PC_Transform(pcpoint, integer, json) : pcpoint #15
Description
PC_Transform(
pt pcpoint, -- transformed point
pcid integer, -- target schema
mapping jsonb -- input/output column mappings, including transformation calls
) : pcpoint
This proposal follows roughly the python mockup of @dustymugs (https://github.com/dustymugs/pgpointcloud_utils/tree/master/pgsql) but limits itself to a fixed set of c-coded transformations rather than evaluated expression strings.
