Waveform Falloff

falloffs/waveform-falloff·v1.5.1

IN:1 OUT:1

SUMMARY

Waveform Falloff runs a sine, square, triangle or sawtooth wave along a per-point driver: an attribute, the point index, the distance to a center for rings, or the position along an axis for bands. Frequency, Phase, Range, Amplitude and Offset shape the wave, Normalize Driver makes Frequency the number of cycles across the whole geometry, and Use Rest Attribute keeps the pattern fixed on deforming geometry.

Time Varying moves the wave at Speed cycles per second, and Fade ramps it in or out over time, optionally looping, for pulses and reveals. The shared remap, combine and preview controls match the rest of the falloff family, and chaining several Waveform Falloffs with Add or Multiply composes more complex waves.

PARAMETERS

PAGEWaveform

Group	Group	If there are input groups, specifying a group name in this field will cause this POP to act only upon the group specified.
[+]Driver	Driver	Selects the per-point value the waveform runs along.
[+]Input Attribute	Inputattr	The point attribute the wave runs along when Driver is Attribute. A component such as P(1) is allowed.
Use Rest Attribute	Userestattr	Enable sampling the noise at the rest position, which keeps it stable under deformation.
[+]Center	Center	The point the distance or the axis position is measured from.
[+]Axis	Axis	The direction the position is measured along.
Normalize Driver	Normalizedriver	Fits the driver to the 0 to 1 range over all points, so Frequency is the number of cycles across the geometry.
[+]Waveform	Waveform	Selects the shape of the wave.
Pulse Width	Pulsewidth	The part of each cycle the square wave is high, from 0 to 1.
Frequency	Frequency	The number of cycles per unit of the driver.
Phase	Phase	Offsets the wave along the driver, in cycles.
[+]Range	Range	Selects the range of the wave before Amplitude and Offset.
Amplitude	Amp	The noise values amplitude (a scale on the values output).
Offset	Offset	Adds an offset to the resulting value.

PAGETime

Time Varying	Timevarying	Enable moving the wave over time.
[+]Time Source	Timesource	Selects the clock the wave and the fade follow. Absolute Time keeps running when the timeline loops or pauses.
Speed	Speed	The number of cycles the wave moves per second.
[+]Fade	Fade	Fades the wave in or out over time, toward Offset.
Restart Fade	Restartfade	Starts the fade again from now.
Fade Start	Fadestart	The delay from the start of the fade, in seconds. The fade starts when Fade is changed or Restart Fade is pulsed.
Fade Length	Fadelength	The duration of the fade, in seconds.
Loop Fade	Loopfade	Enable repeating the fade.
Loop Length	Looplength	The time between the starts of two fades, in seconds.

PAGEFalloff

[+]Combine Operation	Combineop	Specify how to combine this falloff with the existing falloff value.
Combine Falloff Attribute	Combattrscope	Sets the existing falloff attribute to combine with.
Swap Operation Order	Swaporder	Swaps the order of the operands. A operation B is changed to B operation A.
Combine Strength	Combstrength	Sets the blend of the combine operation, from 0 to 1.
Output Falloff Attribute	Outputfalloffattr	Name of the attribute the falloff is written to.
Preview Falloff	Previewfalloff	Enable coloring the points by the falloff.
[+]Falloff Ramp	Fallofframp	Selects the color ramp of the preview.
Open Custom Ramp Editor	Opencustomrampeditor	Open the editor of the custom preview ramp.
Reset Custom Ramp	Resetcustomramp	Resets the custom preview ramp.

PAGERemap

Enable Remap	Remap	Enable the remap controls.
Clamp	Clamp	Clamps the falloff values to the 0-1 range.
Fit	Fit	Enable fitting the values from the input range to the output range.
Auto Input Min Max	Auto	When on, the actual minimum and maximum values are used as the input range.
Input Min	Inputmin	Sets the minimum of the input range.
Input Max	Inputmax	Sets the maximum of the input range.
Output Min	Outputmin	Sets the minimum of the output range.
Output Max	Outputmax	Sets the maximum of the output range.
Invert	Invert	Invert the falloff, outputting 1 minus the value.
Enable Ramp Remap	Enablerampremap	Enable remapping the falloff through a ramp.
Open Ramp Editor	Openrampeditor	Opens the remap ramp editor.
Reset Ramp	Resetramp	Resets the remap ramp.
Custom Ramp TOP	Customramptop	Reference to a TOP used as the remap ramp, overriding the ramp editor.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
Render Primitives	Renderprimitives	Whether to render the full POPX geometry. When off, only point instances are drawn.
Convert to Point Primitives	Converttoptprim	Enable converting points to point primitives when Render Primitives is off.
SRT / RST	Srtrst	Sets the transform order, SRT or RST, used when the points are rendered as TouchDesigner instances.
