@ -9,4 +9,4 @@ The principle is following: in normal forward shading (non-deferred) the shading
This is especially effective when we're using very expensive/complex pixel/fragment shaders AND we have many overlapping objects. **Sometimes deferred shading may be replaced by simply ordering the rendered models**, i.e. rendering front-to-back, which may achieve practically the same speed up. In simple cases deferred shading may not even be worth it -- in [LRS](lrs.md) programs we may use it only rarely.
Deferred shading also comes with complications, for example **rasterization [anti aliasing](anti_aliasing.md) can't be used** because, of course, anti-aliasing in G-buffer doesn't really make sense. This is usually solved by some [screen-space](screen_space.md) antialiasing technique such as [FXAA](fxaa.md), but of course that may be a bit inferior. **Transparency also poses an issue**.
