ccording the 402's interview with Dutch Mag Power Unlimited MW2 is going to be using "Texture Streaming", if we are talking here about the generic texture streaming principle here are a few explanations:
The Basics
The concept is simple: load the top mip level of textures as the camera gets close to them. If everything is working properly, they’ll be loaded before they are actually needed. If not, there can be a slight pop as the top mip level appears.
The Goal
The goal, of course, is to be able to have more memory for textures resulting in the possibility of levels size a lot larger than usual.
Which Textures Are Usually Streamed
All shader textures are streamed. This includes:
* color maps
* normal maps
* gloss, parallax, incandescence maps
* detail maps
All other kinds of textures are not streamed:
* light maps
* blend maps
* effects textures
Note that this isn't a new technology, its been used since early 2007 and possibly before in games such as UT3, Quake Wars and many more. |
