[X3D-Ecosystem] glTF editors…

[John Carlson]

I’m guessing stride is more about how to group constant numbers of sfs in
an mf?  Kind of like stride while walking.   Arrays often have length or
size.   So I think you could look up something in X3DArrayField.

http://vis.arc.vt.edu/projects/osnap/doc/x3d/fields/X3DArrayField.html

In the above, you can use getValue() to return an array list, which you can
get the length of the array list from.

SAI is your friend.

Nicholas, I’m wondering why the abstract class methods aren’t mentioned in
the implementations in the fields package for example, MFInt32.

I don’t know glTF, and perhaps Joe is speaking of that?

Since array list is probably a list of arrays, maybe stride is the length
of each array?
