Vector Noise

This noise node takes a list of Vectors and outputs a list of equal length containing either Vectors or Floats in the range 0.0 to 1.0. The seed value permits you to apply a different noise calculation to identical inputs.

Inputs & Parameters

Parameters	Description
Noise Function	Pick between Scalar and Vector output
Noise Type	Pick between several noise types Blender Cell Noise New Perlin Standard Perlin Voronoi Crackle Voronoi F1 Voronoi F2 Voronoi F2F1 Voronoi F3 Voronoi F4 See mathutils.noise docs ( Noise ) Custom noises: Random Cells Random Gradients Ortho Gradients Numpy Perlin (see examples)
Smooth	Smooth curvature (Only for custom noises)
Interpolate	Gradient interpolation (Hard noise when un-checked) (For custom noises)
Seed	Accepts float values, they are hashed into Integers internally. Seed values of 0 will internally be replaced with a randomly picked constant to allow all seed input to generate repeatable output. (Seed=0 would otherwise generate random values based on system time)
Noise Matrix	Matrix input to determinate noise origin, scale and rotation. One matrix per point can be passed if the matrix list is wrapped

Advanced Parameters

In the N-Panel (and on the right-click menu) you can find:

• Output NumPy: Get NumPy arrays in stead of regular lists (makes the node faster in Scalar mode and in Vector Mode with Custom noises).
