* Precompute objects in dmnsn_raytrace_scene() rather than dmnsn_new_prtree().Tavian Barnes2010-05-301-0/+6
|
* New dmnsn_new_thread() function.Tavian Barnes2010-05-091-23/+11
| | | | | | | Two advantages: first, waiters are guaranteed to wake if a dmnsn_error() cancels a thread. Second, the thread library is fully abstracted over by threads.{c,h} and progress.{c,h} now, though raytrace.c is still using pthread_create() directly.
* New DMNSN_ARRAY_FOREACH() macro, faster than iterating with dmnsn_array_get().Tavian Barnes2010-05-081-7/+3
|
* Use C99 for loop initializers.Tavian Barnes2010-05-051-13/+9
|
* Replace BVSTs with priority R-trees.Tavian Barnes2010-05-051-21/+10
|
* Fix some includes.Tavian Barnes2010-04-271-0/+1
|
* Don't render transparent shadows with transparency off.Tavian Barnes2010-04-171-1/+2
|

* Don't use dynamic memory for dmnsn_intersection's.Tavian Barnes2010-04-071-14/+10
| | | | Drops us from ~400,000 allocs to ~1000. Oops ><.
* New dmnsn_malloc() function, and friends.Tavian Barnes2010-04-071-88/+37
| | | | | | I'm tired of checking for malloc failures everywhere, considering it never happens. So just bail out whenever it does. A lot of stuff is guaranteed to succeed if it returns now.

* Separate finishes into single-purpose finishes.Tavian Barnes2009-12-231-3/+5
|
* Fix progress calculation in raytracing.Tavian Barnes2009-11-201-1/+1
|
* Use dmnsn_new_*() rather than dmnsn_*_construct().Tavian Barnes2009-11-191-6/+3
|
* Refactor raytrace.c a bit.Tavian Barnes2009-11-191-56/+81
|

* Make finish callback a propper BRDF.Tavian Barnes2009-11-171-24/+31
|
* Raytrace one row of pixels per thread.Tavian Barnes2009-11-091-5/+2
| | | | | | The theory is that if the next ray shot is closer to the previous ray, the k-D splay tree will work better because we're more likely to hit the same object.
