control over the precise direction of the blur, use the Directional
Blur effect.
The nature of the Box Blur effect creates the most unique
results when isolating the blur to a specifi c dimension. In Fig.
4.15, I took the Blur Radius value to 30, left the default Iterations
value at 1, and changed the Blur Dimensions drop down to
Horizontal. This only creates blur along the X-axis (left and right).
If we changed the Blur Dimensions value to Vertical, the blur
would be along the Y-axis (up and down). Again, notice the way
that the Box Blur effect makes a boxy blur. This causes the edges
of the star to overlap, creating new geometric patterns. You could
