states the distance, in Blender Units, between the topmost part of
two subsequent ripples, and the total Wave effect is given by the
envelope of all the single pulses (<A
HREF="x9097.html#BCD.EFF.F.S68.007"
>Figure 39</A
>).</P
><P
>This has an indirect effect on the ripple amplitude.
Being ripples Gaussian in shape, if the pulses are too next to each
other the envelope could not reach the z=0 quote any more. If this is the
case Blender actually lowers the whole wave so that the minimum is
zero and, consequently, the maximum is lower than the expected amplitude
value, as shown in <A
HREF="x9097.html#BCD.EFF.F.S68.007"

> at the bottom.</P
><P
>The actual width of each Gaussian-like pulse is controlled by
the <TT
CLASS="literal"
>Narrow</TT
> Num Button, the higher the value the narrower the pulse.
The actual width of the area in which the single pulse
is significantly non-zero in Blender Units is given by 4 over
the <TT
CLASS="literal"
>Narrow</TT
> Value. That is, if
<TT
CLASS="literal"
>Narrow</TT
> is 1 the pulse is 4 Units wide,
and if <TT
CLASS="literal"
>Narrow</TT
> is 4 the pulse is 1 Unit Wide.</P
