Cartesian Gravity Well

open OCADml
open OSCADml

Define a function from x and y coordinates to z height of the xy plane.

let gravity_well ~x ~y =
  let z = 50. -. (50. /. Float.sqrt ((x *. x) +. (y *. y))) in
  if z < 1. then 1. else z

Evaluate gravity_well, producing a mesh with the resulting height at each point of the grid defined by the xy bound and step parameters.

let mesh =
  Mesh.cartesian_plot
    ~min_x:(-10.)
    ~x_steps:30
    ~max_x:0.
    ~min_y:(-10.)
    ~y_steps:60
    ~max_y:10.
    gravity_well

Convert our mesh into an OpenSCAD polyhedron and output to file.

let () = Scad.to_file "cartesian_gravity_well.scad" (Scad.of_mesh mesh)
