So how to color the RNPs alone?</p> <p>First of all, we have to separate the RNPs. The value of RNPs is between the membrane and S protein, so it is very difficult to separate. The good thing is that the virus is spherical, we can separate the RNPs part of the virus from the rest by using a sphere cutter. To do so, in the Geometry Nodes panel menu of the container, click Bioxel Nodes &gt; Add a Cutter &gt; Sphere Cutter, and adjust the scale and position of the newly created sphere object named \"Sphere_Cutter\" appropriately, so that it can just separate the internal RNPs and membrane of the virus.</p> <p></p> <p>The process of changing the position of the \"Sphere_Cutter\" object can be very laggy, then you can turn off \"With Surface\" and do it in Slice Viewer mode. Once you are happy with it, you can restore the settings.</p> <p>Then we turn on Invert in the \"Sphere Cutter\" node and you can see the opposite result. This way we've managed to separate the two, next let's color them separately and finally merge them with Join Component. Create and join the nodes as shown below, where the second Cutter node is copied and the color value in Set Color is <code>FFDDFE</code> (0.5). If all is well, the rendering should look like below.</p> <p></p> <p>At this point, the rendering of a SARS-Cov-2 virus is complete!</p>"},{"location":"en/SARS-Cov-2/#render-rnps-and-membranes","title":"Render RNPs and Membranes","text":"<p>Realistic rendering is great, but Non-photorealistic rendering (NPR) is better for presenting structural information. So I will render ultrastructure of the RNPs assembly with toon shader.</p> <p></p> <p>The silhouettes of RNPs uses Blender's Line Art feature, but Line Art must be based on a mesh. Select the nodes that are extruding the RNPs (i.e., the \"Cut\" nodes that are in charge of cutting out the RNPs), and right-click, click Bioxel Nodes &gt; Extract Mesh.

They can be controlled individually or combined with each other to build complex scenes. Next, let's try cutouting muscle from the VHP anatomical images and attaching the muscles to the skull that created in the previous section. The anatomical images are very large, so I've cropped and scaled them down to 1/4 of their original size for ease of use. Download the file and unzip it into a new directory.</p> <p>VHP_M_AnatomicalImages_Head.zip</p> <p>You can also download the data directly from the official website, https://data.lhncbc.nlm.nih.gov/public/Visible-Human/Male-Images/PNG_format/head/index.html</p> <p>First import the CT data as described in step by step. Then import the anatomical images, but unlike before, this time from the Geometry Nodes menu of the existing container (not the top menu), click Bioxel Nodes &gt; Import Volumetric Data (Init) &gt; as Color, locate to the unzipped folder, and select any .png file (do not multi-select, and do not select the folder). This way the imported layer will be in the same container as the previous CT data. You can also import by dragging it into the container geometry node interface instead of the 3D Viewport interface. Also note that as Color (not as Scalar) is clicked because the anatomical images are RGB data.</p> <p></p> <p>Let's take more time in the import options this time \ud83e\udee1, first let's talk about what the Original Spacing is in the options, you can simply think of it as the original \"pixel size\" of a image, since the volume is 3D, its pixels (i.e., voxels) are cuboids with a length, width, and height rather than 2D rectangles. And their length, width, and height size is the Spacing.</p> <p>Normally, Bioxel Nodes can read the spacing from the data header, and you don't need to fill in the value, but there is no record of that in any PNG image, so you need to input it manually. in the official description of the VHP, it is mentioned that each pixel of the anatomical images corresponds to the size of .33mm, and the thickness of each slice is 1mm, so the Original Spacing of the anatomical images should be set to <code>(0.33, 0.33, 1)</code>.</p> <p>However, the file I provided is scaled by 1/4 for each image, so the X and Y axes need to be multiplied by 4. So the final Original Spacing should be set to <code>(1.33, 1.33, 1)</code>, which should be understandable, right? (If you are importing an official file, then it should still be set to <code>(0.33, 0.33, 1)</code>) Layer Name should be set to \"Anatomical Images\", other options remain default, click Ok.</p> <p></p> <p>After importing, connect the \"Cutout by Hue\" node (Add &gt; Bioxel Nodes &gt; Component &gt; Cutout by Hue) after the newly created \"Fetch Layer\" node, and turn on the Slice Viewer mode preview, as shown below.</p> <p></p> <p>In addition to spacing, the Dicom file also records the subject's position and orientation, but those information is apparently not recorded in PNG format. This results in a mismatch between the CT data and the anatomical images in position. We need to manually align this two layers: First, set the threshold of the \"Cutout by Threshold\" node to 0.2 so that the full head can be cutouted and displayed. Then add \"ReCenter\" node before \"Cutout by Hue\" node and \"Cutout by Threshold\" node each, then add Locater to the \"anatomical images\" workflow (see step by step for details), and finally add \"Join Component\" node (Add &gt; Bioxel Nodes &gt; Component &gt; Join Component), and connect them as shown below, with the parameters set as shown.</p> <p></p> <p>The \"Join Component\" node allows you to merge two components together. Move and rotate the Locater object so that the two components are exactly the same in position. If you're having trouble matching them up, here's the exact transform values to fill in the Locater object properties.</p> <p></p> <p>Next let's cutout the muscles individually.</p> <p>First let's talk about the \"Cutout by Hue\" node. Literally, it cutout regions by hue of color. If you select this node and press \"M\" key to temporarily mute it, you'll see that the data becomes a cube with blue parts in Slice Viewer mode. the default value of Hue in the \"Cutout by Hue\" node is red, meaning that the node retains areas of the body that are close to red, and strip out the blue, which is on the opposite side of the red in the hue ring, leaving the human body parts.</p> <p>If you turn down the value of Sensitivity, you'll see that the visabile part is decreasing, leaving only the part more closer to red, and the muscle happens to be red, so we can easily cutout the muscle. The color of the specimen tissue is not as vibrant as it is in the live state, and we can fine-tune the color to restore the vibrancy by using the \"Set Color by Color\" node (Add &gt; Bioxel Nodes &gt; Property &gt; Set Color by Color).</p> <p>To finally put it all together, connect and set the nodes as shown below, where the two colors in \"Set Color by Ramp 2\" node are <code>E7D2C5</code> and <code>FFEDEC</code>. If everything is working correctly, you'll get the rendering below.</p> <p></p> <p>You can also add \"Transfrom\" and \"Cutter\" nodes at the end and all components.</p> <p></p> <p>The multimodal data of VHP do not have any deformation or scaling differences, but only positional differences, so all data can be aligned easily. However, in most cases, the differences of different modalities are so great that they need to be registered first, which is not possible with Bioxel Nodes at the moment (but it is in plan). Nevertheless, you can build different components based on the same layer and combine them together. For example, based on the CT data, with the \"Cutout by Range\" node, you can eliminate the low value regions (fat), eliminate the high value regions (bone), and you can still get the muscle. And then attach it to the skull.</p> <p></p> <p>However, the CT values of brain and muscle are very close to each other, so it is extremely difficult to separate the brain from the muscle by threshold. So how should cutout the brain?</p>"},{"location":"en/advanced_usage/#cutout-the-brain","title":"Cutout the Brain","text":"<p>We can use AI technology to realize the division of brain regions, this process is called Segmentation, and the brain regions are as label.

Once the import is complete, a new \"Fetch Layer\" node will be added. Create and set the node as shown below, and you should be able to see the surface of brain.</p> <p></p> <p>Do you see the \"step\" like shape on surface? this is due to the low precision of the AI segmentation results. So How to addressing the issue? Select the Fetch Layer node of the brain label, right-click to pop up menu, click Bioxel Nodes &gt; Resample Value, in the dialog box, change the \"Smooth Size\" to 3 or higher (the higher it is, the slower the calculation will be), click OK and wait for the calculation to finish. When it is done, a new layer will be added, replace the original one, is it smoother? The following figure lists different levels of smoothing.</p> <p></p> <p>The smoother it is, the more comfortable it looks, but it also means that more details are lost and the calculation is slower.</p> <p>But if you cut the brain, you will find that the cross-section is homogeneous, this is because the label type layer is does not contain any modality data itself. Bioxel Nodes provides a function to fill in any layer values by label, if you set the value below brain tissue in the non-brain region of CT data, then any \"Cutout\" node will only keep the brain region.</p> <p>The operation is like this, select the \"Fetch Layer\" node of the CT data, right-click to pop up the menu, click Bioxel Nodes &gt; Fill Value by Label, in the dialog box, Label is set to the newly imported brain label layer, Fill Value is set to -100 (as long as it is less than the Hu value of the brain tissue), click OK. wait for the data processing, a new data layer will be added to the container when it is finished.</p> <p>As shown in the following figure, connect the nodes and set the node parameters, in which the two colors of \"Set Color by Ramp 2\" node are <code>B26267</code> and <code>EBC5B7</code>, and the \"Cutout by Range\" and \"Set Color by Ramp 2\" node are changed to \"Value\" mode (the default is \"Factor\" mode), because the maximum and minimum values of the brain are too close to each other and difficult to adjust in \"Factor\" mode. To make the brain tissue look more transparent, I add the \"Set Properties\" (Add &gt; Bioxel Nodes &gt; Property &gt; Set Properties) node at the end and changed the \"Density\" to 0.5.</p> <p></p> <p>(Still feel not smooth enough? It's really hard to get rid of \"step\" surface completely at the moment)</p> <p>Now the brain is done.

So how to color the RNPs alone?</p> <p>First of all, we have to separate the RNPs. The value of RNPs is between the membrane and S protein, so it is very difficult to separate. The good thing is that the virus is spherical, we can separate the RNPs part of the virus from the rest by using a sphere cutter. To do so, in the Geometry Nodes panel menu of the container, click Bioxel Nodes &gt; Add a Cutter &gt; Sphere Cutter, and adjust the scale and position of the newly created sphere object named \"Sphere_Cutter\" appropriately, so that it can just separate the internal RNPs and membrane of the virus.</p> <p></p> <p>The process of changing the position of the \"Sphere_Cutter\" object can be very laggy, then you can turn off \"With Surface\" and do it in Slice Viewer mode. Once you are happy with it, you can restore the settings.</p> <p>Then we turn on Invert in the \"Sphere Cutter\" node and you can see the opposite result. This way we've managed to separate the two, next let's color them separately and finally merge them with Join Component. Create and join the nodes as shown below, where the second Cutter node is copied and the color value in Set Color is <code>FFDDFE</code> (0.5).

They can be controlled individually or combined with each other to build complex scenes. Next, let's try cutouting muscle from the VHP anatomical images and attaching the muscles to the skull that created in the previous section. The anatomical images are very large, so I've cropped and scaled them down to 1/4 of their original size for ease of use. Download the file and unzip it into a new directory.</p> <p>VHP_M_AnatomicalImages_Head.zip</p> <p>You can also download the data directly from the official website, https://data.lhncbc.nlm.nih.gov/public/Visible-Human/Male-Images/PNG_format/head/index.html</p> <p>First import the CT data as described in step by step. Then import the anatomical images, but unlike before, this time from the Geometry Nodes menu of the existing container (not the top menu), click Bioxel Nodes &gt; Import Volumetric Data (Init) &gt; as Color, locate to the unzipped folder, and select any .png file (do not multi-select, and do not select the folder). This way the imported layer will be in the same container as the previous CT data. You can also import by dragging it into the container geometry node interface instead of the 3D Viewport interface. Also note that as Color (not as Scalar) is clicked because the anatomical images are RGB data.</p> <p></p> <p>Let's take more time in the import options this time \ud83e\udee1, first let's talk about what the Original Spacing is in the options, you can simply think of it as the original \"pixel size\" of a image, since the volume is 3D, its pixels (i.e., voxels) are cuboids with a length, width, and height rather than 2D rectangles. And their length, width, and height size is the Spacing.</p> <p>Normally, Bioxel Nodes can read the spacing from the data header, and you don't need to fill in the value, but there is no record of that in any PNG image, so you need to input it manually. in the official description of the VHP, it is mentioned that each pixel of the anatomical images corresponds to the size of .33mm, and the thickness of each slice is 1mm, so the Original Spacing of the anatomical images should be set to <code>(0.33, 0.33, 1)</code>.</p> <p>However, the file I provided is scaled by 1/4 for each image, so the X and Y axes need to be multiplied by 4. So the final Original Spacing should be set to <code>(1.33, 1.33, 1)</code>, which should be understandable, right? (If you are importing an official file, then it should still be set to <code>(0.33, 0.33, 1)</code>) Layer Name should be set to \"Anatomical Images\", other options remain default, click Ok.</p> <p></p> <p>After importing, connect the \"Cutout by Hue\" node (Add &gt; Bioxel Nodes &gt; Component &gt; Cutout by Hue) after the newly created \"Fetch Layer\" node, and turn on the Slice Viewer mode preview, as shown below.</p> <p></p> <p>In addition to spacing, the Dicom file also records the subject's position and orientation, but those information is apparently not recorded in PNG format. This results in a mismatch between the CT data and the anatomical images in position. We need to manually align this two layers: First, set the threshold of the \"Cutout by Threshold\" node to 0.2 so that the full head can be cutouted and displayed. Then add \"ReCenter\" node before \"Cutout by Hue\" node and \"Cutout by Threshold\" node each, then add Locater to the \"anatomical images\" workflow (see step by step for details), and finally add \"Join Component\" node (Add &gt; Bioxel Nodes &gt; Component &gt; Join Component), and connect them as shown below, with the parameters set as shown.</p> <p></p> <p>The \"Join Component\" node allows you to merge two components together. Move and rotate the Locater object so that the two components are exactly the same in position. If you're having trouble matching them up, here's the exact transform values to fill in the Locater object properties.</p> <p></p> <p>Next let's cutout the muscles individually.</p> <p>First let's talk about the \"Cutout by Hue\" node. Literally, it cutout regions by hue of color. If you select this node and press \"M\" key to temporarily mute it, you'll see that the data becomes a cube with blue parts in Slice Viewer mode. the default value of Hue in the \"Cutout by Hue\" node is red, meaning that the node retains areas of the body that are close to red, and strip out the blue, which is on the opposite side of the red in the hue ring, leaving the human body parts.</p> <p>If you turn down the value of Sensitivity, you'll see that the visabile part is decreasing, leaving only the part more closer to red, and the muscle happens to be red, so we can easily cutout the muscle. The color of the specimen tissue is not as vibrant as it is in the live state, and we can fine-tune the color to restore the vibrancy by using the \"Set Color by Color\" node (Add &gt; Bioxel Nodes &gt; Property &gt; Set Color by Color).</p> <p>To finally put it all together, connect and set the nodes as shown below, where the two colors in \"Set Color by Ramp 2\" node are <code>E7D2C5</code> and <code>FFEDEC</code>. If everything is working correctly, you'll get the rendering below.</p> <p></p> <p>You can also add \"Transfrom\" and \"Cutter\" nodes at the end and all components.</p> <p></p> <p>The multimodal data of VHP do not have any deformation or scaling differences, but only positional differences, so all data can be aligned easily. However, in most cases, the differences of different modalities are so great that they need to be registered first, which is not possible with Bioxel Nodes at the moment (but it is in plan). Nevertheless, you can build different components based on the same layer and combine them together. For example, based on the CT data, with the \"Cutout by Range\" node, you can eliminate the low value regions (fat), eliminate the high value regions (bone), and you can still get the muscle. And then attach it to the skull.</p> <p></p> <p>However, the CT values of brain and muscle are very close to each other, so it is extremely difficult to separate the brain from the muscle by threshold. So how should cutout the brain?</p>"},{"location":"en/advanced_usage/#cutout-the-brain","title":"Cutout the Brain","text":"<p>We can use AI technology to realize the division of brain regions, this process is called Segmentation, and the brain regions are as label.

The following figure lists different levels of smoothing.</p> <p></p> <p>The smoother it is, the more comfortable it looks, but it also means that more details are lost and the calculation is slower.</p> <p>But if you cut the brain, you will find that the cross-section is homogeneous, this is because the label type layer is does not contain any modality data itself. Bioxel Nodes provides a function to fill in any layer values by label, if you set the value below brain tissue in the non-brain region of CT data, then any \"Cutout\" node will only keep the brain region.</p> <p>The operation is like this, select the \"Fetch Layer\" node of the CT data, right-click to pop up the menu, click Bioxel Nodes &gt; Fill Value by Label, in the dialog box, Label is set to the newly imported brain label layer, Fill Value is set to -100 (as long as it is less than the Hu value of the brain tissue), click OK. wait for the data processing, a new data layer will be added to the container when it is finished.</p> <p>As shown in the following figure, connect the nodes and set the node parameters, in which the two colors of \"Set Color by Ramp 2\" node are <code>B26267</code> and <code>EBC5B7</code>, and the \"Cutout by Range\" and \"Set Color by Ramp 2\" node are changed to \"Value\" mode (the default is \"Factor\" mode), because the maximum and minimum values of the brain are too close to each other and difficult to adjust in \"Factor\" mode. To make the brain tissue look more transparent, I add the \"Set Properties\" (Add &gt; Bioxel Nodes &gt; Property &gt; Set Properties) node at the end and changed the \"Density\" to 0.5.</p> <p></p> <p>(Still feel not smooth enough? It's really hard to get rid of \"step\" surface completely at the moment)</p> <p>Now the brain is done. Finally we combine all together and you get something like the following.</p> <p></p> <p>\ud83e\udd17 If you've followed the docs up to this point, give yourself a round of applause, you've mastered this addon!
