5.0 (#60)

* feat: Add Bioxel asset catalog and layer management functionality

- Introduced a new asset catalog definition file for Blender to manage Bioxel assets.
- Implemented layer caching and snapshot functionality in `layer.py`, allowing for VDB file generation and low-resolution snapshots.
- Created node management functions in `node.py` for handling Bioxel nodes within Blender's Geometry Node Editor.
- Added an operator to extract mesh data from selected nodes in `structure.py`.
- Developed UI panels in `panels.py` for layer management, including import options and layer library display.

* Add unit tests for bioxel module and documentation

- Created README.md for test instructions and categories.
- Implemented comprehensive unit tests for the Data, Layer, and utility functions in the bioxel module.
- Added tests for reading NRRD and DICOM formats, data properties, and edge cases.
- Included tests for real data files to ensure functionality with actual datasets.

* feat: Update .gitattributes and .gitignore for improved asset management and ignore patterns

chore: Add app.json and omoolab.css for Obsidian integration

refactor: Clean up AGENTS.md and remove outdated test files

* feat: Update .gitignore to include scipy_ndimage directory

* feat: Update release workflow and manifest for improved dependency management and layer handling

* feat: Update .gitignore and add binary files for scipy_ndimage across multiple platforms

* feat: Add OPSX commands for archiving, exploring, and proposing changes

* feat: Refactor asset library management and update manifest for improved organization

* feat: Downgrade h5py version to 3.14.0 in requirements and manifest

* feat: Update Help operator and panel labels to use English terminology

* Translate documentation to Chinese, add support format details, and enhance styling with new fonts. Update mkdocs configuration for multilingual support and improve package dependencies.

* feat: Remove default version setting from extra configuration in mkdocs.yml

* fix: Update documentation links to point to the correct URLs for Chinese and English versions

* Add documentation for basic usage, supported formats, and performance tips

- Created English and Chinese documentation for basic usage of the add-on, including data download, import, extraction, and rendering steps.
- Added support format documentation listing compatible file types for the add-on.
- Included links to open databases for volumetric data.
- Provided performance improvement tips for voxel reconstruction and rendering, including settings for low-resolution previews and balanced rendering configurations.

+## 切割「结构体」
+
+「结构体」可以被切割，呈现部分结构，通过 O Cut 系列节点完成。比如按下图添加 **O Cut to Region** 节点并连接，添加任意来自场景的物体作为「区域」，输入到节点：
+
+![](assets/cut-to-region.png)
+
+适当调整作为「区域」物体的位置旋转，可以看到头骨结构被限制在区域范围内。
+
+!!! note
+    插件提供快速让物体虚化的功能，在 3D 视图模式下，右键「区域」物体，菜单选择 **Bioxel Nodes > Toggle Phantom**
+
+!!! warning
+    切割会增加计算量，影响实时性能，勾选 O Layer 的 Resample 来提高性能
+
+
+
+**O Cut Small Parts** 节点，是清理神器，能快速把零碎的结构删除，只干净连续的大结构。但是计算特别耗时，注意性能。
+
+![](assets/cut-small-parts.png)
+
+如果你对几何节点很了解，你也可以通过 **O Cut Structure** 直接定义切割的执行范围，比如下图中，选择切割位置 X 大于 0 的部分。
+
+![](assets/cut-structure.png)
+
+
+## 「结构体」属性设置
+
+展开 **O Cutout by Threshold** 的 Properties，你可以直接修改各项属性值，但都只能均一设置，我们可以用场类型数据赋予差异。以颜色属性为例，比如直接接入 Position 节点，效果如下：
+
+![](assets/set-color-by-pos.png)
+
+我们还可以把数据层的值映射为颜色渐变，这里需要用到 **O Scalar Layer to Color** 节点（这类转换功能的节点都在节点菜单，Add > O Bioxel > Utilities 下）。调整如下
+
+- **O Cutout by Threshold**：Threshold 设置为 20
+- **O Scalar Layer to Color**：From Min 和 From Max 分别设置为 20 和 90
+
+![](assets/scalar-to-color.png)
+
+由于软组织的 CT 值小于骨质，当阈值降低，可以看到除了头骨外，附着的软组织也被呈现了出来。**O Scalar Layer to Color** 的 From Min 和 From Max，定义了颜色从 0~1 的取值范围。因此低值的软组织呈现黑色，高值的骨质呈现白色
+
+我们还可以通过 Blender 5.0+ 的 **Closure** 节点来自定义映射方式。比如连接 **Color Ramp** 节点，把属于软组织的黑区，改为暗红色
+
+![](assets/scalar-to-color-ramp.png)
+
+哒哒！解剖渲染就做好啦👍
+
+其他「结构体」属性也可以按这样的方式调整，除了 **O Scalar Layer to Color**，还有 **O Scalar Layer to Factor** 来转换为 0~1 的单值
