surface_lattice_metrics.js

/* Example script demonstrating filling a triangle mesh with a gyroid.
 *
 * Usage:
 *     node examples/surface_lattice_metrics.js -t <token> -p <project>
 *
 * This is a port of the same example in the Metafold SDK for Python:
 * https://github.com/Metafold3d/metafold-python/blob/master/examples/surface_lattice_metrics.py
 *
 * Please refer to the Python example for more details.
 *
 * Note this example takes advantage of async/await in Javascript to run jobs concurrently.
