处理 3D 纹理的类，使用此类可创建 3D texture assets。
3D 纹理通常用作着色器的查找表，或用于表示体积数据。
通常您会创建一个 3D 纹理，将其填满数据（SetPixels 或 SetPixels32），然后调用
Apply，以便将这些数据上传到 GPU。
| depth | 纹理深度（只读）。 |
| format | 纹理中像素数据的格式（只读）。 |
| isReadable | Returns true if this 3D texture is Read/Write Enabled; otherwise returns false. For dynamic textures created from script, always returns true. |
| Texture3D | 创建一个新的空 3D 纹理。 |
| Apply | 实际应用先前的全部 SetPixels 更改。 |
| GetPixels | 返回表示一个 Mip 级别 3D 纹理的像素颜色数组。 |
| GetPixels32 | 返回表示一个 Mip 级别 3D 纹理的像素颜色数组。 |
| SetPixels | 设置 3D 纹理的像素颜色。 |
| SetPixels32 | 设置 3D 纹理的像素颜色。 |
| currentTextureMemory | The amount of memory currently being used by textures. |
| desiredTextureMemory | This amount of texture memory would be used before the texture streaming budget is applied. |
| nonStreamingTextureCount | Number of non-streaming textures. |
| nonStreamingTextureMemory | Total amount of memory being used by non-streaming textures. |
| streamingMipmapUploadCount | How many times has a texture been uploaded due to texture mipmap streaming. |
| streamingRendererCount | Number of renderers registered with the texture streaming system. |
| streamingTextureCount | Number of streaming textures. |
| streamingTextureDiscardUnusedMips | Force the streaming texture system to discard all unused mipmaps immediately, rather than caching them until the texture memory budget is exceeded. |
| streamingTextureForceLoadAll | Force streaming textures to load all mipmap levels. |
| streamingTextureLoadingCount | Number of streaming textures with mipmaps currently loading. |
| streamingTexturePendingLoadCount | Number of streaming textures with outstanding mipmaps to be loaded. |
| targetTextureMemory | The amount of memory used by textures after the mipmap streaming and budget are applied and loading is complete. |
| totalTextureMemory | The total amount of memory that would be used by all textures at mipmap level 0. |
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | 对象的名称。 |
| anisoLevel | 纹理的各向异性过滤级别。 |
| dimension | 纹理的维度（类型）（只读）。 |
| filterMode | 纹理的过滤模式。 |
| height | 纹理的高度（以像素为单位）。（只读） |
| imageContentsHash | 纹理的哈希值。 |
| isReadable | Returns true if the Read/Write Enabled checkbox was checked when the texture was imported; otherwise returns false. For a dynamic Texture created from script, always returns true. For additional information, see TextureImporter.isReadable. |
| mipMapBias | 纹理的多级渐进纹理偏差。 |
| updateCount | 更新纹理时，此计数器会递增。 |
| width | 纹理的宽度（以像素为单位）。（只读） |
| wrapMode | 纹理坐标换行模式。 |
| wrapModeU | 纹理 U 坐标换行模式。 |
| wrapModeV | 纹理 V 坐标换行模式。 |
| wrapModeW | Texture3D 的纹理 W 坐标换行模式。 |
| GetInstanceID | 返回对象的实例 ID。 |
| ToString | 返回 GameObject 的名称。 |
| GetNativeTexturePtr | 获取指向纹理资源的原生（底层图形 API）指针。 |
| IncrementUpdateCount | 递增更新计数器。 |
| Destroy | 删除 GameObject、组件或资源。 |
| DestroyImmediate | 立即销毁对象 /obj/。强烈建议您改用 Destroy。 |
| DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. |
| FindObjectOfType | 返回第一个类型为 type 的已加载的激活对象。 |
| FindObjectsOfType | 返回所有类型为 type 的已加载的激活对象的列表。 |
| Instantiate | 克隆 original 对象并返回克隆对象。 |
| SetGlobalAnisotropicFilteringLimits | 设置各向异性限制。 |
| SetStreamingTextureMaterialDebugProperties | Uploads additional debug information to materials using textures set to stream mip maps. |
| bool | 该对象是否存在？ |
| operator != | 比较两个对象是否引用不同的对象。 |
| operator == | 比较两个对象引用，判断它们是否引用同一个对象。 |
