Quicksand: Lightweight Probabilistic Programming Implemented in Terra (2014) [pdf]

I am trying to see how the procedural model generation of this paper stacks up against Rosetta [1], which I intermittently use with Racket [2] to do procedural geometry generation for computational design, sculptural, architectural, game dev, and other endeavors. It seems lengthier, but more diverse in its iterations.

I am hoping to leverage my early C programming with newly-found Terra, and Lua to allow me to move across legacy low-level, meta-programmable low-level, and scripting for the many things I play around with, even creating DSLs. I've used Grasshopper in Rhino, and others, but I like staying away from having an AutoCAD or Rhino license, and just use code. I need to make another backend target for Rosetta other than OpenGL. FreeCAD [3] is my current target, so I can create some type of geometry for the CAD folk, and 3D printing. I really like Lisp, so Racket and Rosetta tick a box for that, but I am now thinking I can use Terra/Lua/Fennel [4] for a toolchain. It's easy to hook into FreeCAD's API using C++ or Python, which is uses and has a terminal for in the GUI. Maybe Fennel terminal in FreeCAD?
