I plan to transition PistonWindow to Winit and WGPU. It's part of a long term potential expansion of the current philosophy of the Piston game engine to include content production.

Transition to Winit and WGPU, plus future plans · Issue #317 · PistonDevelopers/piston_window
I believe it is time to make the Piston ecosystem work with Winit and WGPU as the default backends. Piston's modular architecture allowed testing multiple backends, but this was before Winit and WG...

What's the future of Dyon?
The way I do software engineering, is through a lot of experimentation. Experimentation gives me a lot of feedback on issues that impact real world programming.
When you compare Dyon with other languages, it lacks lot of features. There are no traits or classes.

Dyon v0.50 is released! This update makes `dyonrun` return error code properly to the Terminal, so you can e.g. use the Bash command `while true; do dyonrun || break; done`. Dyon now works on Rust stable and was upgraded to Edition 2024.

Turbine-Process3D v0.12 is released! This update adds a general triangle Renderer with support for pre-pre-processing and adaptive sub-tiling for over 2x improved performance. You can customize shader and accumulator.
To wrap this up in a voxel renderer, I use 60 LOC.

Turbine-Process3D v0.11 is released! This update adds Adaptive Sub-Tiling. In some cases it can improve total performance with 10%.
Adaptive Sub-Tiling is when a render tile with many triangles is "split" into smaller tiles, using optimal tile size for splitting.

A great many historians have investigate the relationship to Qumran communities (plural) with early Christianity.
However, if you're looking at the 2nd century it seems by then that Christianity was being shaped/re-shaped by middle-Platonism.

One hobby research project I do is reconstruction of historical context of 2nd century Early Christianity texts.
In recent year, I've been looking for scientific evidence to connect Early Christians with the Qumran community (the Dead Sea scrolls), but there were several gaps.

I've started thinking about adaptive sub-tiles for rendering.
The basic idea is that when a tile of size NxN contains too many triangles >= K, then you split it up by M where M is a divisor of N, such that the average sub-tile has less triangles than K.
Right? It's the worst job that's acceptable.

WE FOUND IT!!! The minimum primbix of value 20:
294698527560839
A primbix is a prime of the form `1 + 2 * r * s` where `r, s` are primes. The primbix value counts the leaves in the associated binary tree. 26 CPU cores worked over a month 24/7.

I figured out that the `PushVariable` design didn't work. When the type `Result<T, String>` is used inside `dyon_fn!`, it produces a `res[any]`, instead of reporting the error to the runtime. So, I kept the old design.

I'm adding support for returning `Result<(), String>` in external functions for Dyon. However, I prefer the `PushVariable` trait as it is. Also, I don't want to introduce too many breaking changes.
So, how do I solve this?
The trick is to use a provided trait method `push_to`:

Rust is so amazingly stable that I often don't notice the version I'm using. However, when I update old libraries, all of a sudden I have to re-learn things because we're doing things differently now.
At the moment, I'm working on updating Dyon to edition 2024.

I've published Turbine-Process3D v0.9.1 with the fix of artifacts when rendering semi-transparent voxels.
I think it's a good default, but I'm open up to reverting this change later if it gets in the way of productivity.
