Interference effect: overlaid moving waves distorting the field.

Author: ldirko & blazoncek (WLED port), https://editor.soulmatelights.com/gallery/1089-distorsion-waves , via the predecessor, https://github.com/ewowi/MoonLight/blob/main/src/MoonLight/Nodes/Effects/E_WLED.h

Two sine waves whose summed value drives the hue, giving a flowing moire field. They run at independent frequencies and slightly different time rates, so they beat.

Prior art: WLED's Distortion Waves, by way of MoonLight.

Public Attributes

uint8_t freq_x = 3 : The horizontal wave's frequency.

uint8_t freq_y = 3 : The vertical wave's frequency.

uint8_t speed = 50 : How fast the field moves, where 0 freezes it.

Public Methods

virtual inline const char * tags() const override : Catalog tags: MoonLight and WLED origin.

virtual inline Dim dimensions() const override : A plane, which extrude lifts through a volume.

virtual inline void defineControls() override : Publish both wave frequencies and the speed.

virtual inline void tick() override : Sum the two waves per pixel and read the palette at their average.

More info

Integer throughout

Angles are bytes and the sines return bytes, which the effect averages into a hue. The vertical wave's time runs about 1.3 times the horizontal, approximated in integers. That hue then indexes the active palette, where the source swept hue directly.
