I'm assuming that you don't have connections from slice to slice.
Having 35 in one and 26 in another does not fit a regular grid. So I
would say you are looking at a Group of fields. So what are you going
to use for line decimation?

Hello, all,
this is a type of the "ragged array" problem I have mentioned before:
I have a dataset that is derived from a 3D videometric
scanner that produces sets of
linear arrays of points, each array representing a scanline.
simplified is looks like:
scan 0 35 points
x0 y0 z0
.
.
.
x34 y34 z34
scan 1 26 points
x0 y0 z0
.
.
.
x25 y25 z25
scan 2 49 points
x0 y0 z0
.
.
.
x48 y48 z48
What sort of DXobject am I looking at?
I would think this could be a series ( do series members have to be
of the same length?) or a multigrid,
but it looks like each of these structs has an artificial
limit of 21 members! Here I have something like 1000 scans
of 400 points each.
There are some operations, like line decimation,
that I would like to perform line-by-line,
then later merge these decimated lines into an
unorganized point loud and triangulate it.
This would seem also to be like a rake of streamlines.
What's the best way to handle such a structure in DX? In C parlance it
would be represented by an array of pointers, each pointer
pointing to a sub-array of different length:
0-> {1,4,6,7,8,}
1-> {9,2}
2-> {5,5,5,5,6,7,8,3,12}
3-> {7}
etc..
