2021-10-01*: librototiller->libtilVito Caputo
Largely mechanical rename of librototiller -> libtil, but introducing a til_ prefix to all librototiller (now libtil) functions and types where a rototiller prefix was absent. This is just a step towards a more libized librototiller, and til is just a nicer to type/read prefix than rototiller_.
2021-02-14*: split rototiller.[ch] into lib and mainVito Caputo
This is a first approximation of separating the core modules and threaded rendering from the cli-centric rototiller program and its sdl+drm video backends. Unfortunately this seemed to require switching over to libtool archives (.la) to permit consolidating the per-lib and per-module .a files into the librototiller.a and linking just with librototiller.a to depend on the aggregate of libs+modules+librototiller-glue in a simple fashion. If an alternative to .la comes up I will switch over to it, using libtool really slows down the build process. Those are implementation/build system details though. What's important in these changes is establishing something resembling a librototiller API boundary, enabling creating alternative frontends which vendor this tree as a submodule and link just to librototiller.{la,a} for all the modules+threaded rendering of them, while providing their own fb_ops_t for outputting into, and their own settings applicators for driving the modules setup.
2021-01-17plato: regular convex polyhedrons in 3DVito Caputo
plato implements very simple software-rendered 3D models of the five convex regular polyhedra / Platonic solids Some TODO items: - procedurally generate vertices at runtime - add hidden surface removal setting (Z-buffer?) - add flat shaded rendering setting - add gouraud shading, maybe phong too? - show dual polyhedra This was more about slapping together a minimal 3D wireframe software renderer than anything to do with polyhedra, convex regular polyhedra just seemed like an excellent substrate since they're so simple to model.
