<paradust> Why is blockdata serialized as three separate arrays (array of all param0, followed by param1, followed by param2) instead of just copied node by node? |

MTDiscord |
<paradust> oh probably a compression thing? nevermind |
| 11:06 |

<luatic> Also useful on the Lua side of things (VoxelManip): Having three large arrays has much less overhead than having one large array where every entry is a table of 3 values. |

also generally one is interested in a single param across multiple neighboring nodes, so you want to store them in separate arrays as a cpu cache optimization |

<paradust> but their in-memory representation is a single array, it appears |

but for serialization it'll be to optimize the compress yeah |
