3D Modifiers & Effects

Geometry modifiers wire geometry-in, geometry-out, chain them to deform a single primitive into something interesting. Plus a particle emitter and the audio analyzer.

The four geometry modifiers run as Metal compute kernels against the upstream vertex / index buffers, so chaining is cheap. The instancer replicates input geometry into many transforms in a single pass.

Noise Displace 3D

noiseDisplace3d3D / Modifiers

Displaces vertices along their normals using animated FBM noise.

Inputs

Port	Type	Default	Range
geometry	geometry	,	,
strength	float	0.5	,
frequency	float	2	,
octaves	float	3	,
speed	float	1	,

Outputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,

Best on dense meshes, a 64-segment sphere or a high-segment torus. Octaves above 4 stop adding visible detail. Animate strength from a sound band for breathing objects.

Twist 3D

twist3d3D / Modifiers

Twists geometry around an axis (X, Y or Z) by a chosen angle, centred at a position with a falloff height.

Inputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,
angle	float	90	,	Total twist in degrees across the falloff height.
axis	float	1	,	0 = X, 1 = Y, 2 = Z.
centerY	float	0	,
height	float	2	,

Outputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,

Wave 3D

wave3d3D / Modifiers

Sine-wave displacement of vertex positions along a chosen displace axis, with a chosen propagation axis.

Inputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,
amplitude	float	0.3	,
frequency	float	4	,
speed	float	2	,
axis	float	0	,	Propagation axis: 0 = X, 1 = Y, 2 = Z.
displaceAxis	float	1	,	Which axis to push vertices along: 0 = X, 1 = Y, 2 = Z.

Outputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,

Reads as flag, water surface or pulsing tube depending on the axis pairing. Set propagation = X and displace = Y for the classic flag wave on a plane.

Instancer 3D

instancer3d3D / Modifiers

Replicates one geometry into N instances arranged linearly, radially or on a grid.

Inputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,
count	float	8	,
mode	float	0	,	0 = linear, 1 = radial, 2 = grid.
offsetX	float	1.5	,
offsetY	float	0	,
offsetZ	float	0	,
rotateStep	float	0	,
scaleStep	float	1	,
radius	float	3	,	Used only in radial mode.

Outputs

Port	Type	Default	Range	Notes
geometry	geometry	,	,

Cheap, instances share their vertex buffer and only the per- instance transform varies. Use linear mode for a row, radial mode for a clock-face arrangement, grid mode for a regular tiling.

Particle Emitter 3D

particleEmitter3d3D / Effects

GPU particle emitter, outputs a particles port for connection into a Scene 3D's particle slot.

Inputs

Port	Type	Default	Range	Notes
emitRate	float	200	,	Particles per second.
lifetime	float	2	,
speed	float	3	,
speedVariance	float	0.5	,
spreadAngle	float	0.5	,
sizeStart	float	0.15	,
sizeEnd	float	0.02	,
gravity	float	-2	,
drag	float	0.3	,
turbulence	float	1	,
colorStart	color	1, 0.6, 0.2, 1	,
colorEnd	color	1, 0.1, 0, 0	,

Outputs

Port	Type	Default	Range	Notes
particles	particles	,	,

Emission point and direction follow the node's transform. Defaults read as warm sparks falling under gravity, drop the gravity value and bump turbulence for a floating-dust look, or push speed and spread for an explosion.

Audio Analyzer

audioAnalyzer3D / Effects

System-wide audio reactivity, outputs bass / mids / highs / volume / peak floats from the live audio device.

Inputs

Port	Type	Default	Range
bassMultiplier	float	1	,
midsMultiplier	float	1	,
highsMultiplier	float	1	,
volumeMultiplier	float	1	,

Outputs

Port	Type	Default	Range
bass	float	,	,
mids	float	,	,
highs	float	,	,
volume	float	,	,
peak	float	,	,

The simpler cousin of soundLoader + soundModifier. Listens to the live audio input the OS hands to R3NE; emits one float per band already smoothed and ready to drive a port.

Macs route system audio differently to capture. To pick up your DJ software, route its output via BlackHole or a similar virtual audio device and pick that as the system input.
