Getting Started

What Is Unigine

Unigine engine is a complete 3D platform for creation of fully interactive virtual worlds. This powerful and extremely flexible solution is used for game development, real-time simulation (military, transportation, training, etc.) and visualization (architecture, media installations).

Moreover, it is a cross-platform solution available on a broad range of platforms:

  • From low-end to high-end PCs (Windows, Linux, Mac OS X)
  • Mobile devices (iOS, Android)
  • Consoles (PlayStation 3)

For more details, see hardware requirements.

What Is Inside

Unigine is an all-in-one solution with the following subsystems ready to be used out of the box:

Renderer Photorealistic graphics and effects of stunning visual quality:
  • Tessellation, real-time global illumination, DOF with bokeh effect and much more
  • Multiple APIs: DirectX 9, DirectX 11, DirectX 11 of DirectX 9 feature level, OpenGL, OpenGL ES, PS3
  • Cinematic post-processes
  • Flexible material system with inheritance support for convenent editing and ultra-fast rendering
  • Support of GLSL and HLSL languages for custom shaders, if necessary
  • Stereo 3D rendering (including NVIDIA 3D Vision, NVIDIA 3D Surround and iZ3D stereo support)
  • Multi-monitor configurations (monitor walls, CAVEs)
  • Panoramas and single or mitti-node projections

Effective management of resources in the scene and control of background streaming
  • Completely automatic indoor and outdoor scene management based on BSP trees
  • Dynamic asynchronous data streaming in the background done automatically by the engine
  • Zone-based loading of resources on demand
  • Dynamic worlds merging
  • Double precision coordinates libraries for extremely vast worlds

Additional easy-to-use rendering optimizations to achieve the best of performance:
  • Flexible LOD system
  • Automatic instancing for meshes and animations
  • Batch rendering of huge number of objects
  • Occluders for complex environment culling
  • Portals and sectors for additional optimization of indoor environments
  • Performance profiler

All you need to do is just add them. These objects are available strait out of the box.
  • Sky with clouds
  • Sun with atmosphere and other types of lights
  • Height map-based terrain
  • Water (ocean, rivers or lakes)
  • Grass
  • Particles
  • Volumetric objects for beams, fog and clouds
And much, much more

Scripting System Powerfull scripting system: write one code for all platforms!
  • Object-oriented programming
  • UnigineScript language with a syntax similar to C++ (*.h and *.cpp files are used for Unigine scripts)
  • Zero compilation time - just reload the world to see changes in effect
  • More than 4000 of functions and classes avaiable
  • Very fast built-in 3D math (vectors, matrices and quaternions)
  • Transparent interconnection with C++ side, if necessary
  • Multi-threading support
  • Regular expressions support
  • Full state saving and restoring
  • Built-in debugger

GUI Comprehensive set of widgets, containers and dialogs, including 3D GUI positioned right in the scene
  • UI files in XML format for easy creation of widgets and their layout
  • Flash-based GUI: add fully interactive menus or HUDs and with just one code line
  • Localization packs support
  • IME support for Eastern languages
  • Unicode (UTF8) and TTF support
  • Easy skin changing
  • Video playback (OGG Theora) widget
  • Multi-monitor GUI plugin for convenient edtiting of worlds

Pathfinding Pathfinding module help you create AI for your project in no time
  • 2D and 3D pathfinding
  • Dynamic obstacle management via masks
  • Pathfinding area prorities
  • Deferred pathfinding calculations for optimal performance

Network Basic real-time networking functionality both in core framework and an additional network plugin
  • RakNet low-level integration plugin (secure connections, NAT punch-through)
  • LAN server discovery
  • Object state replication
  • Trasparent interconnection between network events and UnigineScript
  • UDP and TCP protocols support
  • Telnet protocol support for remote control over Unigine applications (for example, on mobile devices)
Sound Robust sound module with true-to-life audio effects for full immersion experience in your 3D world
  • Unlimited number of 3D sound sources
  • Streaming of sounds
  • Directional and non-directional sounds
  • Doppler effect and distance attenuation
  • Sound occlusion for interaction with environmet
  • Multiple reverberation zones
  • Playback of WAV and OGG files
  • Dolby Digital 5.1 surround sound supported out of the box
Interactivity Create different dynamic interactions in your world with the following systems:
  • Keyframe-based Tracker for adding day-night cycles, creating cinematics and animating interactive objects
  • Gragh-based Skinner for fast animations of characters created using visual blocks
  • Schemer for visual scripting (custom blocks can be added)
  • Triggers fired off when nodes or physical bodies enter/leave a certain area
  • WorldTransform to move an object along the spline
  • WorldTransformBone to attach objects to charater's bones
  • WorldExpression to execute any UnigineScript code snippet within a certain radius
World Editor With WYSIWYG world editor right in your Unigine application you get instant preview with final quality. Tweak settings and make your world shine!
  • Add and manage objects, lights and effects
  • Create and set up materials for objects (material hierarchy is supported)
  • Set up rendering settings
  • Set up and play physics
  • Bake prefabs into NodeReferences. After the prefab is added, you can change one and the other will automatically follow
