this is SE (Simulation Engine) project. The concept is of some equivalent of XNA4, but targeted
for writing simulations. The project aims to be a framework built with F#, while using a native
lib as a renderer, built in Zig with SDL3 (in future, when Zig hits 0.16).

Is still in early stage. (Very early stage!! -> not gonna start vigorous development before October)

Will incorporate a parser for loading .gltf files from FreeCAD or other CAD software.
Then by leverage some simplistic ECS (Entity-Component-System) design and creating Systems
for manipulating geometries and other info in those .gltf files, it will run these systems-based
simulations and rendering the results with SDL3 Zig renderer.

Use the scripts/gltf_formater.fsx to format .glft files into more readable layout.
Look into tests/...fsx files, for examples of the project.
It contains also some simple cylinder .gltf object for helping with development of

• src/gltfLoader.fs
• src/binLoader.fs

:TODO

• develop further the SDL3 zig-lib to have a a more complete and useful API to can actually
  render 'real geometries' with it.
• fix (or total overhaul) the zig2dotnet for better - more robust parsing of Zig files and F#/C# bindings generation.

Instructions

To build src/SE-renderer Zig compiler (0.14 stable) is required.
Make sure that SDL3-devel in available on your machine too. Also it references the dotnet package from SrcCollection-repo, so make sure to clone it, and fix the url to match the relative path on your machine, in src/SE-renderer/build.zig.zon.

    .dependencies = .{
        .dotnet = .{
            .url = "../../../../zig/SrcCollection-utilities/",
            .hash = "dotnet-0.1.0-Xe2rzg9lAQDt8mbQbYrX79liDpq_trtw-ftDLsUzDKW8",
        },
    },

When zig-out/lib/libSE-renderer.so gets compiled, copy that to the directory SE-core/tests/natives
alongside the libSDL3.so (or SDL3.dll if your are on windows).

To build src/SE-core, just

cd src/SE-core
dotnet build
cd tests
dotnet fsi ecs_test.fsx  # to run the example for the ECS part
dotnet fsi renderer_test.fsx  # to run the example for the SDL3 renderer zig lib

And then

P.S. great thanks to SDL3_examples for providing all these valuable examples, and the whole SDL3 GPU API team!!!
