I spent 6 months building a zero-std, header-only graphics ecosystem from scratch—including my own container library

Hi everyone,

I wanted to share a massive passion project I've been refining: **micro-gl** (and its sister libraries). I needed a lightweight vector graphics engine for constrained environments, but I wanted absolute control over memory and types. I ended up falling down a 6-month rabbit hole.

**The Core Architecture:**

* **Zero Standard Library (**`std::`**):** No hidden allocations. To support this, I spent an intense 3 weeks writing my own standalone container library (**micro-containers**) featuring AVL trees, an array-backed LRU pool, and a linear-probing hash map sized entirely at compile time via templates.
* **Type-Agnostic Math:** The entire rasterizer is templated. It can run on raw `float`, `double`, or custom fixed-point integer types (like `Q` formats) for microcontrollers without an FPU.
* **The Engine Stack:**
* `micro-gl`: CPU-bound rasterizer handling textures, gradients, and Porter-Duff blending.
* `micro-tess`: A precision-agnostic polygon tessellator.
* `nitro-gl`: An OpenGL implementation that compiles C++ shader object hierarchies into monolithic GLSL strings at runtime, cached via MurmurHash.

Everything is purely header-only, allocator-aware, and optimized for extreme cache locality.

Repositories are open-source here:

* Graphics Engine (CPU): [https://github.com/micro-gl/micro-gl](https://github.com/micro-gl/micro-gl)
* Graphics Engine (GPU): [https://github.com/micro-gl/nitro-gl](https://github.com/micro-gl/nitro-gl)
* Custom Containers: [https://github.com/micro-gl/micro-containers](https://github.com/micro-gl/micro-containers)

I would love to hear your thoughts on the template design and compile-time sizing strategies!

Exotic CRTP: Enforcing Strict Interfaces Without Friends Using C++23 Explicit Object Parameters

I’ve been experimenting with CRTP and ended up with a variation that enforces a strict interface/implementation boundary without friend declarations. The goal was to eliminate boilerplate I frequently encountered when trying to encapsulate derived class methods.

The key idea is using C++23 explicit object parameters this + a small access wrapper type so implementations can only be called through the interface layer.

That was about two and a half months ago. Since, I’ve taken the time to better understand it and write an article about it, which you can find below.
As explained there, I refer to this approach as Exotic CRTP.

---

### Example

// Reference example of the pattern
// See: https://medium.com/@felixolivierdumas/exotic-crtp-rethinking-static-polymorphism-with-c-23-89f9e75e8ffd

#include <iostream>
#include <type_traits>
#include <utility>

namespace exotic {

template<typename... From>
struct crtp_access : From... {};

template<typename T>
constexpr decltype(auto) as_crtp(T&& obj) noexcept {
    using crtp_access_t = crtp_access<std::remove_cvref_t<T>>;
    return static_cast<crtp_access_t&&>(obj);
}

}

struct Base {
    void interface(this auto&& self) {
        exotic::as_crtp(self).implementation();
    }
};

struct Derived : Base {
    void implementation(this exotic::crtp_access<Derived> self) {
        std::cout << "Derived implementation" << std::endl;
    }
};

int main() {
    Derived d;

    d.interface(); // perfectly works

    // d.implementation(); -> doesn't work, Derived only allows .interface()
}

---

Not sure yet if this is actually useful in real conditions or just a different way of structuring CRTP, but it seems to be genuinely powerful.

Full write-up here: https://medium.com/@felixolivierdumas/exotic-crtp-rethinking-static-polymorphism-with-c-23-89f9e75e8ffd

Curious how this compares to traditional CRTP + friend patterns in real codebases :)

C++ Show and Tell - June 2026

Use this thread to share anything you've written in C++. This includes:

* a tool you've written
* a game you've been working on
* your first non-trivial C++ program

The rules of this thread are very straight forward:

* The project must involve C++ in some way.
* It must be something you (alone or with others) have done.
* Please share a link, if applicable.
* Please post images, if applicable.

If you're working on a C++ library, you can also share new releases or major updates in a dedicated post as before. The line we're drawing is between "written in C++" and "useful for C++ programmers specifically". If you're writing a C++ library or tool for C++ developers, that's something C++ programmers can use and is on-topic for a main submission. It's different if you're just using C++ to implement a generic program that isn't specifically about C++: you're free to share it here, but it wouldn't quite fit as a standalone post.

Last month's thread: https://www.reddit.com/r/cpp/comments/1t6eg13/c_show_and_tell_may_2026/

Logicwise – A Factory for C++ Concepts

Logicwise is intended to validate a bunch of types or values around a simple atomic concept using straightforward syntax.


Say, you have several types, and you want to ensure any of the following:

\- Each type satisfies some constraints.

\- All types must be distinct.

\- No type may inherit from any other type.

\- Each type must match any type from another type list.

You will find an intuitive solution in Logicwise: https://github.com/frog-singing/Logicwise

It even allows you to forge your requirement into a new concept.


Happy to share my design thoughts with you!
