LemonFX

A batteries-included Vulkan renderer library for C++. LemonFX provides a simple, Raylib-inspired API while leveraging modern C++17 and Vulkan features for high performance.

Features

• Single-header library - Just include lemonfx.hpp and you're ready to go
• RAII wrappers - Automatic resource management with move semantics
• Simple API - Clean, intuitive interface inspired by Raylib
• Modern C++17 - Uses std::optional, move semantics, and modern patterns
• Validation layers - Built-in debug support for development
• Window management - Integrated GLFW for cross-platform windowing
• Swapchain handling - Automatic resize and recreation

Requirements

• C++17 compatible compiler
• Vulkan SDK (1.2+)
• GLFW3
• CMake 3.15+

Quick Start

#include <lemonfx.hpp>

int main() {
	// Initialize context
	lfx::Context ctx;

	// Create window
	lfx::WindowConfig config;
	config.title = "My App";
	config.width = 1280;
	config.height = 720;
	lfx::Window window(ctx, config);

	// Main loop
	while (!window.shouldClose()) {
		window.pollEvents();

		if (window.beginFrame()) {
			window.clearColor(lfx::Color::Blue());
			window.endFrame();
		}
	}

	return 0;
}

Building

mkdir build && cd build
cmake ..
cmake --build .

Examples

See the examples/ directory for sample programs:

• hello_window.cpp - Basic window with color clearing

Architecture

LemonFX is structured around a few key classes:

• Context - Manages Vulkan instance, device, and queues
• Window - Handles window creation, swapchain, and frame rendering
• Shader - SPIR-V shader module wrapper
• Color - Simple color representation with preset colors
