Atmospheric Engine

Atmospheric Engine is a cross-platform 3D game engine developed in C++. The project is a labor of love, acting as my stepping stone to gain a deeper understanding of graphics programming concepts and practices.

Heightmap Terrain w/ Dynamic Tessellation

Features

• PBR texturing, point/directional shadows, post-processing effects
• Heightmap terrain with collision and shader-based dynamic tessellation
• Custom key binding system
• Immediate-mode debug UIs for engine subsystems
• Simple job system implementation

Platforms

• Apple Silicon
• Apple Intel (unsure?)
• Windows (broken)
• Linux (planned)

⚠️ WARNING This project is a work in progress and may be unstable at this stage.

Building

Follow the steps below to build the engine:

1. Install prerequsites:

• CMake (required)
• EMSDK (optional)

2. Clone this repository

git clone --recurse-submodules https://github.com/painfulexistence/AtmosphericEngine.git

3. Setup Vcpkg

cd AtmosphericEngine
./vcpkg/bootstrap-vcpkg.sh -disableMetrics

4. Build the project with CMake

cmake -S . -B build
cmake --build build

Usage

The engine includes four example projects to help you get started. Please note that the API is still evolving and may change in the future. To get started, you can check out the HelloWorld example.

Examples:

• Hello World
• Terrain (dynamic-tessellated)
• Maze FPS
• Breakout 2D (WIP)
