由 :ref:`Noise<class_Noise>` 物件生成的雜訊所填充的紋理。

說明
|
|
----
|
|
|
|
使用 :ref:`FastNoiseLite<class_FastNoiseLite>` 或其他庫來填充所需大小的紋理資料。
|
|
|
|
該類在內部使用 :ref:`Thread<class_Thread>` 生成紋理資料，因此如果生成過程尚未完成，\ :ref:`Texture2D.get_image()<class_Texture2D_method_get_image>` 可能會返回 ``null``\ 。在這種情況下，需要等待紋理生成後再存取圖像和生成的位元組資料：
|
|
|
|
::
|
|
|
|
var texture = NoiseTexture3D.new()
|
|
texture.noise = FastNoiseLite.new()
|
|
await texture.changed
|
|
var data = texture.get_data()

如果為 ``true``\ ，來自雜訊產生器的雜訊圖像，將被正規化到範圍 ``0.0`` 到 ``1.0``\ 。
|
|
|
|
關閉正規化會影響對比度，並允許生成非重複的可平鋪雜訊紋理。

如果為 ``true``\ ，則從 :ref:`Noise<class_Noise>` 資源請求無縫紋理。
|
|
|
|
\ **注意：**\ 與非無縫雜訊相比，無縫雜訊紋理可能需要更長的時間來生成，並且/或者可能具有較低的對比度，具體取決於所使用的 :ref:`Noise<class_Noise>` 資源。這是因為一些實作使用更高的維度來生成無縫雜訊。
|
|
|
|
\ **注意：**\ 預設的 :ref:`FastNoiseLite<class_FastNoiseLite>` 實作在生成無縫紋理時使用退回路徑。如果使用的 :ref:`width<class_NoiseTexture3D_property_width>`\ 、\ :ref:`height<class_NoiseTexture3D_property_height>` 或 :ref:`depth<class_NoiseTexture3D_property_depth>` 小於預設值，你可能需要通過增大 :ref:`seamless_blend_skirt<class_NoiseTexture3D_property_seamless_blend_skirt>` 來讓無縫混合更高效。
