## What it is
Diligent Engine is a modern cross-platform low-level 3D graphics library and rendering framework that abstracts Direct3D11/12, Vulkan, Metal, OpenGL/GLES, and WebGPU behind a consistent front-end API. It uses HLSL as a universal shading language and is designed as a graphics subsystem for game engines, simulations, and 3D visualization applications.

## Use cases
- build a cross-platform 3D renderer without writing per-API backends
- write HLSL shaders that run on Vulkan, Metal, and Direct3D12
- develop a game engine graphics subsystem
- create interactive 3D visualization applications
- add ray tracing or PBR rendering to a C++ project
- target WebGPU and legacy OpenGL from the same codebase

## When to choose
- you need one C++ codebase rendering across D3D11/12, Vulkan, Metal, OpenGL, and WebGPU
- you want low-level control over modern graphics APIs with a clean abstraction layer
- you need HLSL as a universal shading language across backends
- you want a permissive Apache 2.0 license for commercial use

## When to avoid
- you want a full game engine with editor, physics, and asset pipeline out of the box
- you prefer a high-level scene-graph API rather than a low-level rendering layer
- your project is not in C++ or lacks CMake build integration
- you only target a single platform and can use the native API directly
