Produces 360 images

This uses --animate which doesn't work with more than 3 frames when running in a docker container spuder/openscad-dockerhub#2

openscad /dev/null -D '$vpt = [0,0,0];' -D '$vpd = 20; $vpr = [0,$t * 360,0];' -o 'foo.png' -D 'cube([2,3,4]);' --imgsize=250,250 --animate 360 --colorscheme "Tomorrow Night"

The following all work, but not very well

parse erb templates from command line (standalone, cli, json)

Goal

  • provide cli command to render erb template
  • template params (bindings) to be provided using json format
  • use inputs from file (template.erb, params.json)
  • use inputs from cli options / parameters
  • render output to stdout OR to file

Why ?
