VSaw

See also: LFSaw

Description

Similar to its analog sibling LFSaw the VSaw is a video sawtooth 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 LFSaw , although the output is configured to range from [0, 1].

dimensions

Arguments

freq

Oscillator frequency in cycles per second or Hz.

phase

Oscillator phase in radians.

Examples

// This example represents some of the early origins of the Scintillator logo.
// It uses a VSaw to generate the bands. Each pixel on the screen is oscillating
// at 5 Hz, but the phase changes as a function of distance from the center of
// the screen. This smooth variation in phase causes the bands to appear to
// move outward over time.
