Introduction

The Dagor Engine is an open-source game engine by Gaijin, continuously updated since 2002 for high-performance gaming and realistic graphics.

Platform Support

Supports Windows PC, Linux, iOS, Android, Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X/S.

Games Created with the Dagor Engine

Powers games with detailed physics and large-scale environments, including:

• War Thunder: Vehicular combat game with air, land, and sea battles across historical eras.

• Enlisted: Squad-based WWII first-person shooter with large-scale battles.

• War Thunder Mobile: Mobile adaptation of War Thunder for iOS and Android.

Key Features

• Graphics Engine: Supports DirectX 12, Vulkan, and Metal APIs.

• Physics Engine: Dagor supports third party open source industry standard solutions for physics simulation: Jolt Physics (preferable) and Bullet Physics.

• DaGI (Dagor Global Illumination)

  • Optimized for efficient global illumination on huge dynamic scenes with low memory usage (less than 1ms on PS4!), and with raytracing support for modern hardware.

  • Simulates indirect lighting and light bouncing for realistic scenes:

    • GDC talk: Scalable Real-Time Ray Traced Global Illumination for Large Scenes

    • Dagor Engine 5.0: light and shadows: Global Illumination, contact shadows, shadows on effects

• Darg (Dagor Reactive GUI)

  • Reactive UI framework based on Quirrel scripting.

  • Supports stateful components and modular development with native code integration.

• Dagor ECS

  • Data-driven Entity Component System for modular game development.

  • Manages entities through templates, supporting parallel processing and cache efficiency.

• Render Framegraph

  • Directed acyclic graph for defining frame rendering sequences.

  • Allows flexible integration of game-specific and engine features.

• daNetGame Framework

  • Modular platform for comprehensive game development.

  • Integrates core systems like rendering, physics, networking, and audio.

• Daslang

  • Scripting language for interacting with core systems like rendering and physics.

  • Enables dynamic content management and engine functionality extension.

• DSHL (Dagor Shader Language)

  • Specialized language for shader creation and management.

  • Supports advanced features like conditionals, custom data types, and hardware-specific optimizations.

• Toolset

  • Dagor Editor: Level editor with terrain editing, prefab placement, and plugin support.

  • Asset Viewer: Resource editor and viewer for special effects, particle systems, and animations.

  • Impostor Baker: Tool for optimizing rendering with simplified 3D object representations.

  • Importers and Exporters: Integration with 3ds Max, Maya, and Blender.

• Networking Subsystem

  • Scalable, low-latency architecture for multiplayer games.

  • Supports TCP and UDP protocols, with built-in tools for debugging, lag compensation, and data compression.

• Audio Engine

  • Uses FMOD library for 3D sound, DSP effects, and multi-channel support.

• Animation System

  • Supports skeletal and procedural animation, blending, morphing, and various controllers, including Inverse Kinematics, additive animations and motion matching.
