c++ - Is it possible to make a 64 bit positioning system for Unreal Engine/Unity ? -


i've been wondering if 1. 64 bit positioning system make possible transition earth space , further planet, kinda kerbal space program without origin shifting real data derived it. 2. possible , how?

just figure out each integer increment represents , you're done. millimetres should sufficient, that's still +/- ten trillion kilometre range if you're using signed value.

that's going offer more consistency in positioning floating point value, downside each xyz vector 192 bits, or 24 bytes.
