John,
I believe the quoted passage means:
A circle (or any other shape) would be represented by rectangularly oriented
points.
(I guess this means they don't have to be square, though I would expect
square orientation suits a circle, non-square perhaps for an ellipse.)
Possible representations (in non-proportional font) in two dimensions:
.....
.......
.......
.....

depending on the desired resolution in each direction.
I didn't understand what you said about a circular base requiring fewer
points.
I am sure others can give a more detailed explanation/correction.

Subject: gridded3dset
Hello,
Please excuse my ignorance in VisAD. Suppose I want to generate a shape
with say a circular base, is it still possible to use gridded3DSet with a
manifold dimension of 2? Since a circular base has less points in a
rectangular grid system than a rectangular base with lengthX * lengthY
number of points, is it pretty much impossible to generate shapes with
non-ractangular base with gridded3dset? I guess didn't understand the
documentation very well when it stated that
GriddedSets are N-dimensional sets with rectangular topologies but not
necessarily rectangular geometries.
Thanks in advance.
