Unreal Engine 3 brings you Gemini, the multi-threaded rendering system. Gemini creates a lush visual reality and provides the power necessary for photorealistic simulations. Deliver stunning results with this flexible and highly optimized renderer.

The Unreal Rendering System

Unreal Engine 3 features a 64-bit color HDR rendering pipeline. The gamma-correct, linear color space renderer provides for immaculate color precision while supporting a wide range of post-processing effects such as motion blur, depth of field, bloom, ambient occlusion and artist-defined materials.

Unreal Engine 3 supports all modern per-pixel lighting and rendering techniques, including normal mapped, parameterized Phong lighting; custom artist-controlled per material lighting models including anisotropic effects; virtual displacement mapping; light attenuation functions; pre-computed shadow masks and directional light maps.

Unreal Engine 3 provides volumetric environmental effects that integrate seamlessly into any environment. Camera, volume and opaque object interactions are all handled per-pixel. Worlds created with Unreal Engine 3 can easily feature multi-layered, global fog height and fog volumes of multiple densities.

Unreal Engine 3 also supports a high-performance texture streaming system.

Additionally, Unreal Engine 3’s scalability settings ensure your game will play on a wide range of PC configurations.

Unreal Engine 3 supports Direct3D 9 and Direct3D 11. Direct3D 11 allows the utilization of new hardware features like tessellation. This implementation supports flat and smooth tessellation (PN-triangles). The tessellation level is adjustable and view dependent. The tessellated mesh can be further manipulated in the material editor for static or animated displacement effects.
