Import yt from yt.units import kpc ds = yt. If you don’t want to do this, you can also supply it asĪn argument to the function export_sketchfab. ~/.config/yt/yt.toml file under the heading as the variable Once you’ve obtained it, put it into your You can get this API key byĬreating an account and then going to your “dashboard,” where it will be listed The YTSurface object includes a method to upload directly to Sketchfab,īut it requires that you get an API key first. Model in a website with other supplemental data, or you can use Sketchfab toĭiscuss morphological properties of a dataset with collaborators. People can explore and see what the data looks like. You’re looking at a galaxy formation simulation and you publish a paper, youĬan include a link to the model in that paper (or in the arXiv listing) so that There are lots of reasons to want to export to Sketchfab. These models can be embedded in websites.

Plus, it means that you can share data withĪnyone and they can view it immersively without having to download the data orĪny software packages! Sketchfab provides a free tier for up to 10 models, and New technology for displaying 3D graphics in any browser. Sketchfab is a website that uses WebGL, a relatively Source data object and a field over which to identify a surface at a given You can create one of these objects by specifying a Parallelism in yt, see Parallel Computation With yt.Īlternatively, you can make an object called YTSurface that makes To extract geometry or sample a field, callīoth of these operations will run in parallel.

ItĪlso means you can export a surface from yt and view it in something likeīlender, MeshLab, or even on your Android or iOS device in Isocontour in density and calculate the mass flux over that isocontour. This means you can, for instance, extract an

Surfaces can be exported in OBJ format, values can be samplesĪt the center of each face of the surface, and flux of a given field could beĬalculated over the surface. Perform such an operation, and so there will be seams visible in 3D views of “crack-fixing” step is applied to match up these boundaries. This means that with adaptive mesh refinementĭata, you will see cracks across refinement boundaries unless a That density, it will include both of the clumps. Two clumps of a given density in your data object and extract an isocontour at In fact, inside a given data object, the marching cubes algorithm will returnĪll isocontours, not just a single connected one.

Note that these isocontours are not guaranteed to be topologically connected. The second piece ofįunctionality is to calculate the flux of a field over an isocontour. Isocontours and return either the geometry of those isocontours or to returnĪnother field value sampled along that isocontour. Yt contains an implementation of the Marching Cubes algorithm, which can operate onģD data objects. Surface Objects and Extracting Isocontour Information ¶
