Static

Static noise produce a noise function using a static data source, like an array of values, or an existing texture. It can be used to convert a texture to a noise function. The parameters of the static noise defines how the noise is generated when accessing values outside of the source texture.

Node inputs/outputs

The module’s constructor needs:

  • Static Initializer : the data source for the new noise
  • Static Offset :  an offset value that will be used to displace the noise
  • Static Scale : a scaling value that will be used to scale the noise, usually set according to the width and the height of the source texture
  • Static Mode : the generation mode, used when accessing values outside of the texture
  • Static Noise Interpolation : the interpolation strategy, either NEAREST or LINEAR

The output value is a Generation Module

Initializer

There exists two kind of initializers :

  • Texture2DInitializer which takes a 2D texture as an input

 

  • ManualInitializer which takes an array of floats and a width as an input

Examples

The following examples are made using the Texture2DInitializer initialized with a 512×512 texture produced with Sine.

StaticScale = 512.0 512.0, Static Mode = REPEAT

It reproduces exactly the source texture.

StaticScale = 1024.0 512.0, Static Mode = REPEAT

The texture is repeated along the X-axis.

StaticScale = 1024.0 512.0, Static Mode = MIRRORED_REPEAT

The texture is repeated but in a mirrored way along the X-axis

StaticScale = 1024.0 1024.0, Static Mode = MIRRORED_REPEAT

The texture is repeated in a mirrored way along both the X-axis and the Y-axis

StaticScale = 1024.0 1024.0, Static Mode = CLAMP_TO_EDGE

The values outside of the texture comes from the stretched borders of the texture

StaticScale = 1024.0 1024.0, Static Mode = CLAMP_TO_BORDER

The values outside of the texture are equals to 0

StaticOffset = -0.1 -0.1, StaticScale = 1024.0 1024.0, Static Mode = CLAMP_TO_BORDER

Like the previous one, but with an offset.
