2017-09-13ray: cleanup ray_camera_frame_t fragmentsVito Caputo
Previously every fb_fragment_t (and thus thread) was constructing its own ray_camera_frame_t view into the scene, duplicating some work. Instead introduce ray_camera_fragment_t to encapsulate the truly per-fragment state and make ray_scene_render_fragment() operate on just this stuff with a reference to a shared ray_camera_frame_t prepared once per-frame. Some minor ray_camera.c cleanups sneak in as well (prefer multiply instead of divide, whitespace cleanups...)
2017-06-02ray: plumb depth and camera to objectsVito Caputo
To enable prepare to precompute aspects of primary rays which all have a common origin at the camera, bring the camera to ray_object*_prepare() and bring the depth to ray_object*_intersects_ray() for primary ray detection. This is only scaffolding, functionally unchanged.
2017-06-01ray: perform ambient light color scale in prepareVito Caputo
Trivially removes a ray_3f_mult_scalar() from the hot path.
2017-05-12ray: add ray_scene_prepare() object precomputingVito Caputo
Just embed a _prepared struct in the object where precomputed stuff can be cached. Gets called once before rendering, which ends up calling the object-specific ray_object_$type_prepare() methods per object.
2017-04-22ray: remove vestigial ray_threads codeVito Caputo
Now that rototiller is generally threaded when a prepare_frame() method is supplied, and modules/ray has been updated accordingly, discard the now redundant ray-specific threading code and related stuff.
2017-01-18*: move source into src/ subdirVito Caputo
Restoring some organizational sanity since adopting autotools.
