2019-11-10rototiller: add rototiller_module_t.setup()Vito Caputo
Wire up support for module settings, yes it's that small a change. I've forward-declared the settings related types in rototiller.h, if a module wants to actually wire up the .setup() method they'll need to include settings.h.
2017-12-10rototiller: introduce module.finish_frame()Vito Caputo
Add a hook for post-render serialized frame completion, some of the renderers may have state to cleanup after rendering a frame. A future commit may change add a return value to control flow for features like multi-pass rendering within a given module. The raytracer for example may want to add concurrently executed post filters, and having a non-void return from finish_frame() would be a tidy way to tell rototiller "go back to prepare->render for this context" as many times as necessary, keeping the pass state in the context. For now its return is void however, as I just need a cleanup hook as the raytracer becomes more stateful per frame with a BIH spatial index in the works.
2017-09-14*: use fragment generatorVito Caputo
Rather than laying out all fragments in a frame up-front in ray_module_t.prepare_frame(), return a fragment generator (rototiller_fragmenter_t) which produces the numbered fragment as needed. This removes complexity from the serially-executed prepare_frame() and allows the individual fragments to be computed in parallel by the different threads. It also eliminates the need for a fragments array in the rototiller_frame_t, indeed rototiller_frame_t is eliminated altogether.
2017-04-22*: add module context machineryVito Caputo
introduces create_context() and destroy_context() methods, and adds a 'void *context' first parameter to the module methods. If a module doesn't supply create_context() then NULL is simply passed around as the context, so trivial modules can continue to only implement render_fragment(). A subsequent commit will update the modules to encapsulate their global state in module-specific contexts.
2017-04-22rototiller: add prepare_frame & rototiller_frame_tVito Caputo
Undecided on wether rototiller_frame_t should be fb_frame_t or not, may change later.
2017-04-22*: /render/render_fragment/ in rototiller_module_tVito Caputo
Adding more context to the name in anticipation of adding a prepare_frame() method to the module struct.
2017-04-21*: s/renderer/module/gVito Caputo
Make consistent with the source directory structure naming.
2017-01-18*: move source into src/ subdirVito Caputo
Restoring some organizational sanity since adopting autotools.
