Here some of my first test of Dendro plugin. [image] Dendro Dendro is a volumetric modeling plug-in for Grasshopper built on top of the OpenVDB library. To my point of view this plugin brings the power of OpenVdB in Rhino/Grasshopper. It will certainly be ver…

[image] ryein: I’d be curious to get everyone’s thoughts on use cases because there are other ways to generate volume data other than by points or meshes. One potential use case for meshes is to clean up the inside of medical scan meshes (bones in this case). Bone meshes often end up littere…

@ryein Its a great plugin. Thank you for sharing. I will also play around with it this weekend. Using a proven library like openVDB will definitly find many useful applications. I‘ve also read your source code on github. Its a great example for a well written hybrid C# and C++ grasshopper plugin. …

[image] TomTom: Thats simply the difference between fully automated mesh modelling and high end surface modelling. Its impossible to have both. You want to fully automate a modelling process of f.e. medical parts, then you dont need to care much about surface quality. Its of much lower priority.…

Other Dendro uses here [image] (Exoskeleton) Mesh generation fails at Nodes Grasshopper Thanks for posting what you are doing. Yes it will be interesting to see the results. Some year ago I also made a node generator in Nurbs. It worked not perfactly, there is still a comp…

These display artifacts are likely caused by how the vertex normals are being calculated i.e. calling ComputeNormals on the display mesh. Taking vertex normals from the gradient of the scalar field should give a smoother (looking) result without much additional effort. See below for a comparison. […

The second option looks great :grinning:

Also, for cases where you don’t have access to a scalar field to get the gradient of, I made a little tool to apply some simple smoothing to the mesh normals by averaging neighbouring normals (not modifying vertex positions at all). [normalsmooth] smoothnormals.gh (36.8 KB)

@ryein , this is an amazing plugin and you are raising the bar really high by enabling a multi-threaded volumetric modeling tool that runs flawlessly in GH/Rhino. I did quick tests on some really intricate and high-resolution solid models and I should say I am in awe with the performance of the tool.…

@species Thanks for the response and I am glad you are digging the plugin. I am constantly blown away by what it can do and was really excited to throw it out to everyone. I think you could incorporate mathematical surfaces into the pipeline, but the output might not be what you’d want. Unless you…

Some more test using the smooth function of Dendro/OpenVdB, I was also inspired by Entagma [image] Isocontours: Importing & Exporting Vectors to/from Houdini – Entagma [dendro_smooth] [dendro_smooth_2]

How is this type of volumetric text modeled?
