Adding a Jumping Jet

A jumping jet is a special type of fountain that emits a
jet of water that appears to be a jumping tube. Jumping jets emit water based on
a timer, meaning that the behavior of the jet can be edited to your
requirements. Multiple jets can be timed together to give the impression that
the water is jumping from one portion of your water garden to another. Jumping
jets can be an impressive addition to your landscape design.
To add a jumping jet:
1.
Click the Add Jumping Jet button that is found near the top of the screen
under the Water Features tab.
2.
Click on your design where you wish to place the jumping jet.
While designing the landscape in the Plan or Perspective
view, jumping jets appear as solid tubes of water. However, when creating a
movie or during a Realtime Walkthrough, the jumping jet sprays animated water
based on the flow rate, angle, and other properties that you have set.
In the picture below, a jumping jet has been added to spray
water into the pond periodically.

Sequencing Jumping Jets
While single jumping jets make good additions to a water
garden design, multiple jumping jets that are timed together can be much more
impressive. By configuring the timing of each jumping jet, the water will appear
to jump from jet to jet during a Realtime Walkthrough. To configure the timing
to be sequential, set the Start delay, the On time,
and the Off time of each jet based on the notes below.
Start delay: The Start
delay of a jumping jet should be set to the sum of the previous jet’s
Start delay, On time, and Travel time. This will ensure that the selected jet
does not start until the previous jet is finished.
On time: The On time can
be set to any amount of time you wish.
Off time: The Off time
should be set to the sum of all previous Travel times and On times, subtracting
the selected jet’s On time. This will ensure that the selected jet remains off
until it is time for it to spray again.
For example, if you placed three jumping jets in your
landscape design that jumped from one jet to the next, the charts below show the
values needed to properly configure the timing.
Jet 1
Property |
Value |
Notes |
Start delay |
0 |
Jet 1 emits water immediately at the beginning of a
Realtime Walkthrough. |
On time |
0.5s |
Jet 1 emits water for one half of a second. |
Off time |
4s |
There are three jets, each of which emit water for one
half of a second and have a Travel time of one second. Using the
above formula, this is 1.5 + 1.5 + 1.5, minus this jet’s On time =
4.5 – 0.5 = 4s. |
Travel time |
1s |
Based on the jet’s Angle (60°) and Flow
rate (50), the water takes one second to travel through the air. This
value is automatically calculated. (We assume one second for this
example.) |
Jet 2
Property |
Value |
Notes |
Start delay |
1.5s |
Jet 2 waits one and a half seconds, which is the time
it takes for jet 1’s water to fully arrive. Using the above formula, this
is 0 (previous jet’s Start delay) + 0.5 (previous jet’s On
time) + 1 (previous jet’s Travel time) = 1.5s. |
On time |
0.5s |
Jet 2 emits water for one half of a second. |
Off time |
4s |
(Same as jet 1). |
Travel time |
1s |
(Same as jet 1). |
Jet 3
Property |
Value |
Notes |
Start delay |
3s |
Jet 3 waits three seconds, which is the time it takes
for jet 1’s water to fully arrive at jet 2, and for jet 2’s water to fully
arrive at jet 3. Using the above formula, this is 1.5 (previous jet’s
Start delay) + 0.5 (previous jet’s On time) + 1 (previous
jet’s Travel time) = 3s. |
On time |
0.5s |
Jet 3 emits water for ½ second. |
Off time |
4s |
(Same as jet 1). |
Travel time |
1s |
(Same as jet 1). |
In the picture below, the three jets used in the
calculations above are shown. Notice how the end of each spray lands on the next
jet nozzle.

In the picture below, the above jumping jets are seen
operating during a Realtime Walkthrough.

Tips:
• If
you wish to create a “pulsing” jumping jet, set the On time and Off time to a
small number, such as 0.2 seconds.
• The
elevation of a jumping jet can be adjusted in order to place it on top of other
objects, such as rocks.
• When
rotating your jumping jet, you may find it convenient to disable Angle snap. For
more information, see Snap Settings and Rotating Objects.
• The
length of a jumping jet’s stream can be adjusted by modifying the jet’s Flow
rate.
• The
jumping jet nozzle is a small model that cannot be changed.
