Noise Effector

The Noise Effector creates a spatially-varying force field.

• Directional Influence: Outputs a vector that can be plugged into Grow sockets (like Gravity or Phototropism).
• Curl Noise: Supports curl noise for fluid-like, divergence-free turbulence.
• Mappable: Strength and scale can be modulated.

Concept

World-Space Fields Effectors operate in world space. As the plant grows, each internode samples the effector at its current position to determine how much to bend or twist.

Inputs

• Input 0 — Parms (Optional) Connect to the main parameter stream.
• Output — Effector Connect this to an Effector socket on a Grow node.

Parameters

Noise

• Type: Perlin, Simplex, Curl, etc.
• Frequency: Size of the noise features.
• Amplitude: Strength of the force.
• Offset: Animation or spatial offset.

Attributes

Does not consume graph attributes directly (samples position P).

Workflow

1. Create a Noise Effector.
2. Connect it to the Gravity or Phototropism socket of a Grow node.
3. Adjust Frequency and Amplitude to add organic "wiggle" to the growth.
