Changed ray batch data access to be through methods.
...
This is (potentially) just temporary. It's to make it a bit easier
to play with data layout to see how that affects performance.

Type alias for the ray index type.
...
Makes things easier to play with.

630a79aca5
Initial implementation of ORST traversal.
...
This is a "just get it working" implementation. Performance
optimizations still need to be done.

Improve module path usage and remove extern crate declarations where possible.

Formatting with newer cargo fmt.
...
No meaningful code change, only formatting.

Fix compiler warnings.

Run new rustfmt on codebase.

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

Instrument code to count ray/node tests during BVH traversal.

Implemented a non-SIMD BVH4. Perf appears to be identical to BVH.

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.

Fixed bug in new BVH4 traversal code.

Print stats for BVH and BVH4 traversal, and working on speeding up BVH4 traversal.

Eliminated some unnecessary left drift in BVH4 code.
...
IMO this is much easier to read.

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.
2017-04-16 17:22:51 -07:00
2c4f103db5
Factored some calculations into the outer loop of BVH4 traversal.
...
Provides a small but noticable speed boost.
2017-04-16 00:51:13 -07:00

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.
2017-04-14 20:25:12 -07:00

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

Added some dev printing info.

Got BVH4 working. Woo hoo!

Completed first attempt at implementing BVH4.
...
Completely untested, so almost certainly non-functional. But it
compiles!

Beginnings of BVH4 implementation.
...
- Created a traversal-order table.
- Created a function to help index into that table.
2017-04-11 23:10:54 -07:00
a2d7f9e149
Added BBox4 and BVH4 types.
...
BVH4 is just a skeleton (duplicated BVH) right now. But BBox4
is complete (pending testing).
