Knot

generators/knot·v1.5.1
IN:0  OUT:1

Knot traces a closed knot: a Torus Knot set by P and Q, the Trefoil, the Figure Eight, a Lissajous knot from per-axis Frequency and Phase, or a Spherical knot. Height and Ripple reshape it along its length.

Output Curve gives one closed line strip, Surface a tube with Thickness, Flatten and Pulse, and Points one framed point per segment with Orient, Up and Scale for instancing along the knot. Twist turns the frame, and animating Offset makes the twist, pulse and KnotU flow along the knot.

PAGEKnot
PPHow many times the knot turns around the Y axis.
QQSets how many times the knot passes through the hole (Torus Knot) or waves up and down (Spherical). P and Q with no common factor give one knot.
FrequencyFreqThe Lissajous frequencies in X, Y and Z: whole numbers with no common factor give a knot.
PhasePhaseThe Lissajous phases in X, Y and Z, in degrees.
RadiusRadiusThe size of the knot.
Minor RadiusMinorradiusSets the radius of the torus the Torus Knot winds around. For Spherical, how far the knot waves from the equator, up to Radius at the poles.
HeightHeightScales the knot along Y: 0 flattens it into the XZ plane.
RippleRippleSwells and pinches the knot in XZ along its length.
Ripple FrequencyRipplefreqThe number of swells around the knot.
SegmentsSegmentsThe number of points along the knot.
SidesSidesThe number of points around the tube.
ThicknessThicknessThe radius of the tube, and Scale for Points.
FlattenFlattenSets the tube cross section. 1 is round, 0 is a flat ribbon.
TwistTwistThe number of turns of the cross section, Up and Orient along the knot. It is rounded to whole turns so the loop stays closed.
PulsePulseSwells and thins the tube (and Scale for Points) along the knot.
Pulse FrequencyPulsefreqThe number of swells along the knot.
OffsetOffsetSlides the Twist, the Pulse and KnotU along the knot: animate it to make them flow.
