Noise Displace ============== .. image:: https://user-images.githubusercontent.com/14288520/194018662-8f0712a7-c99b-4b89-b153-e52f25f8db1a.png :target: https://user-images.githubusercontent.com/14288520/194018662-8f0712a7-c99b-4b89-b153-e52f25f8db1a.png This noise node displaces a list of Vectors. The seed value permits you to apply a different noise calculation to identical inputs. Inputs & Parameters ------------------- +----------------+-------------------------------------------------------------------------+ | Parameters | Description | +================+=========================================================================+ | Mode | Pick between Scalar along Normal and Vector output | +----------------+-------------------------------------------------------------------------+ | Noise Type | Pick between several noise types | | | Mathutils noise: | | | | | | - 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) | +----------------+-------------------------------------------------------------------------+ | Scale Out | Vector to multiply the added vector | +----------------+-------------------------------------------------------------------------+ | Noise Matrix | Matrix input to determinate noise origin, scale and rotation | +----------------+-------------------------------------------------------------------------+ Advanced Parameters ------------------- In the N-Panel (and on the right-click menu) you can find: * **List Match**: Define how list with different lengths should be matched. * **Output NumPy**: Get NumPy arrays in stead of regular lists (makes the node faster with Custom noises slower with Mathutils noises).

seeds. .. image:: https://user-images.githubusercontent.com/14288520/193941010-19f17070-a69a-4988-8492-fcde1d182bf4.png :target:

Struct-> :doc:`List Split ` * Viz-> :doc:`Viewer Draw ` --------- For the Mathutils Noises: Seed and scale per vertex can be passed, in this example the seed is chosen by determining the closest point of another mesh and the scale is based on the distance to that point. .. image:: https://user-images.githubusercontent.com/14288520/193999641-adb31774-0c64-4189-86b6-cb9ff14f6db1.png :target:

--------- For the custom noises: The custom noises will only allow one seed and matrix per object but they offer two different interpolations per noise to change the noise look. .. image::
