craters() produces a cratered spherical surface according to optional user inputs that control
  • sphere size and location
  • number and distribution of craters
  • crater radii and depths
By default, crater radii are selected randomly from a bounded gamma distribution. Crater depths are a function of crater radii so larger craters create larger impacts. Crater profiles are defined by a logistic function.
craters outputs the 3D coordinates to the surface object, a table of crater information, and handles to graphics objects.
See the example file for a survey of capabilities of the craters function.
