Perlin noise node
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
The Perlin noise node outputs a texture generated as a sum of Perlin noise functions
|
|
with increasing frequencies and decreasing amplitudes.

Inputs
|
|
++++++
|
|
|
|
The Perlin noise node does not accept any input.
|
|
|
|
Outputs
|
|
+++++++
|
|
|
|
The Perlin noise node provides a greyscale Perlin noise texture.

Parameters
|
|
++++++++++
|
|
|
|
The Perlin noise node accepts the following parameters:
|
|
|
|
* *Scale X* and *Scale Y* are the subdivisions of the first iteration
|
|
|
|
* *Iterations* is the number of iterations
|
|
|
|
* *Persistance* is the ratio between the amplitude of subsequent iterations. Lower values
|
|
of persistance generate smoother textures.
|
|
|
|
Notes
|
|
+++++
|
|
|
|
As with all random nodes, the seed is held by the node's position, so moving the node in the graph
|
|
will modify the texture, and the outputs will remain the same if its position and parameters
|
|
are not changed.
