Minecraft clone prototype with Java and LWJGL (3) смотреть онлайн

5th iteration of my minecraft clone prototype.

Currently investigating continuous world generation, storage and retrieval. This one features a few new tricks. Sectors can now be individually saved to disk and reloaded. The only block data stored is the blocks' id numbers identifying a block definition, which is used to look up other attributes an a library. Sectors that are currently in memory are managed with a multi-level cache structure (not sure if it's necessary to be multi-level). Sectors are generated/loaded as needed, and can be arbitrarily high or low on the y-axis. I also managed to improve memory utilization during sector tessellation.

This prototype currently uses a naive rendering cycle, so there is a lot of overdraw behind the camera. Also sectors are inserted into the cache only as they are requested, so moving the camera can be a bit jerky when crossing sector boundaries (could probably be resolved with pre-fetching them). On an interesting note, when playing with stupidly large camera positions (z = 2^28) I experience the familiar 'far-lands' effect that had since been removed from Minecraft. I managed to fix the rendering issue, but at that distance the camera's z-coordinate lost so much precision that I couldn't move it freely along that axis - no increments less than 1 would work =(.
