描述
|
||
----
|
||
|
||
**CompressedTexture3D** 是 :ref:`ImageTexture3D<class_ImageTexture3D>` 的 VRAM 压缩对应物。\ **CompressedTexture3D** 文件的文件扩展名为 ``.ctex3d``\ 。这种文件格式是 Godot 内部使用的；它是通过导入系统导入其他图像格式创建的。
|
||
|
||
\ **CompressedTexture3D** 使用 VRAM 压缩，这可以在渲染纹理时减少 GPU 的内存使用量。这也缩短了加载时间，因为与使用无损压缩的纹理相比，VRAM 压缩的纹理加载速度更快。VRAM 压缩会表现出明显的伪影，并且它旨在用于 3D 渲染，而不是 2D。
|
||
|
||
有关 3D 纹理的一般描述，请参阅 :ref:`Texture3D<class_Texture3D>`\ 。
