Manually emplace a single crater on the Moon and visualize it with PyVista

By David Minton

This example shows how to emplace a single large crater on the Moon using Cratermaker’s Simulation.emplace() method. The crater is defined with a specific diameter and location. The final surface is exported and visualized using PyVista.
