Moving the mouse rotates the camera view. * **默认模式(视角漫游):** 光标**隐藏**。移动鼠标可以旋转视角。 * **UI Cursor Mode (Press TAB):** * **Press `TAB` key** to toggle mode. * The cursor becomes **visible**, and camera rotation **stops**. * Use this mode to click buttons or drag sliders on the UI. * **UI 交互模式(按 TAB 键):** * **按 `TAB` 键** 切换模式。 * 光标**显示**,视角旋转**锁定**。 * 在此模式下,您可以点击按钮或拖拽调整 UI 参数。 ### Movement Keys / 移动按键 * **`W / S / A / D`**: Move Forward / Backward / Left / Right (前后左右移动) * **`Q / E`**: Move Down / Up (垂直升降) * **`Shift` (Hold)**: Boost movement speed (按住加速移动) ## Features / 功能特性 * **Real-time Preview:** Visualize 3D noise directly in the Unity Editor before exporting. * **实时预览:** 在导出前直接在编辑器中查看 3D 噪声的体积渲染效果。 * **Composite Noise Generation:** * **复合噪声生成:** * **R Channel:** Perlin-Worley noise (Base cloud shape). (R 通道:Perlin-Worley 噪声,用于云的基础形状) * **G Channel:** High-frequency Worley noise (Edge details). (G 通道:高频 Worley 噪声,用于边缘侵蚀细节) * **Format Support:** * **多格式支持:** * **DDS (Volume Texture):** Supports BC6H (HDR) and BC7 compression. (支持 BC6H HDR 和 BC7 压缩格式) * **PNG/EXR:** Exports slices for debugging or external processing. (支持导出切片序列,便于调试或外部处理) * **Automated Dependency Management:** * **全自动依赖管理:** * Automatically downloads Microsoft **DirectXTex** tools (`texconv`, `texassemble`)(自动下载微软 **DirectXTex** 工具链) --- ## Usage Workflow (Important!) / 使用流程(重要!) 1. **Initialize / 初始化:** **Click the "Generate Noise" button first.** **首先点击 "Generate Noise" 按钮。** > *Note: Parameters are locked and export is disabled until the initial noise is generated.* > *注意:在生成初始噪声之前,所有参数均被锁定,且无法导出文件。* 2. **Tweak & Preview / 调整与预览:** Once generated, you can adjust sliders in real-time to see changes in the preview window. 生成完毕后,你可以实时拖动滑块调整参数,并在预览窗口即时查看体积云的变化。 3. **Export / 导出:** Click **"Export as DDS"** to generate the final `.dds` volume texture. 点击 **"Export as DDS"** 导出最终的 `.dds` 体积纹理文件。 --- ## Parameters Explained / 参数详解 ### 1. Noise Generation (噪声生成) * **Resolution (分辨率):** * The resolution of the 3D texture (e.g., 64x64x64). Higher values provide more detail but consume more memory and processing time. * 3D 纹理的分辨率(如 64x64x64)。数值越高细节越丰富,但显存和计算耗时也会增加。 * *Note: Changing resolution requires clicking "Generate Noise" again.* (注意:修改分辨率后需要再次点击 "Generate Noise" 才能生效。) ### 2. Base Shape - R Channel (基础形状 - R通道) Defines the main body and structure of the clouds. 定义云朵的主体结构。 * **Base Frequency Exp:** Controls the scale of the Perlin noise. Higher values = smaller, more frequent cloud clumps. * 控制 Perlin 噪声的频率(缩放)。数值越高,云朵的团块越小、越密集。 * **Base Octaves:** The number of noise layers. Higher values add more fine detail to the base shape. * 噪声的层级数(八度)。数值越高,基础形状的细节层次越丰富。 * **Base Persistence:** How much each octave contributes. Higher values make the surface "rougher". * 持续度。数值越高,高频细节的占比越大,云朵表面看起来越“粗糙”。 ### 3. Base Worley Settings (基础 Worley 设置) Modifies the Perlin noise to look more "puffy" (Cumulus-like). 用于修饰 Perlin 噪声,使其看起来更具“棉花糖”般的堆积感(积云特征)。 * **Worley Scale Exp:** The size of the Worley cells. * Worley 晶格的大小。 * **Base Coverage:** Controls the fill rate. Lower values make the clouds wispier; higher values make them thicker. * 覆盖率。数值越低,云越稀薄(絮状);数值越高,云越厚实。 ### 4. Detail - G Channel (细节 - G通道) High-frequency noise used for eroding the edges of the cloud to create realistic wisps. 用于侵蚀云朵边缘的高频噪声,制造出真实的丝状细节。 * **Detail Frequency/Octaves/Persistence:** Same logic as above, but applied to the detail layer (Green Channel). * 逻辑同上,但仅作用于细节层(绿色通道)。 ### 5. Rendering Settings - Preview Only (渲染设置 - 仅预览) These settings only affect how the noise looks in the Inspector preview, **not the exported file**. 这些设置**仅影响编辑器内的预览效果**,不会改变导出的文件。 * **Noise Scale:** Adjusts the tiling of the preview material. * 调整预览材质的平铺缩放,用于检查纹理细节。 * **Noise Offset:** Scrolls the noise to check continuity (seamless tiling). * 滚动噪声位置,用于检查纹理是否无缝衔接。 ### 6. Export Settings (导出设置) * **Compress DDS (BC6H/BC7):** * **Checked (勾选):** Uses `texconv` to compress the texture (Recommended for runtime). **BC6H** is used for HDR/High precision, **BC7** for standard usage. * 使用 `texconv` 进行压缩(推荐用于运行时)。**BC6H** 适用于 HDR 高精度需求,**BC7** 适用于标准需求。 * **Unchecked (未勾选):** Exports uncompressed RGBA32 volume texture (Large file size). * 导出未压缩的 RGBA32 体积纹理。 --- ## Dependencies / 依赖说明 This tool relies on **Microsoft DirectXTex** for DDS processing. 本工具依赖 **Microsoft DirectXTex** 进行 DDS 处理。 * You **do not** need to download them manually. * 你**无需**手动下载这些工具。 * The script will automatically detect missing tools and download `texconv.exe` and `texassemble.exe` to your project's `Library/ToolCache/` folder upon first use. * 脚本会在首次运行时自动检测,并自动将 `texconv.exe` 和 `texassemble.exe` 下载到你项目的 `Library/ToolCache/` 目录中。 --- ## License / 许可 This project is licensed under the **MIT License**. 本项目采用 **MIT 许可证**。 * **Third Party Notices (第三方声明):** * This tool automatically downloads binaries from [Microsoft DirectXTex](https://github.com/microsoft/DirectXTex), which is also licensed under the MIT License. * 本工具自动下载并使用的 **Microsoft DirectXTex** 二进制文件同样遵循 MIT 许可证。
