2022-04-19*: s/til_fb_fragment_zero/til_fb_fragment_clear/Vito Caputo
Mechanical renaming of "zero" to "clear" throughout for this context.
2022-03-30*: wire up context-specific setup instancesVito Caputo
This is a preparatory commit for cleaning up the existing sloppy global-ish application of settings during the iterative _setup() call sequences. Due to how this has evolved from a very rudimentary thing enjoying many assumptions about there ever only being a single module instance being configured by the settings, there's a lot of weirdness and inconsistency surrounding module setup WRT changes being applied instantaneously to /all/ existing and future context's renderings of a given module vs. requiring a new context be created to realize changes. This commit doesn't actually change any of that, but puts the plumbing in place for the setup methods to allocate and initialize a private struct encapsulating the parsed and validated setup once the settings are complete. This opaque setup pointer will then be provided to the associated create_context() method as the setup pointer. Then the created context can configure itself using the provided setup when non-NULL, or simply use defaults when NULL. A future commit will update the setup methods to allocate and populate their respective setup structs, adding the structs as needed, as well as updating their create_context() methods to utilize those setups. One consequence of these changes when fully realized will be that every setting change will require a new context be created from the changed settings for the change to be realized. For settings appropriately manipulated at runtime the concept of knobs was introduced but never finished. That will have to be finished in the future to enable more immediate/interactive changing of settings-like values appropriate for interactive manipulation
2022-03-19*: drop til_module_t.licenseVito Caputo
Originally the thinking was that rototiller modules would become dlopen()ed shared objects, and that it would make sense to let them be licensed differently. At this time only some modules I have written were gplv3, Phil's modules are all gplv2, and I'm not inclined to pivot towards a dlopen model. So this commit drops the license field from til_module_t, relicenses my v3 code to v2, and adds a gplv2 LICENSE file to the source root dir. As of now rototiller+libtil and all its modules are simply gplv2, and anything linking in libtil must use a gplv2 compatible license - the expectation is that you just use gplv2.
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.
