Type Range/options Description
WaveControls float2 0.0 – 1.0 Defines the oscillation of the wave.
WaveCenter float2 0.0 – 1.0 The image coordinates of the origin of the ripple waves.
Frequency float 1.0 – 10.0 The frequency of the ripple waves.
Speed float 1.0 – 50.0 The speed of the ripple waves.
Height float 0.0 – 1.0 The height of each ripple wave.
Point float 0.0 – 1.0 The point within the duration of the effect at which the enclosing element will have the specified value. When the time attribute is equal to 0.0, it indicates the starting point of the clip; when the time attribute is equal to 1.0, it indicates the end point of the clip.
