Unable to export shape from pure guile

[Kreyren]

Description

Using the code:

(define-module (some cool module)
  #:use-module (libfive shapes)
  #:use-module (libfive transforms)
  #:use-module (libfive csg)
  #:use-module (libfive text))

(difference (sphere 1 [0 0 0])
  (sphere 0.6 [0 0 0])
  (cylinder-z 0.6 2 [0 0 -1])
  (reflect-xz (cylinder-z 0.6 2 [0 0 -1]))
  (reflect-yz (cylinder-z 0.6 2 [0 0 -1])))
; => Shape

I am unable to export the STL file..

In C++ there seems to be an API to use Mesh::render(out, bounds)->saveSTL("sphere.stl"); to get the STL file from the shape, but i can't find the guile eqvivalent to this feature without using Studio that seems to be reinterpreting the guile code to C++

Versions

• Operating system: GNU Guix (ba8679fb2452f4466a98a99edf050ea7452c83f4)
