==============

|
|
A 2D texture filled with noise generated by a :ref:`Noise<class_Noise>` object.

Description
|
|
-----------
|
|
|
|
Uses the :ref:`FastNoiseLite<class_FastNoiseLite>` library or other noise generators to fill the texture data of your desired size. **NoiseTexture2D** can also generate normal map textures.
|
|
|
|
The class uses :ref:`Thread<class_Thread>`\ s to generate the texture data internally, so :ref:`Texture2D.get_image()<class_Texture2D_method_get_image>` may return ``null`` if the generation process has not completed yet. In that case, you need to wait for the texture to be generated before accessing the image and the generated byte data:
|
|
|
|
::
|
|
|
|
var texture = NoiseTexture2D.new()
|
|
texture.noise = FastNoiseLite.new()
|
|
await texture.changed
|
|
var image = texture.get_image()
|
|
var data = image.get_data()

Determines whether mipmaps are generated for this texture. Enabling this results in less texture aliasing in the distance, at the cost of increasing memory usage by roughly 33% and making the noise texture generation take longer.
|
|
|
|
\ **Note:** :ref:`generate_mipmaps<class_NoiseTexture2D_property_generate_mipmaps>` requires mipmap filtering to be enabled on the material using the **NoiseTexture2D** to have an effect.

|
|
|
|
If ``true``, the noise image coming from the noise generator is normalized to the range ``0.0`` to ``1.0``.
|
|
|
|
Turning normalization off can affect the contrast and allows you to generate non repeating tileable noise textures.

- |void| **set_seamless**\ (\ value\: :ref:`bool<class_bool>`\ )
|
|
- :ref:`bool<class_bool>` **get_seamless**\ (\ )
|
|
|
|
If ``true``, a seamless texture is requested from the :ref:`Noise<class_Noise>` resource.
|
|
|
|
\ **Note:** Seamless noise textures may take longer to generate and/or can have a lower contrast compared to non-seamless noise depending on the used :ref:`Noise<class_Noise>` resource. This is because some implementations use higher dimensions for generating seamless noise.
|
|
|
|
\ **Note:** The default :ref:`FastNoiseLite<class_FastNoiseLite>` implementation uses the fallback path for seamless generation. If using a :ref:`width<class_NoiseTexture2D_property_width>` or :ref:`height<class_NoiseTexture2D_property_height>` lower than the default, you may need to increase :ref:`seamless_blend_skirt<class_NoiseTexture2D_property_seamless_blend_skirt>` to make seamless blending more effective.

- :ref:`float<class_float>` **get_seamless_blend_skirt**\ (\ )
|
|
|
|
Used for the default/fallback implementation of the seamless texture generation. It determines the distance over which the seams are blended. High values may result in less details and contrast. See :ref:`Noise<class_Noise>` for further details.
|
|
|
|
\ **Note:** If using a :ref:`width<class_NoiseTexture2D_property_width>` or :ref:`height<class_NoiseTexture2D_property_height>` lower than the default, you may need to increase :ref:`seamless_blend_skirt<class_NoiseTexture2D_property_seamless_blend_skirt>` to make seamless blending more effective.
