# White Noise Texture Node

Nota

This node is ported from shader nodes. The manual and images are
referencing the shader version of the node.
This node accepts field inputs and outputs.
When not connected the Vector input has an implicit `position`

attribute value.

The *White Noise Texture* node returns a random number based on an input Seed.
The seed can be a number, a 2D vector, a 3D vector, or a 4D vector; depending on the *Dimensions* property.
The output number ranges between zero and one.

## Ingressi

The inputs are dynamic, they become available if needed depending on the node properties.

- Vector
Vector used as seed in 2D, 3D, and 4D dimensions.

- W
Value used as seed in 1D and 4D dimensions.

## Proprietà

- Dimensions
The dimensions of the space to evaluate the noise in.

- 1D:
The

*W*input is used as seed.- 2D:
The X and Y components of the

*Vector*input are used as seed.- 3D:
The

*Vector*input is used as seed.- 4D:
Both the

*Vector*input and the*W*input are used as seed.

## Uscite

- Valore
Output random value.

- Colore
Output random color.

## Note

The slightest difference in seed values would result in completely different outputs. Consequently, bad precision may have significant impact on the output. Usually, we can mitigate this issue by:

Eliminating the problematic seed value. If the problematic seed value is constant, it should be eliminated by choosing a lower dimension or multiplying it by zero.

Adding an arbitrary value to the seed. The issue might only happen at certain boundaries, like unit boundaries, so simply adding an arbitrary value might solve the issue.

Taking the absolute value of the seed. In computing, zero may be positive or negative, so taking the absolute values unifies the zero into a single value.
