[postgis-devel] 2.5D TIN Operations

[Darafei "Komяpa" Praliaskouski]

Hi,

Let's imagine I have a bunch 2.5D TINs representing some measurement - say,
a travel time to a central point. I want to perform operations on top of
these:

 - for each TIN in the group I would like to get a 2D polygon of bounds
where it is the lowest in the group - "here is delivery area for this
office" if you wish;

 - combine two TINs into a new one defining a lowest part of surface -
"here is our delivery time map".

I understand the maths of this, but how an API for that can look like? Any
examples to look at?
