c0a26819c6 Bunch of code quality improvements based on running clippy.
None of them change behavior, just make the code cleaner.

f371e0643a Instrument code to count ray/node tests during BVH traversal. 2017-07-06 22:17:36 -07:00
09daf617ef Implemented a non-SIMD BVH4. Perf appears to be identical to BVH. 2017-07-01 15:08:05 -07:00
172e2f19ef Removed BVH4 and the related bitstack from AccelRay.
I couldn't make the BVH4 faster than the BVH, and the bitstack
was bloating the AccelRay struct.  Removing the bitstack gives
a small but noticable speedup in rendering.

b135e8beb8 Fixed bug in new BVH4 traversal code. 2017-04-22 22:32:36 -07:00
fdf2b4babf Print stats for BVH and BVH4 traversal, and working on speeding up BVH4 traversal. 2017-04-22 11:18:29 -07:00
725bbca6a1 Eliminated some unnecessary left drift in BVH4 code.
IMO this is much easier to read.

92fd83a766 Actually using the None match arm in BVH4 traversal now.
It seems to maybe be just a hair faster.  But, also, it sets the
code up to try some more optimizations.

2c4f103db5 Factored some calculations into the outer loop of BVH4 traversal.
Provides a small but noticable speed boost.

a6d8de43d7 Make BVH4 calculate and store its node count.
Useful for debugging.

44e3ee8b4b Fixed nasty bug in BVH4 building.
In practice it worked fine, but only by accident.  NaN's were
being passed to the lerp_slice function, which led to the
correct result in this case but is icky and dependant
on how lerp_slice is implemented.

7f761a9489 Added custom aligned allocations to MemArena.
Used in BVH4.

8b1e3a3cdb Added some dev printing info. 2017-04-13 22:50:47 -07:00
573c5da5ab Got BVH4 working. Woo hoo! 2017-04-13 22:44:34 -07:00
53a14996c9 Completed first attempt at implementing BVH4.
Completely untested, so almost certainly non-functional.  But it
compiles!

e0c6dfbd76 Beginnings of BVH4 implementation.
- Created a traversal-order table.
- Created a function to help index into that table.

a2d7f9e149 Added BBox4 and BVH4 types.
BVH4 is just a skeleton (duplicated BVH) right now.  But BBox4
is complete (pending testing).
