metro2033的4AEngine

很高兴看到这个他们自己研发的引擎，名字叫4AEngine：

最近看到的宣传点是在dx11和nv的physx上。

 

3D方面的feature：

 

• The gamma-correct, linear colour space renderer
• High dynamic range rendering (HDR) Using floating-point buffers, allowing for tone mapping, exposure adaption, and blue shift, for camera/eye perceptual rendering
• Advanced deferred shading - allows hundreds of lights in frame, in huge, complex scenes
• All lighting is fully dynamic (including sun and skies), ability to use light-shaders, with dozens of special effects
• Umbra and penumbra - Correct soft shadows, including shadows correctly curved on bumped surface. Shadows from semi-transparent objects like particles.
• Weather and day/night model, including light scattering model and god-rays
• Volumetric fogging and lighting, even in animated, non-constant density media
• Global illumination effects and real-time reflective lights
• Parallax occlusion maps and real (geometric) displacement mapping
• Hierarchical per-pixel occlusion culling
• Real-time colour correction, film grain and noise, correct depth of field
• Velocity preserving motion-blur on a scene with millions of polygons and complex shading detail (including object blur)
• Deferred reflections - allows a lot of planar real time reflections in a single frame, like water, glass, etc.
• Ambient occlusion calculated on both the global scale (pre-calculated) and in real-time in screen space (SSAO)
• In addition to standard MSAA, the engine features analytical anti-aliasing (AAA) and "deferred super-sampling" modes which have much lower impact on frame-rate, while correctly ant-ialiasing all surfaces and not just edges
• Renderer is highly multi-threaded for multiple CPU cores.
• Plus: per-pixel lighting, bumpy reflections and refractions, animated and detail textures, shiny surfaces, cosmetic damage using albedo and bump blending, soft particles, etc.

deferred shading, AO基本是业界标准了，大家都用。

GI这么关键的东西就简单带过啊。。。shit！

多线程renderer很好，利用了dx11的feature，console上也可以做到。

AAA不知道什么东西，在问中！

 

还有其他一些pc方面的东西，不过基本上是基于dx11显卡（dx11显卡都太强力了，性能在console显卡n倍甚至近10倍）的能力得到的提升，大texture，更高精的filter，没看到技术上的进步。

里面说3平台用同一套代码，应该是没有做到极度优化的结果。

 

不过支持3D模式，这个不错哦。

 

不管怎么样，虽然一出场不是那么强力和惊艳，也是很不错啦，希望这帮哥们能够长久积累和提升这个engine，成为市面上顶级engine之一。
