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.
2017-04-27sparkler: enable rudimentary threaded renderingVito Caputo
This moves most of the particle system maintenance into the serially executed sparkler_prepare_frame(), divides the frame into ncpus fragments, and leaves the draw to occur concurrently. The drawing must still currently process all particles and simply skips drawing those falling outside the fragment. Moving more of the computation out of prepare_frame() and into render_fragment() is left for future improvements, as it's a bit complex to do gainfully.
2017-04-26sparkler: utilize context struct for module stateVito Caputo
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.
2017-04-22*: /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.
2017-02-03*: use fb_fragment_zero() instead of memset()Vito Caputo
2017-01-18*: move source into src/ subdirVito Caputo
Restoring some organizational sanity since adopting autotools.
