Waveform surface node

Creates a waveform shape out of surface geometry

This operator is used to generate a wave shape oriented in the XZ-plane. The orientation and shape of the wave can be controlled directly, while the waveform’s resolution corresponds to the detail of the geometry to which it is applied.

A wave created by this operator can be used to create a moving wave in a Particle Fluid. To make this possible, enable Output Wave Velocity Attributes and perform a Finalize Waves operation on the object containing the wave.

Parameters

Height

The height of the wave.

Wavelength

The length of the wave, relative to the height.

Width

The distance from the center along the wave axis the wave will be applied

Gravity

The gravity that the wave will be subjected to.

Position

The center of the waveform.

Rotation

The orientation of the waveform in the XZ-plane.

Output Wave Velocity Attributes

Enabling this option will allow a subsequent Finalize Waves operator to properly given particle velocities to points inside the wave. NOTE

If this Waveform will be part of a Particle Fluid object, this option should be enabled, and a Finalize Waves operator should be used before the creation of the Particle Fluid.

Falloff Type

Controls how the wave decreases in intensity the farther the surface gets from the wave center.

None

The wave is the same intensity, regardless of how far away it is from the wave center.

Linear

A linear falloff of intensity of the wave between the minimum and maximum distances from the wave center.

Quadratic

This is a general form of falloff. Three coefficients are specified to create a quadratic equation.

C = Constant coefficient L = Linear coefficient Q = Quadratic coefficient

The mathematics of this model are represented by

Cl = 1 / ( C + L*D + Q*D*D)

Min

Mininum distance from the wave center to start the falloff.

Max

Maximum distance from the wave center to falloff to.

Constant Coefficient

C in the falloff formula (see above).

Linear Coefficient

L in the falloff formula (see above).

Quadratic Coefficient

Q in the falloff formula (see above).
