Generating high fidelity surface meshes of neocortical neurons using skin modifiers
<h2>Summary</h2> <p>The dataset contained in this repository is the resulting meshes from applying the Skin Modifier in Blender on all neuronal morphological types (mtypes) identified for comastosensory cortical cells by the Blue Brain Project. </p> <p>The papser, <strong>Generating high fidelity surface meshes of neocortical neurons using skin modifiers,</strong> is published in the 2019 <em>EG Computer Graphics & Visual Computing (CGVC) </em>conference<em>. </em></p> <div><a href="https://doi.org/10.2312/cgvc.20191257">https://doi.org/10.2312/cgvc.20191257</a><br><a href="https://diglib.eg.org/handle/10.2312/cgvc20191257">https://diglib.eg.org:443/handle/10.2312/cgvc20191257</a></div> <h2>Paper abstract </h2> <div>We present the results of exploring the capabilities of skinning modifiers to generate high fidelity polygonal surface meshes of neurons from their morphological skeletons that are segmented from optical microscopy slides. Our algorithm is implemented in Blender as an add-on relying on its standard Python API. The implementation is also integrated into an open source domain specific framework, NeuroMorphoVis, that is used to visualize and analyze neuronal morphologies available from the neuroscientific community. Our technique is applied to create meshes for a set of neurons with 55 different morphologies reconstructed from the neocortex of a 14-days-old rat. The generated meshes are used to visualize full compartmental simulations of neocortical activity for analysis purposes and also to create high quality scientific illustrations of in silico neuronal circuits for media production with physically-based path tracers.</div> <h2>BibTex citation</h2> <blockquote> <p><em>@inproceedings {10.2312:cgvc.20191257,</em><br><em> booktitle = {Computer Graphics and Visual Computing (CGVC)},</em><br><em> editor = {Vidal, Franck P. and Tam, Gary K.

Mesh and velocity fields for "Resolving Pore-scale Concentration Gradients for Transverse Mixing and Reaction in Porous Media"
<p>This dataset contains the data needed to reproduce the results in the manuscript "Resolving Pore-scale Concentration Gradients for Transverse Mixing and Reaction in Porous Media". The three folders refer to (1) uniform flow, (2) flow through a bead pack, and (3) flow through a Berea sample (from the 11 sandstones repository, Digital Rocks Portal). The meshes and the velocity fields (in the subfolder "velocity") are in a HDF5 format. The meshes and velocity fields can be read using FEniCS version 2019.2.0. The velocity fields need 2nd order Lagrange tetrahedral elements.</p>
Global climatology of sea-surface methanethiol (MeSH) concentration fields
<p>This dataset contains a global climatology of sea-surface MeSH concentration and sea-to-air flux, as described in this article (see README file):</p> <p>Wohl, C., Villamayor, J., Galí, M., Mahajan, A. S., Fernández, R. P., Cuevas, C. A., Bossolasco, A., Li, Q., Kettle, A. J., Williams, T., Sarda-Esteve, R., Gros, V., Simó, R., and Alfonso Saiz-Lopez, A. (2024). Marine emissions of methanethiol increase aerosol cooling in the Southern Ocean. Science Advances, 10(48), eadq2465. DOI: 10.1126/sciadv.adq2465</p> <p>Given the several choices and uncertainties associated with sea-air gas flux calculations, we refrain from providing flux estimates, and encourage data users to calculate their own emission fields in a way that maximizes consistency with their chosen geophysical fields or model setup.</p>
Dark Matter from Axion Strings with Adaptive Mesh Refinement - Supplementary Animations
<p>Supplementary animations to the paper "<em>Dark Matter from Axion Strings with Adaptive Mesh Refinement </em>" (arXiv:2108.05368)</p> <ul> <li><strong>2D.mp4</strong>: 2D slices through our 3D simulation. A string segment piercing the 2D plane is tracked in the right two panels. Shown is the axion field, where the string core shows up as a discontinuity, as well as the radial mode.</li> <li><strong>Axion.mp4</strong>: The evolution of the axion energy density where the string network is overlayed in yellow. The volume spans our full simulation box with periodic boundary conditions. The relative size of a Hubble volume is indicated as well by a slowly growing smaller box.</li> <li><strong>Box.mp4:</strong> We illustrate axion radiation by focusing on a string segment. The volume shown corresponds to about 1/500th of the total simulation volume. The complex behavior of the string network can be observed with its strong influence on the axion energy density.</li> <li><strong>Strings.mp4</strong>: The evolution of the string network is shown in yellow.

Deinos Vessel All Quad Mesh 2144 Verts
Another retopo practice model. [Here](https://sketchfab.com/3d-models/deinos-vessel-798a5542100b4ed49a18917b16ff5317) is the link for the original model. The mesh is now made up of all quads and I reduced the polygon count from 137,875 Verts to 2144 Verts.  Once I retopo'd the models, I baked the color and normal data with cycles. Feel free to use the model in your projects. For giving credit, please link to [this user](https://sketchfab.com/3d-models/deinos-vessel-798a5542100b4ed49a18917b16ff5317) instead of me.

Paris catacombs: Salle Z (mesh only)
The "*Salle Z*" (Room Z) is the largest room in the catacombs. It's huge. In the 80's, people used to have underground parties there (with hundreds of people), before the main access was closed. I scanned it with 3dScannerApp. Unfortunately, I ran into processing issues (the scan was just too big IMO, > 1.2 Gb). The textured model didn't render well at all. I'm posting this mesh so people can still realize the size of the scans that the iPhone 12 Pro can possible handle (today!). The ceiling is 15 ft high. Use the Sketchfab inspector options to display a black mesh and a Matcap view. Please feel free to follow my collections of daily scans ([link](https://skfb.ly/6YuwK)) as well as my scans in San Francisco, Paris, or in the catacombs: [link](https://sketchfab.com/edemaistre/collections) Source: Objaverse 1.0 / Sketchfab
