Graph Type Rendering Updates (Graph UI)

Screenshot w/ debug code demonstrating the Frustum clipping w/ rotation.
The red-part is clipped by the shader, while the other thousand Glyphs
of that glyph-grid are culled by the Group.

After having reached UI usability with widgets and clipping, the following items are becoming more interesting

- Fix general issues with current implementation and API, if any
- Fix Graph rendering bugs (Tessellation)
- Implement a one-pass smooth AA Graph renderer, allowing to save resources of pass-2 FBO supersampling
- Allow passing per-vertex color to Graph Outline (API)
- Add subtitles in MediaPlayer GraphUI widget
- Add video encoding in our FFMPeg binding, i.e. an FFMPEGMediaRecorder (Encoding + Multiplexing)

Updated FontView01 video in above blog with performance issues fixes, see Bug 1488, Bug 1489 and Bug 1490.

Good job, it's a lot better than what I would be able to do by myself. If you go on, I'll consider dropping Ardor3D UI because JOGL itself will cover my needs.

Continuing with the GraphUI UI work (Bug 805)
Bug 1491 Comment 5:
See a demos w/ > 200 GLMediaPlayer instance running in a GraphUI Ranged Group,
having 36 instances being visible and displaying new decoded images.

Full-Feature & High-Performance GraphUI GLMediaPlayer Video Player
Demonstrating new audio and subtitle selection and rendering as well as a performance demo w/ 348 GLMediaPlayer instance running in a GraphUI RangedGroup, having 16 and 36 instances being visible and displaying new decoded images. A little teaser in our Graph Type Rendering and UI saga.

GraphUI MediaPlayer – Feature Complete
Posted on 2024-02-07 by Sven

After showing our GLMediaPlayer & GraphUI MediaPlayer progress, I can now conclude this demonstration being feature complete with text/ASS & bitmap subtitles including international fallback-font (Asia etc), mouse-over time-code & still-images on the progress-slider, proper aspect-ratio cropping, chapter visibility & hopping as well as displaying full stream information. Another milestone in our Graph Type Rendering and UI saga. ....

Fixing JogAmp’s Graph Delaunay Tessellation of Complex Non-Convex Shapes
https://jausoft.com/blog/2024/02/13/fixing-jogamps-graph-delaunay-tessellation-of-complex-non-convex-shapes/

...

The solution was to apply intersection tests for non-convex shapes to reject new CCW  and non-circumcircle triangulation candidates in our Delaunay tessellator.

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 (hole) or outer boundaries of the given polygon.....

.. next up would be proper AA with 1-pass shader dropping the 2-pass FBO/VBAA.
Until then .. well, our 2-pass or the GPU's fsaa (msaa) should be used.
