| 51 | Provides a simple mechanism of 'memory mapped IO', but compatible for Ogre 1.4 |
---|
| 52 | |
---|
| 53 | Files are stored as shared_array<char> in a static map with the archive names |
---|
| 54 | (imaging the different archives as resource locations). This map then contains |
---|
| 55 | yet another map with the actual files. |
---|
| 56 | If you want to know why we make such a fuss, contact GraphicsManager::upgradeToGraphics() |
---|
| 57 | for more information. |
