94160506 MDU6SXNzdWU5NDE2MDUwNg== 462 Create a way to calculate computed coordinates 2599958 closed 0     2 2015-07-09T21:54:50Z 2019-03-03T12:23:58Z 2019-03-03T12:23:58Z NONE      

Create computed coordinates in a lazy way, given a user defined equation for defining these coordinates.

E.g.,

my_depths(params): # do the calculation return depths

Then, link ds.salt.z to my_depths, such that

ds.salt.z

returns the depths, calculated on request. Or better, an object that returns values only upon indexing.

See, e.g., The equations: https://github.com/hetland/octant/blob/master/octant/depths.py

One way to do the lazy calculations just in python https://github.com/hetland/octant/blob/68f51005480c8cb9f83098b0f751b4e8086c11b5/octant/roms.py#L244
