Trim 420 Status
The latest version is considered to be the Delphi FMX project with 2D graphics. Please find the source code of this project on GitHub.
A recent version of the Trim 420 application is available from the Windows Store:
You could as well load the free Trimm420 iPad App (without space between Trim and 420), but note that this one is not the latest version.
Keeping the cross platform versions up to date is currently difficult because of missing subscription to the latest version of the tool used, Delphi. Perhaps a new attempt with cross-platform development will be made later.
It is of course a possibility that native apps for specific platforms will appear sooner or later. Already, the source code of a slim C# application with excellent 3D graphics is available at GitHub.
Use RG34 and latest Visual Studio to run the app in the debugger.
RG34 uses the HelixToolkit package which uses DirectX and is for Windows only. New applications targeting other platforms should perhaps have a look at this app, as an example, and then implement a similar set of features.
The source code of the existing Free Pascal (Lazarus) version is also on GitHub. It did compile directly on a Mac, but the project is on hold.
A native Android version with 2D graphics has been started, but is currently also on hold. Some help with a native Android version would be welcome.
New in 2023 is the progress that happened to the federgraph project.
