TODO: Optimize day/night mesh updating somehow\r

change texture for material?\r
- Umm... the collecting of the faces is the slow part\r
-> what about just changing the color values of the existing\r
meshbuffers? It should go quite fast.\r
+ - This is not easy; There'd need to be a buffer somewhere\r
+ that would contain the night and day lighting values.\r
\r
TODO: Draw big amounts of torches better (that is, throw them in the\r
same meshbuffer (can the meshcollector class be used?))\r
TODO: Combine MapBlock's face caches to so big pieces that VBO\r
gets used\r
- That is >500 vertices\r
+ - This is not easy; all the MapBlocks close to the player would\r
+ still need to be drawn separately and combining the blocks\r
+ would have to happen in a background thread\r
\r
TODO: Make fetching sector's blocks more efficient when rendering\r
sectors that have very large amounts of blocks (on client)\r
+ - Is this necessary at all?\r
\r
Configuration:\r

- There could be a certain height (to which mountains only reach)\r
