Tip
- Offset and Min
Radius manipulators are both at the center of the handle by
default.
- Adjust Dropoff from
the Channel Box.
To edit wave deformers by using handle
manipulators
- Select the wave deformer node (default
name: waven).
- Select the Show Manipulator Tool (default
shortcut: t key).
- In the scene, select one of the manipulators
on the wave deformer handle.
The manipulators on the
wave deformer handle let you edit attributes.
- -drag
the mouse to edit interactively. Note that the Channel Box updates
the values you are changing.
The Offset and Min
Radius manipulators are both located at the center of the
handle by default.
To edit by moving, rotating or scaling
handle
- Select the wave deformer handle node
(default name: wavenHandle).
- Move (translate), rotate, or scale the
handle to change the effect of the deformation.
- Move or rotate the handle pivot point
by pressing the (Linux and
Windows) or (Mac
OS X) key, moving the pivot point, and then pressing the or key
again.
Remember that you can
access the deformer handle’s local axes (Display > Transform
Display > Local Rotation Axes), rotate and scale pivots
(Display > Transform Display > Rotate
Pivots or Scale Pivots) and selection
handle (Display > Transform Display > Selection
Handle).
To edit waved deformers with the Channel
Box
- Select the wave deformer node (default
name: waven).
One quick way to select
the wave deformer node is to select the object being deformed, and
then select the wave deformer node in its history from the Channel
Box (under INPUTS).
Note that you can control
which attributes are listed as keyable attributes (channels) in
the Channel Box with the Channel
Control editor (select Window > General
Editors > Channel Control).
- Click the name of the channel you want
to edit.
- In your scene, -click
and move the mouse to the left or right. By moving the mouse, you
change the value of the selected channel. As you move the mouse,
note that pressing the key
gives you finer control, and pressing the key
gives you less control.
To edit wave deformers with the Attribute
Editor
- Select the wave deformer node (default
name: waven).
- Open the Attribute Editor by
selecting
Window > Attribute Editor or
use the default shortcut +a.
- Edit the attributes.
See
wave.
To delete a wave deformer
- Select the wave deformer handle.
- Select
Edit > Delete or
us the default shortcut (Linux
and Windows) or (Mac
OS X) key.
The wave deformer handle,
wave deformer handle shape, and wave deformer nodes are all deleted.
However, the object still has the tweak node as an input node, so
any tweaks you might have made are preserved. Also, note that the
various input nodes that structure the evaluation of the deformation
are not deleted.
Wave deformer example
Ripple animation
You
can create ripple effects by using a wave deformer on a NURBS or
polygonal surface. This example shows how you can create a simple
ripple effect on a NURBS plane.
To create the NURBS plane
- Create a NURBS plane, using the default
creation options except set Width to
20, U Patches to 40, and V
Patches to 40.
To create a wave deformer
- With the plane selected, create a wave
deformer for the plane with the following creation options:
- Min Radius
-
- Max Radius
-
- Amplitude
-
- Wavelength
-
- Dropoff
-
- Offset
-
The result follows:
Next, you will set keys
at frames 1, 10, and 20.
To key ripple at frame 1
- In the Time Slider,
select frame 1.
- In the Channel Box,
set wave1’s attributes as follows:
- Amplitude
-
- Max Radius
-
- Set keys for all of wave1’s attributes.
To key ripple at frame 10
- In the Time Slider,
select frame 10.
- In the Channel Box,
set wave1’s attributes as follows:
- Amplitude:
-0.2 (negative value allows first wavelet to go down)
- Dropoff Position:
0.5
- Max Radius:
1
The result is as follows:
- Set keys for all of wave1’s attributes.
To key ripple at frame 20
- In the Time Slider,
select frame 20.
- In the Channel Box,
set wave1’s attributes as follows:
- Min Radius:
1
- Amplitude:
-0.1
The result is as follows:
- Set keys for all of wave1’s attributes.
To see the ripple
- Scrub or play the animation.
- You can create more intricate and complicated
rippling effects by continuing to adjust the wave deformer’s attributes.
You can also apply additional wave or sine deformers to the plane
for more complex results.
TipInstead of animating
the
Dropoff Position attribute,
you could write an expression that drives the drop off of the wave.
The expression would be as follows:
wave1.offset
= wave1.wavelength * .25;
