VSinOsc

See also: SinOsc

Description

VSinOsc, just like the audio UGen SinOsc UGen, is a sinusoidal oscillator. It can process inputs of one to four dimensions and produces an output in the same dimension. The arguments parallel the arguments used by SinOsc , with the only difference being that the default mul and add argument values are modified to support producing a sin output range within [0, 1] instead of the audio range [-1, 1].

Supported Rates: frame, shape, pixel

Class Methods

VSinOsc.fr(freq: 1.0, phase: 0.0, mul: 0.5, add: 0.5)

VSinOsc.sr(freq: 1.0, phase: 0.0, mul: 0.5, add: 0.5)

VSinOsc.pr(freq: 1.0, phase: 0.0, mul: 0.5, add: 0.5)

Make a VSinOsc VGen at requested rate.

Arguments

freq

Oscillator frequency in cycles per second or Hz.

phase

Oscillator phase in radians.

mul

Multiplier to apply to oscillator output.

add

Value to add to oscillator output after multiply.

Dimensions

Examples

(
// This example demonstrates using the three-dimensional
// VSinOsc to produce separate red, green, and blue
// channel outputs. Note that all arguments have to be
// provided to the higher dimensional VSinOsc instances,
// because the defaults are only 1-dimensional, and
// Scintillator currently can't "autosplat" defaults to
// higher-dimensional arguments.

    VRGBOut.pr(VX.pr(rgb), VY.pr(rgb), VZ.pr(rgb));
