This list exposes building blocks for potential use and business case scenarios using Java & JogAmp on Desktop and Embedded Devices.
Notably Graph & Graph UI as well as Wayland & Vulkan support could be of interest here?

Graph
Graph/GraphUI Progress Blog Entries
Desired Work Items
This is an ad-hoc list of desired features and fixes, which shall result in proper bug-reports soon.
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)
- Use of super-sized triangles to render Graph lines & curves to allow
- Using a one-pass smooth AA Graph renderer to save resources otherwise used in our pass-2 FBO supersampling renderer
- Generate outlines, i.e. outlined fonts
- Generate special effects like glowing/pumping outlines indicating selection etc
- Allow passing or better attaching per-vertex color to Graph Outline (API)
Add subtitles in MediaPlayer GraphUI widget(done)- Add video encoding in our FFmpeg binding, i.e. an FFMPEGMediaRecorder (Encoding + Multiplexing)
Further more, if so desired, a C++ implementation of our Graph + GraphUI framework may also be of interest.
In case any company or organization is interested and likes to support this work and may also like to receive support in adopting this framework, please contact Göthel Software e.K.
OpenJDK Compatibility / Integration
Objectives should be to allow seamless integration into OpenJDK's deployment and JVM launch methods.
A dual JAR file to be used with and without modules is desired, however it seems that certain JAR options are not available with this configuration if our classes are not build as modules itself.
An optional JVM Launch Pad (JLP) might be helpful, even though it instructs further complexity and is not helping with a vanilla OpenJDK deployment.
OpenJDK >= 11
See Bug 1404
JVM Commandline Parameter
Current used 'add-opens' in my JogAmp test scripts for Java >= 11, covering all AWT utilization including background erase is:
--add-opens java.desktop/sun.awt=ALL-UNNAMED --add-opens java.desktop/sun.awt.windows=ALL-UNNAMED --add-opens java.desktop/sun.java2d=ALL-UNNAMED
OpenJDK >= 2x
See Bug 1505
JVM Commandline Parameter
Current used 'add-opens' in my JogAmp test scripts for Java >= 23, covering all AWT utilization including background erase is:
--add-opens java.desktop/sun.awt=ALL-UNNAMED --add-opens java.desktop/sun.awt.windows=ALL-UNNAMED --add-opens java.desktop/sun.java2d=ALL-UNNAMED --TO_BE_DETERMINED
Graph UI
Graph UI will enable an immersive UI within the 3D scene on the desktop, mobile and on bare-metal embedded systems without a windowing system.
Graph UI utilizes Resolution Independent NURBS Curves Rendering using Programmable Graphics Pipeline, i.e. rendering curves directly on the GPU, resolution independent [ paper, slides ].
This method allows us to have an ultimate fast font and UI rendering engine, suitable for all devices and applications. No CPU based curve nor font pre-rendering (matching a target resolution) is required.
Think of an integrated QT or OpenJFX in your 2D/3D application working on desktop and embedded devices even w/o any windowing system on top of a plain console DRM/GBM as support by JOGL(EGL) and NEWT as demonstrated by Xerxes on a Raspberry Pi4.
Reimagine Java on Desktop & Bare-Metal Devices demonstrates the updated Graph Curve Rendering and UI, while this update shows clipping and widgets. Further updates will be posted here....
Notably the Graph Curve Rendering is almost feature complete, as well as our own user input including gesture detection within NEWT.

NEWT + Wayland
Currently NEWT supports the X11/Xorg windowing server on Unix alike platforms.
It might be desired to add direct support to Wayland, as we already added support for bare metal devices w/o a windowing system via the Linux DRM/GBM console mode throughout JOGL + NEWT.

Video Encoding/Decoding & Player
Across our releases, we supported video encoding and decoding (with a player) based on either FFmpeg or Android's library as shown in this clip at 2:12 min mark.
Goal would be to
- Update general ffmpeg video decoding support
- Enhance ffmpeg video encoding support
- Potentially add better control about video-frame to framebuffer control for editing software

iOS Enhancements
Early iOS support has been demonstrated in 2019
Enhancing this port would allow to use JogAmp in a similar fashion as on Android, but using an OpenJDK iOS build.
