# This example describes a regular 2-dimensional grid. In this example, 
# unlike other examples in this directory, the data are dependent on (in a
# one-to-one correspondence with) the connections component, rather than
# the positions component. Data Explorer interprets this as implying that
# the data value within each connection element is the constant given by
# the corresponding data value. If, for example, you AutoColored and 
# rendered this field, you would see blocks of constant color.
#
# object 1 are the regular positions. The grid is 4x4. The origin is
# at [0 0], and the deltas are 1 in the first dimension, and
# 2 in the second dimension

# object 2 are the regular connections, quads, connecting the positions

# object 3 are the data, which are in a one-to-one correspondence with
