NoiseTexture3D
==============

**Inherits:** :ref:`Texture3D<class_Texture3D>` **<** :ref:`Texture<class_Texture>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A 3D texture filled with noise generated by a :ref:`Noise<class_Noise>` object.

.. rst-class:: classref-introduction-group

Description
-----------

Uses the :ref:`FastNoiseLite<class_FastNoiseLite>` library or other noise generators to fill the texture data of your desired size.

The class uses :ref:`Thread<class_Thread>`\ s to generate the texture data internally, so :ref:`Texture3D.get_data<class_Texture3D_method_get_data>` 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:

::

    var texture = NoiseTexture3D.new()
    texture.noise = FastNoiseLite.new()
    await texture.changed
    var data = texture.get_data()

- |void| **set_color_ramp**\ (\ value\: :ref:`Gradient<class_Gradient>`\ )
- :ref:`Gradient<class_Gradient>` **get_color_ramp**\ (\ )

A :ref:`Gradient<class_Gradient>` which is used to map the luminance of each pixel to a color value.

:ref:`int<class_int>` **depth** = ``64`` :ref:`🔗<class_NoiseTexture3D_property_depth>`

.. rst-class:: classref-property-setget

- |void| **set_depth**\ (\ value\: :ref:`int<class_int>`\ )
- :ref:`int<class_int>` **get_depth**\ (\ )

Depth of the generated texture (in pixels).

.. rst-class:: classref-item-separator

----

.. _class_NoiseTexture3D_property_height:

.. rst-class:: classref-property-setget

- |void| **set_height**\ (\ value\: :ref:`int<class_int>`\ )
- :ref:`int<class_int>` **get_height**\ (\ )

Height of the generated texture (in pixels).

----

.. _class_NoiseTexture3D_property_invert:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **invert** = ``false`` :ref:`🔗<class_NoiseTexture3D_property_invert>`

.. rst-class:: classref-property-setget

- |void| **set_invert**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **get_invert**\ (\ )

If ``true``, inverts the noise texture. White becomes black, black becomes white.

.. rst-class:: classref-item-separator

----

.. _class_NoiseTexture3D_property_noise:

.. rst-class:: classref-property

:ref:`Noise<class_Noise>` **noise** :ref:`🔗<class_NoiseTexture3D_property_noise>`

.. rst-class:: classref-property-setget

- |void| **set_noise**\ (\ value\: :ref:`Noise<class_Noise>`\ )
- :ref:`Noise<class_Noise>` **get_noise**\ (\ )

The instance of the :ref:`Noise<class_Noise>` object.

.. rst-class:: classref-item-separator

----

.. _class_NoiseTexture3D_property_normalize:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **normalize** = ``true`` :ref:`🔗<class_NoiseTexture3D_property_normalize>`

.. rst-class:: classref-property-setget

- |void| **set_normalize**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **is_normalized**\ (\ )

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.

.. rst-class:: classref-item-separator

----

.. _class_NoiseTexture3D_property_seamless:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **seamless** = ``false`` :ref:`🔗<class_NoiseTexture3D_property_seamless>`

.. rst-class:: classref-property-setget

- |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_NoiseTexture3D_property_width>`, :ref:`height<class_NoiseTexture3D_property_height>` or :ref:`depth<class_NoiseTexture3D_property_depth>` lower than the default, you may need to increase :ref:`seamless_blend_skirt<class_NoiseTexture3D_property_seamless_blend_skirt>` to make seamless blending more effective.

.. rst-class:: classref-item-separator

----

.. _class_NoiseTexture3D_property_seamless_blend_skirt:

.. rst-class:: classref-property

:ref:`float<class_float>` **seamless_blend_skirt** = ``0.1`` :ref:`🔗<class_NoiseTexture3D_property_seamless_blend_skirt>`

.. rst-class:: classref-property-setget

- |void| **set_seamless_blend_skirt**\ (\ value\: :ref:`float<class_float>`\ )
- :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_NoiseTexture3D_property_width>`, :ref:`height<class_NoiseTexture3D_property_height>` or :ref:`depth<class_NoiseTexture3D_property_depth>` lower than the default, you may need to increase :ref:`seamless_blend_skirt<class_NoiseTexture3D_property_seamless_blend_skirt>` to make seamless blending more effective.

.. _class_NoiseTexture3D_property_width:

.. rst-class:: classref-property

:ref:`int<class_int>` **width** = ``64`` :ref:`🔗<class_NoiseTexture3D_property_width>`

- |void| **set_width**\ (\ value\: :ref:`int<class_int>`\ )
- :ref:`int<class_int>` **get_width**\ (\ )
