row

<row> creates a row structure by arranging all the children objects into a "row" along the x axis.

The first child remains at the same position. The rest of the children are re-positioned in such a way that each child is next to the previous child along the x axis.

In terms of alignment, all objects are aligned to the middle along the y axis and aligned to the min along the z axis. A spacing attribute can be optionally provided to specify how much space to add between every two objects.

In the example below, three cubes of varying sizes are grouped into a row along the x axis, automatically aligned along the other two axes, and have a spacing of 5 between every two cubes.
