## What it is
Flex Engine is a personal cross-platform game engine written in C++ with a Vulkan rendering backend, built as a playground for learning real-time rendering and simulation techniques. It includes a scene editor, in-game scripting language with a virtual machine, and advanced rendering features like PBR, SSAO, cascaded shadow mapping, and GPU particle simulation.

## Use cases
- study how a Vulkan renderer is implemented
- learn real-time rendering techniques like PBR and SSAO
- explore game engine architecture in C++
- see GPU-based particle simulation with compute shaders
- build a personal game engine project for learning
- implement cascaded shadow mapping or temporal anti-aliasing

## When to choose
- you want readable source code to learn Vulkan and real-time rendering
- you need a reference implementation of PBR, SSAO, or shadow mapping techniques
- you are studying how game engine editors, scripting VMs, and profilers fit together

## When to avoid
- you need a production-ready engine for shipping games
- you want community support, documentation, or frequent updates
- you need cross-platform support beyond Windows and Linux

## Facets
