(b) roughly ~20% slower than FloatUtil.multMatrix(a, b) - FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all - Matrix4f.invert(..) roughly ~4% slower than FloatUtil.invertMatrix(..) Conclusion - Matrix4f.mul(b) needs to be revised (esp for aarch64) - Matrix4f.invert(..) should also not be slower ..

* Graph: Fix Loop.initFromPolyline()'s Winding determination, document Winding ↵Sven Gothel2023-02-171-2/+81
| | | | | | | | | | | | | | | | | | | | | | | rules for OutlineShape and add get/setWinding in Outline Loop.initFromPolyline()'s Winding determination used a 3-point triangle-area method, which is insufficent for complex shapes like serif 'g' or 'æ'. Solved by using the whole area over the Outline shape. Note: Loop.initFromPolyline()'s Winding determination is used to convert the inner shape or holes to CW only. Therefor the outter bondary shapes must be CCW. This details has been documented within OutlineShape, anchor 'windingrules'. Since the conversion of 'CCW -> CW' for inner shapes or holes is covered, a safe user path would be to completely create CCW shapes. However, this has not been hardcoded and is left to the user. Impact: Fixes rendering serif 'g' or 'æ'. The enhanced unit test TestTextRendererNEWT01 produces snapshots for all fonts within FontSet01. While it shows proper rendering of the single Glyphs it exposes another Region/Curve Renderer bug, i.e. sort-of a Region overflow crossing over from the box-end to the start.

* Bug 802: Graph TextRenderer Performance Part-1 (incomplete, rendering artifacts)Sven Gothel2014-02-244-31/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Strategy Change: - Font.Glyph itself holds it's OutlineShape with it's default scaling. Triangulation is done only once per glyph! - A CharSequence produces a Region by translating and scaling each Glyphs's OutlineShape. This removes the need for re-triangulate - see above. See: TextRendererUtil - The indices of re-added Triangles are offset to the new vertices (FIXME, seems not be be accurate yet). - OutlineShape's vertices and triangles are reused if 'clean'. - Simplified code - Reduced copies API Changes: - OutlineShape, Region, ...: See above - Removed TextRenderer, GlyphShape and GlyphString: Redundant - Added TextRendererUtil to produce the Region from CharSequence Result: - Over 600 fps while changing text for each frame. Previously only ~60fps max. TODO: - Region shall not hold the triangles itself, but the indices instead. This will remove the need to swizzle w/ vertices in the Region Renderer impl and easies reusage of OutlineShapes.
