Morton Code for RNS #14

Open RetroGamer74 opened 5 years ago

RetroGamer74 commented 5 years ago

Hi, sorry to ask this here, but I couldn't find other free projects talking about something similar. I guess there is a small diference in the morton calculation for VW RNS 510 devices.

Have you got any info about it?

Thank you very much.

MortonCode contains the position of the city (city center), encoded as Z-values of a Z-curve in the degree of resolution (Level of Detail) 13. The degree of resolution 1 can here include an entire map, the degree of resolution 2 a map section with, for example, half the edge length of the degree of resolution 1, the degree of resolution 3 a map detail with, for example, half the edge length of the degree of resolution 2, etc.

Still not sure how to recreate this though. ;-)
