4A-Engine
4A-Engine is a complete game development framework for next-generation consoles and DirectX9-equipped PC’s, providing the vast array of core technologies, content creation tools, and support infra¬structure.

Rendering
The gamma-correct, linear color space renderer
High-Dynamic Range Rendering Using Floating-Point buffers, allowing for Tone Mapping, Expo¬sure Adaption, and Blue Shift, for camera/eye perceptual rendering.
Deferred Shading – allows hundreds of lights in frame, in huge, complex scenes
Only Dynamic Lighting – and ability to use light-shaders, with dozens of special effects
Weather and Day/Night model
Global Illumination Effects
Virtual Displacement Mapping
Hierarchical Per-pixel Occlusion Culling.
Realtime color correction
Film grain and Noise
Depth Of Field
Motion Blur
Analytical AA

AI & gameplay
Virtual vision, hearing, smelling – realistic, believable and time and memory efficient implementa¬tion enables characte rs to sense objects in a natural way, depending on the object velocity, luminocity, etc. - which is very useful for making stealth missions
Goal selection using motivational graphs enables to setup character to select goals using his, sometimes orthogonal, motivations – make him survive and at the same time complete a story task given, for example.Action selection using Goal-Oriented Action Planning enables character to build dynamically an action sequence which reaches the goal selected. This makes it possible (using a handful of simple actions) to produce very intelligent behaviors. This technique produces intelligent behaviors even in situations which were not taken into account by the developer

Productivity Environment & toolset
Level Editing – fully integrated into the engine – you are always one click away from playing the game

Export tools for 3D Studio Max, Maya for bringing weighted meshes, skeletons, and animation sequences into the engine.
Extensible particle system with visual editor, supporting particle physics and environmental effects.
Physics modelling tool

Sound
Support for all major output formats of each platform, including 5.1 surround sound and certifica¬tion-quality Dolby Digital.
3D sound positioning, spatialization, Doppler shift.
Environmental effects, including EAX-4.0

Streaming Technology
