This is an experiment to evaluate tech stacks for a modern "NEngine", specifically as a c++ project. NEngine is an interactive simulation engine specialized in hyperspace generalization (for now, then comes non-euclidianess and, the special sauces ^_^).

Initial NEngine Project

The conclusion was that c++ although a great language, and the current industry standard for interactive simulations, it is definetily on the dust now in a wide range of features, and its cleary being replaced by rust and zig in the appropiate parts, and rust specially is gaining an unprecedent adoption in some hard industry grounds.

Given this and the project specific constraints (huge codebase, many combinatorial features , and a specially repetitive need for generalized metaprogramming on N, etc) made it difficult to choose one over the other, but rust had to be choosen, as it is the most adopted, stable, and adecuate to handle the unprecedent, and inherent complexity. Zig would be ideal, comptime absence is a big pain on rust, but the tradeoffs wherent enough, specially for the potential size of the system.

Anyways, the language is not the most important, but the abstract types we can derive to create a real generalized solution to interactive simulations on exotic geometries. When (if) the promised language of the future comes, this will be happily rewriten on it, and its part of this codebase ethos. For now, rust is almost perfect to this, and zig can be included where it shows (if appropiately needed), and who knows, its should not be that difficult to add comptime to rust (sigh).

This repo will be updated anytime I find utility on implementing an algorithm in c++ to benchmark them against rust and zig versions. It already counts with a very raw vulkan renderer and basic abstractions for n-d geometric algorithms, like tensors.

Im rewritting an old n-d web interactive simulation engine into modern soil (?) c++, just for the sake of it (?).

The "primary task": nd engine: graphics/physics graphics: correct n-d rendering (volumetric rendering && superposition), vol-RTX physics: base solids, constraints

EXTRA: after the bare minimum of the primary task, im switching to rust.

NOTES: c++ modules lack support
