Vector Noise ============ .. image:: https://user-images.githubusercontent.com/14288520/189527778-9ece116a-6991-475e-b015-91aa5bbc6995.png :target: https://user-images.githubusercontent.com/14288520/189527778-9ece116a-6991-475e-b015-91aa5bbc6995.png 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).
