Reference / Nodes

Modifiers

Float-in, float-out, these are the nodes you wire between a raw value source (a sound band, a time, a knob) and the port it's driving.

Most modifiers are stateless and trivially cheap. The accumulator, delay, smoothing and trigger nodes are the exceptions, they hold per- frame state so the value you read this frame depends on the previous ones.

Sine Wave

sineWaveModifier

Sine oscillator at a chosen frequency, amplitude and phase offset.

Inputs

Port	Type	Default	Range
frequency	float	1	,
amplitude	float	1	,
offset	float	0	,

Outputs

Port	Type	Default	Range	Notes
value	float	,	,

Output runs in [-amplitude, amplitude]; add offset to shift the centre.

Range Remap

rangeRemapModifier

Inputs

Port	Type	Default	Range
value	float	0	,
inMin	float	0	,
inMax	float	1	,
outMin	float	0	,
outMax	float	1	,

Outputs

Port	Type	Default	Range	Notes
result	float	,	,

Same node as in Math & Logic, listed here too because it's the second-most-reached-for modifier after Sine Wave.

Inputs

Port	Type	Default	Range	Notes
bpm	float	120	,

value	float	0	,
smoothUp	float	0.9	,
smoothDown	float	0.9	,

hold	float	0.1	,
release	float	0.3	,

Outputs

Port	Type	Default	Range	Notes
value	float	,	,

Fires a 0→1→0 envelope each time the trigger input crosses 0.5. Useful for one-shot punches off a bass band or a beat detector.

Texture utilities

These operate on texture streams rather than single floats - compositing, feedback, frame timing, and resolution changes. Most of their controls (blend mode, feedback amount, scale factor) live in the inspector; the connectable ports are listed below.

Composite Sources

compositeSourcesModifier

Layers two texture sources with a selectable blend mode and opacity.

Inputs

Port	Type	Default	Range	Notes
background	texture	,	,	Bottom layer. Null = opaque black.
foreground	texture	,	,	Top layer. Null = transparent.
opacity	float	1	0 – 1	Foreground opacity.

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Proper premultiplied alpha-over compositing. The blend mode (Normal, Add, Multiply, Screen, Overlay, Lighten, Darken, Difference) is an inspector field. Use it to stack two finished chains.

Luminance Key

luminanceKeyModifier

Keys out pixels by brightness - a luma key for removing dark or bright areas.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,	Source. Null = transparent black.
low	float	0	0 – 1	Low luminance threshold.
high	float	0.1	0 – 1	High luminance threshold.

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Modulates alpha by a luminance key (Rec. 601 weights). Softness, invert, and key mode (key dark / key bright / keep the range between the thresholds) are inspector fields.

Temporal Filter

temporalFilterModifier

Exponential moving average over frames for motion blur, ghost trails, or temporal denoising.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,
smoothing	float	0.8	,	0 = no trail, 1 = infinite trail.

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Accumulates each frame into a running average. A motion threshold and a fade-to-black option (inspector) let you trail only moving regions or slowly clear the buffer.

Frame Delay

frameDelayModifier

Delays the input by N frames through a ring buffer, for time-offset effects and motion echo.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

The delay length (1–30 frames) is an inspector field. Stack a few at different delays and composite them for a strobing echo trail.

Frame Buffer

frameBufferModifier

Feedback loop that blends the current input with its own previous output for trails and recursive effects.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

The classic feedback primitive. Feedback amount, per-frame decay, and a momentary clear are inspector fields. Insert a transform in the loop for zooming / rotating tunnels.

Downsample

downsampleModifier

Reduces resolution by an integer factor with optional box filtering - for pixelation or blur chains.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,	1/factor the input size.

Factor (2×–16×) and box-filter vs point-sample are inspector fields. Pair with upsample to build cheap blurs.

Upsample

upsampleModifier

Increases resolution by an integer factor with bilinear or nearest filtering.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,	factor × input, capped at 8K.

Factor (2×–8×) and filter mode (bilinear or nearest, for pixel-art scaling) are inspector fields.

Resize

resizeModifier

Resizes the input to a scale factor or an absolute resolution, bilinear or nearest.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,
scaleFactor	float	0.5	0.01 – 4	Used in scale-factor mode.

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Mode (scale factor vs absolute), target width/height, and filter mode are inspector fields. Useful to pin a chain to a fixed working resolution.

Video Null

videoNullModifier

Pass-through node that forwards the input texture unchanged.

Inputs

Port	Type	Default	Range	Notes
texture	texture	,	,

Outputs

Port	Type	Default	Range	Notes
texture	texture	,	,

A no-op for organizing graphs: name a connection point, fan one signal out to several destinations, or leave a reroute handle while debugging. Null input returns transparent black.
