org.terasology.world.chunks.internal.ChunkImpl
Chunks are the basic components of the world. Each chunk contains a fixed amount of blocks determined by its dimensions. They are used to manage the world efficiently and to reduce the batch count within the render loop.
Chunks are tessellated on creation and saved to vertex arrays. From those VBOs are generated which are then used for the actual rendering process. @author Benjamin Glatzel @author Manuel Brotz
