* VectorUtil: Add experimental isSelfIntersecting1() with O(n*n) complexitySven Göthel2024-02-141-0/+69
| | | | This doesn't bring reliable results for Graph and also is pretty expensive.

| | | | | | | | 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 Göthel2024-02-133-26/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Göthel2024-02-123-20/+55
| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (PGS ..) via FFMPEGFMediaPlayer/FFmpeg FFMPEGFMediaPlayer related changes: - Add libswscale (6th FFmpeg lib used) for sws_getCachedContext(), sws_scale() and sws_freeContext(), used natively to convert the palette'ed bitmap into RGBA colorspace -> GL texture - Handling AVSubtitleRect.type SUBTITLE_BITMAP -- only handled if libswscale is available -- config/adjust texture object -- sws_scale palette'ed bitmap to texture -- intermediate memory is cached, may be resized and free'ed at destroy -- texture objects are managed and passed from GLMediaPlayerImpl, as they are also forwarded to player client via SubBitmapEvent - Passing the AVCodecID to GLMediaPlayerImpl, converted to our CodecID enum. - Unifying creation and opening of AVCodecContext with 'createOpenedAVCodecContext(..)' +++ SubtitleEvent* - SubTextEvent now also handles ASS.Dialogue (FFmpeg 4) besides ASS.Event (FFmpeg 5, 6, ..). +++ GLMediaPlayerImpl - Added ringbuffer subTexFree, managing Texture for bitmap'ed subtitles -- Uses 1 bitmap-subtitle Texture per used textureCount in cache, as one bitmap-subtile can be displayed per frame. Could be potentially reduced to just 2 .. but resources used are relatively low here. - Validating subTexFree + videoFramesFree usage, use blocking get/put ringbuffer due to utilization from different threads. - Receives subtitle content from native getNextPacket0() via callback, creates SubtitleEvent instance and passes it to a SubtitleEventListener - if exists. (See MediaButton example) -- SubBitmapEvent also gets its special SubBitmapEvent.TextureOwner to handle client releasing the event and allowing us to put back the Texture resource to 'subTexFree'. This passing through of the Texture object is probably a weakness of this lifecycle and requires the client to ensure SubtitleEvent.release() gets called. See MediaButton example! - Exposing CodecID, allowing clients like MediaButton to handle SubtitleEvent content according to codec

* Bug 1490 - GraphUI Group: Resolve Performance Issues with Shape Mv Transform ↵Sven Göthel2024-01-221-0/+2
| | | | | | | | | | | | | | | | | | | | -> PMVMatrix4f Shape.setTransformMv() is called for each renderer frame and for each shape, involving 6 Matrix4f.mul() and set*() operations. Since mutation of shape's position, rotation or scale is less frequent than rendering one frame (for all shapes), it is more efficient to maintain a local Matrix4f and update it on such single mutations. Rendering then only needs to perform one Matrix4f.mul() operation using this internal matrix. +++ Also changes name from setTransformMv(PMVMatrix4f) to applyMatToMv(PMVMatrix4f), as its name might be misleading.
* Bug 1488 - Graph RegionRenderer Shader Mapping: Revert to IntObjectHashMap ↵Sven Göthel2024-01-221-64/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and throw exception on shaderKey collision Commit 6363ae5fb6975a6f2e7c1093ce81f25b699e3e61 changed RegionRenderer.useShaderProgram()'s shader mapping using a new ShaderKey instance. Such ShaderKey instance is created every time @ RegionRenderer.useShaderProgram() to retrieve the ShaderProgram from the HashMap<ShaderKey, Shader Program>. While this is most correct, creating the ShaderKey instance causes a lot of temp objects. ShaderKey also uses the optional colorTexSeq shader code for equality test in case of hash-collisions. Previous code simply ignored hash-collisions and used a 1:1 hashCode -> ShaderProgram mapping using our IntObjectHashMap. However, there was no test whether collision occur. +++ Solution would be either 1- Revert fully to the previous code just using an IntObjectHashMap, but throwing a RuntimeException in case of hashCode collisions. In case of a collisions, we would need to produce a better hashCode. This is possible, as the underlying data is fully internal .. etc. 2- Use the IntObjectHashMap as long there is no hashCode collision, then revert back to HashMap<ShaderKey, Shader Program>. +++ This patch implements variant (1), so far no exception has been thrown on multiple demos w/ and w/o diff color-textures.
* Graph Clipping: Use Frustum Clipping using AABBox -> Mv transformed Cube -> ↵Sven Göthel2024-01-202-27/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | Frustum mapping + GraphUI Support AABBox clipping naturally couldn't be transformed into 3D Model-View (Mv) Space, as it is axis aligned and only provided 2 points (min/max). Therefor we map the Group's AABBox to a 8-point Cube, perform the Mv-transformation and then produce the 6-plane Frustum. As before, we cull fully outside shapes within the Group's draw method and perform fragment clipping with same Frustum planes in the shader. With clipping enabled, the 3D z-axis getBounds() depth will be slightly increased for functional Frustum operation. This is also done for setFixedSize(Vec2f). The Frustum planes are copied to the Graph shader via float[4*6] -> uniform vec4 gcu_ClipFrustum[6]; // L, R, B, T, N, F each {n.x, n.y, n.z, d} +++ Concludes related work of below commits - 1040bed4ecc6f4598ea459f1073a9240583fc3c3 - 5cca51e32999a882e2a5f00cb45ecafc824ffd86
* Frustum: Revise code and its Plane definition to support Cube->Frustum as ↵Sven Göthel2024-01-194-51/+199
| | | | | | | | | | | | | | | | | | | | | | | | | well as to extract planes for float[] vec4-shader uniforms. commit 1040bed4ecc6f4598ea459f1073a9240583fc3c3 added AABBox -> Cube -> Frustum mapping (incomplete) and requires Frustum.Plane.set(..) by normal and point-on-plane for distance. Frustum.isOutside(Cube) has been added, testing all its 8-points similar to AABBox. Further all 6 Frustum.Plane shall be extracted to Vec4f and float[], the latter to pass the whole float[4*6] as a vec4[6] uniform array to the shader. +++ Constructor, setter and getter have been adjusted accordingly. Most of the loops have been unrolled. +++ Method names to query Frustum, i.e. 'is*Outside(<Type>)' have been reduced to 'isOutside(<Type>)' where <Type> uniquely indenticates the purpose. Hence only 'isSphereOutside()' is left over.
