-Bioxel Nodes is a Blender extension for scientific volumetric data visualization. It using Blender's powerful Geometry Nodes and Cycles to process and render volumetric data. You are free to share your blender file to anyone who does not install this extension, since most processes were done by Blender's native nodes.
-
-## About
-
-Before us, there have been many tutorials and extensions for importing volumetric data into Blender. However, we found that there were many scientific issues that were not addressed in place, and the volume render results were not epic. With Bioxel Nodes, you can easily import any format volumetric data into Blender, and more importantly, make a beautiful realistic volume rendering quickly.
-
-Below are some examples with Bioxel Nodes. Thanks to Cycles Render, the volumetric data can be rendered with great detail:
+Bioxel Nodes is a Blender addon for scientific volumetric data visualization. It using Blender's powerful **Geometry Nodes** and **Cycles** to process and render volumetric data.

-So how to use this extension? please check [Getting Started](https://omoolab.github.io/BioxelNodes/latest/getting-started)
+-   Fantastic rendering result, also support EEVEE NEXT
+-   Support multiple formats
+-   Support 4D volumetric data
+-   All kinds of cutters
+-   Simple and powerful nodes
+-   Based on blender natively, can work without addon.

+## Support 4D volumetric data
+
+![4d](https://omoolab.github.io/BioxelNodes/latest/assets/4d-time.gif)
+
+🥰 4D volumetric data can also be imported into Blender.
+
+## Support EEVEE NEXT
+
+![eevee](https://omoolab.github.io/BioxelNodes/latest/assets/eevee.gif)
+
+👍 EEVEE NEXT is absolutely AWESOME! Bioxel Nodes is fully support EEVEE NEXT now! However, there are some limitations:
+
+1. Only one cutter supported.
+2. EEVEE result is not that great as Cycles does.
 
 ## Known Limitations
 
--   Sections cannot be generated (will be supported soon)
--   Time sequence volume not supported (will be supported soon)
+-   Only works with Cycles CPU , Cycles GPU (OptiX), EEVEE
+-   Section surface cannot be generated when convert to mesh (will be supported soon)
 
-## Upgrade from 0.1.x to 0.2.x
+## Compatibile to Newer Version
 
-You need to do the following:
+**Updating this addon may break old files, so read the following carefully before updating**
 
-1. Remove the old version of Bioxel Nodes at Preferences > Add-ons
-2. Add the new version and restart Blender.
+Before updating this addon, you need to ask yourself whether this project file will be modified again or not, if it's an archived project file, I would recommend that you run **Bioxel Nodes > Save Staged Data** to make the addon nodes permanent. In this way, there will be no potential problem with the nodes not functioning due to the addon update.
 
-It is not support editing the same blender file across extension versions. In order to make sure that the previous file works properly. You need to save the staged data before upgrading ( read the last section of [Getting Started](https://omoolab.github.io/BioxelNodes/latest/getting-started/#share-your-file) ).
+After the addon update, your old project files may not work either, this may be because you had executed **Save Staged Data**. If so, you need to execute **Bioxel Nodes > Relink Nodes to Addon** to relink them to make sure that the addon's new functionality and the addon nodes are synchronized.
 
-But even then, there is still no guarantee that the new version of the extension will work on the old blender file. Therefore, it is highly recommended to open a new blender file to start the creating, not based on the old one.
+Also, unlike the newer versions, the older shaders are not based on OSL, so if you find that you can't render volumes, you need to turn on **Open Shading Language (OSL)** in the Render Settings.
 
-Alternatively, objects from the old file that have nothing to do with Bioxel Nodes could be append to the new blender file.
+## Roadmap
 
-## About EEVEE Render
-
-Bioxel Nodes is designed for Cycles Render. However, it does support eevee render partially. "Solid Shader" node and "Volume Shader" node have a toggle called "EEVEE Render". If you want to render Bioxel Component in real-time, turn it on.
-
-Also, there are some limitations:
-
-1. Only one cutter supported.
-2. You cannot use "Color Ramp" over 2 colors.
-3. EEVEE Render result is not that great as Cycles does.
-
-> "Volume Shader" node is not work properly in EEVEE Next since 4.2. It is because EEVEE Next is not support attributes from instances of volume shader by now. But the Blender 4.2 docs still say attributes reading is ok, so I suppose this feature will eventually be implemented.
+-   Better multi-format import experience
+-   One-click bake model with texture
+-   AI Segmentation to Generate Labels

+## Container, Layer, Component
+
+Bioxel Nodes imports volumetric data and put it into a **Container** as a **Layer**. One container may has more than one layer, and each layer stores the information of different fields under the same location, which is similar to the view layers in map app, except that here it is in 3D space.
+
+In order to visualize the volumetric data the way we want it to, we need to build renderable objects from layers. We call those objects **Component**. The following diagram shows the relationship of **Container**, **Layer**, and **Component**:
+
+![alt text](assets/features_concept.png)
+
+### Container Structure
+
+In Blender, container structure is like this:
+
+```bash
+Case_0000 # Container
+|-- Case_0000_CT # Layer
+|-- Case_0000_Label_1 # Layer
+`-- Case_0000_Label_2 # Layer
+```
+
+The container also stores the build process in geometry nodes:
+
+![alt text](assets/features_container.png)
+
+### Layer Type
+The layer is categorized into these by data type:
+
+-   Scalar
+-   Label
+-   Vector (Not implemented yet)
+-   Color (Not implemented yet)
+
+## Component Building Pipline
+
+In order to build a component, the general process is to first use a "Mask Method" node to build the surface of the component based on its layers, and then connect to a "Assign Shader" node to add the physical properties. Finally, if you need to cut the cross-section, then connect to a "Cut" node. The whole process is shown in the following diagram
+
+![alt text](assets/nodes_concept.png)
+
+A typical example looks like this:
+
+![alt text](assets/nodes_example.png)
+
+The "Mask Method" node tends to be very computationally intensive, and if it consumes too much time, then you can bake it with a "Bake" node after it (but you need to save the Blender file first).

-# Getting Started
-
-Currently only support Blender 4.0 or above, make sure you have the correct version of Blender.
-
-## Add-on Installation
-
-#### For Blender 4.2 or higher
-
-Download the **Extension** version `BioxelNodes_Extension_{version}.zip` from https://github.com/OmooLab/BioxelNodes/releases/latest  
-In Blender, Edit > Preferences > Extensions > Install from Disk, select the zip file you just downloaded.
-
-Thats it!
-
-> If it cannot be enable, just reboot blender.
-
-#### For Blender 4.0 or 4.1
-
-Download the **Addon** version `BioxelNodes_Addon_{version}.zip` from https://github.com/OmooLab/BioxelNodes/releases/latest  
-In Blender, Edit > Preferences > Add-ons > Install, select the zip file you just downloaded.
-
-The add-on requires a third-party python dependency called SimpleITK, click `Install SimpleITK` button below to install the dependency. After clicking, blender may get stuck, it is downloading and installing, just wait for a moment. After that, click `Reboot Blender` button.
-
-![dependency](assets/getting-started_dependency.png)
-
-This step may have failed due to network factors, just click "Set PyPI Mirror" to change the mirror.
-
-## Prepare Your Data
-
-First you need to have your volumetric data ready. If not, you can access open research data from list below.
-
-> Note that just because they are open and available for download does not mean you can use them for anything! Be sure to look at the description of the available scopes from website.

-## Import Volume Data
-
-File > Import > Volume Data as Bioxel Layer, select **one** of the .dcm files and click on "Volume Data as Bioxel Layer" (you can also drag one of the .dcm files directly into the 3D viewport to trigger the import)
-
-![importing](assets/getting-started_importing.png)
-
-It may take a while to read data. After finishing reading, it will pop up a dialog box. Ignore all the options, just click OK (we will tell about these options later).
-
-After importing the data, the add-on will automatically add the necessary nodes to build the component. Click on the new created object in outliner, open the geometry nodes panel, set `Threshold` in "Mask by Threshold" node to 200, and then connect a Slime Shader node (Add > Bioxel Nodes > Slime Shader) after it. The node graph should be as following:
-
-![alt text](assets/getting-started_graph.png)
-
-and then turned on the cycles rendering to directly see the result.
-
-![result](assets/getting-started_result.png)
-
-You can change the "Threshold" to modify the preview model, or change the "Color", "Density" to modify the shader effect. All the parameters are straightforward, you can understand them by changing the values.
-
-## Share Your File
-
-The VDB cache and the Bioxel nodes are not reachable to other computers if you don't save them. If you want to give your blender file to someone else, you will need to perform the following steps first:
-
-1. Save your blender file
-2. Click Scene > Bioxels > Save All Bioxels in the properties panel.
-3. Click Scene > Custom Nodes > Save All Custom Nodes in the properties panel.
-
-![alt text](assets/getting-started_share-file.png)
-
-After that, both the VDB cache and the Bioxel nodes are restored in relative locations. When you share this file with someone, pack the entire directory so that the resources will be not lost. The other person will be able to open it correctly, regardless of whether they have Bioxel Nodes installed or not.

-Bioxel Nodes is a Blender add-on for scientific volumetric data visualization. It using Blender's powerful Geometry Nodes | Cycles to process and render volumetric data.
-
-## About
-
-Before us, there have been many tutorials and add-ons for importing volumetric data into Blender. However, we found that there were many details that were not addressed in place, some scientific facts were ignored, and the volume rendering was not pretty enough. With Bioxel Nodes, you can easily import the volumetric data into Blender, and more importantly, it can quickly make a beautiful realistic rendering of it.
-
-Below are some examples with Bioxel Nodes. Thanks to Cycles Render, the volumetric data can be rendered with great detail:
+Bioxel Nodes is a Blender addon for scientific volumetric data visualization. It using Blender's powerful **Geometry Nodes** and **Cycles** to process and render volumetric data.

-The "Bioxel" in "Bioxel Nodes", is a combination of the words "Bio-" and "Voxel". Bioxel is a voxel that stores biological data. We are developing a toolkit around Bioxel for better biological data visualization. but before its release, we made this Blender version of bioxels toolkit first, in order to let more people to have fun with volumetric data. [Getting Started](https://omoolab.github.io/BioxelNodes/latest/getting-started)
+-   Fantastic rendering result, also support EEVEE NEXT

-## To Upgrade Add-on
+## Compatibile to Newer Version
 
-To upgrade from an older version of the add-on to the latest, you need to do the following:
+**Updating this addon may break old files, so read the following carefully before updating**
 
-1. Remove the old version of Bioxel Nodes at Preferences > Add-ons
-2. Add the new version and restart Blender.
+Before updating this addon, you need to ask yourself whether this project file will be modified again or not, if it's an archived project file, I would recommend that you run **Bioxel Nodes > Save Staged Data** to make the addon nodes permanent. In this way, there will be no potential problem with the nodes not functioning due to the addon update.
 
-It is not support editing the same blender file across add-on versions. In order to make sure that the previous file works properly. You need to save the staged data before upgrading ( read the last section of [Getting Started](https://omoolab.github.io/BioxelNodes/latest/getting-started/#share-your-file) ).
+After the addon update, your old project files may not work either, this may be because you had executed **Save Staged Data**. If so, you need to execute **Bioxel Nodes > Relink Nodes to Addon** to relink them to make sure that the addon's new functionality and the addon nodes are synchronized.
 
-But even then, there is still no guarantee that the new version of the add-on will work on the old blender file. Therefore, it is highly recommended to open a new blender file to start the creating, not based on the old one.
+Also, unlike the newer versions, the older shaders are not based on OSL, so if you find that you can't render volumes, you need to turn on **Open Shading Language (OSL)** in the Render Settings.
 
-Alternatively, objects from the old file that have nothing to do with Bioxel Nodes could be append to the new blender file.
-
-## About EEVEE Render
-
-Bioxel Nodes is designed for Cycles Render. However, it does support eevee render partially. "Solid Shader" node and "Volume Shader" node have a toggle called "EEVEE Render". If you want to render Bioxel Component in real-time, turn it on.
-
-Also, there are some limitations:
-
-1. Only one cutter supported.
-2. You cannot use "Color Ramp" over 2 colors.
-3. EEVEE Render result is not that great as Cycles does.
-
-> "Volume Shader" node is not work properly in EEVEE Next since 4.2. It is because EEVEE Next is not support attributes from instances of volume shader by now. But the Blender 4.2 docs still say attributes reading is ok, so I suppose this feature will eventually be implemented.
+## Roadmap
+- Better multi-format import experience
+- One-click bake model with texture
+- AI Segmentation to Generate Labels

-- Generate sections
-- More segmentation methods, e.g. AI segmentation.

-
-### Bioxels
-
-Bioxels is based on the RAS coordinate system, Right Aanterior Superior, which was chosen over LPS because it is more compatible with most 3D CG software coordinate systems, and is in line with the 3D artist's understanding of space.
-
-All distances within Bioxels are in Units, and are specified in Meter pre unit. However, when Bioxels is imported into 3D CG software, its size in the software is not scaled by reading the Meter pre unit directly. The reason for this is that many 3D operations in software require that the primtives not be too large or too small.
-
-### Based on OpenVDB
-
-Bioxels is based entirely on OpenVDB for storage and rendering. The main reason for choosing OpenVDB is that as a volumetric data format, it is the fastest way to work with most CG renderers.
-
-### Based on Geometry Nodes
-
-Bioxel Nodes relies on Blender Geometry Nodes to reconstruct and render volumetric data. Node-based operations ensure that the original data is not permanently altered during reconstruction and rendering operations. The fact that the processing is based on Geometry Nodes without any additional dependencies also ensures that Blender can open files without this plugin installed. Look for more support for OpenVDB in GeometryNodes so that Bioxel Nodes can do more in the future.

 # Nodes
 
-## Nodes Design Concept
-
-In order to build a component, the general process is to first use a "Mask Method" node to build the surface of the component based on its layers, and then connect to a "Assign Shader" node to add the material physical properties. Finally, if you need to cut the cross-section, then connect to a "Cut" node. The whole process is shown in the following diagram
-
-![alt text](assets/nodes_concept.png)
-
-A typical example looks like this:
-
-![alt text](assets/nodes_example.png)
-
-The "Mask Method" node tends to be very computationally intensive, and if it consumes too much time, then you can bake it with a "Bake" node after it (but you need to save the Blender file first).

+# Step by Step
+
+## 1. Import Volumetric Data
+
+**Bioxel Nodes > Import Volumetric Data (Init) > as Scalar**, select the data file, click on **Import as Scalar**. If the data is a sequence of files in directory, just pick **one** file in that directory, not the whole directory or multiple selection of files.
+
+> you can also drag one of the data file directly into the 3D viewport to trigger the importing
+
+![importing](assets/getting-started_importing.png)
+
+It may take a while to read data. After finishing reading, it will pop up a dialog box. Ignore all the options, just click OK (we will talk about them later).
+
+After the importing, the add-on will automatically add the necessary nodes to build the preview.
+
+![masking](assets/getting-started_masking.png)
+
+If there is nothing in the bbox wireframe, select the wireframe in 3D viewport, open the geometry nodes panel, set **Threshold** in the node lower to modify the preview.
+
+## 2. Shading the Structure
+
+The only node "Scalar" is responsible for mask out the unwanted area and generate the structure surface. You need to assign a shader to truly see the structure, connect a **Slime Shader** node (**Add > Bioxel Nodes > Shaders > Slime Shader**) after it. Turned on the cycles rendering to see the result.
+
+![shading](assets/getting-started_shading.png)
+
+You may change the **Color**, **Density** to modify the shader effect. All the parameters are straightforward, you can understand them by changing their values.
+
+## 3. Cut to Cross-section
+
+We often need to cut the structure to see the inside of the volumetric data. With Bioxel Nodes, it can be done by one click: select the structure in 3D viewport, right click, **Bioxel Nodes > Add a Plane Cutter**
+. The add-on will add a cut node and a cutter object node to the node graph, which are responsible for the cutting process.
+
+![cutting](assets/getting-started_cutting.png)
+
+> Change the shader from **Slime** to **Universal** to render the cross-section. But it will increase rendering time
+
+## 4. Save Staged Data (Optional)
+
+The VDB cache and the custom nodes are not reachable to other computers if you don't save them. Those staged data should be saved, If you want to give your blender file to someone else, or you want to archive your blender file.
+
+Save your blender file, then just click **Bioxel Nodes > Save Staged Data**
+
+![save staged data](assets/getting-started_save_staged_data.png)
+
+Just click **OK**, after that, both the VDB cache and the custom nodes are restored in relative locations. When you share this file with someone, pack the entire directory so that the resources will be not lost. The other person will be able to open it correctly, regardless of whether they have Bioxel Nodes installed or not.
+
+## 5. Convert to Editable Mesh (Optional)
+
+If you want digital sculpting, 3D printing, exporting to game engine, you should convert to editable mesh first.
+
+Select the wireframe in 3D viewport, right click **Bioxel Nodes > Pick Mesh**.
