OpenSCAD Minecraft ModelRenderer Modules v2

This emulates the Minecraft ModelRenderer and modelling system, featuring child body part management, animation (sort-of), and a robust environment to work in. All the documentation is in the file. More changes are soon to come.

New in v2, hand held item rendering. Provide a set of coordinates for the pixels of the item model and away it'll go. Also comes pre-packed with a Sword and a Stick model.
