Gallery¶

Each example runs a component, or a pipeline of them, on one of the example meshes, from the current code: CI runs them again whenever the code they depend on changes (docs/gallery/examples.yaml).

The input is on the left, the output on the right. Drag to rotate, scroll to zoom, right-drag to pan. On a tet mesh, the cut hides the tets on one side of a plane: pick its axis and move it with the slider. Cells are colored by element quality (the AMIPS energy, on a log scale from the mesh's best element to its worst) or by region; the faces of a tet mesh's boundary are gray.
