Minor code pretty-ing in the Jakob spectral upsampler.
2019-07-09 16:24:02 +09:00
70721be8e0
Moved separate functions in halton sampler inline into the match.
...
Doesn't really have much impact, but makes me feel better for some
reason.

b09f9684d1
Remove non-SIMD BVH4, and keep more bool calculations in SIMD format.
2019-06-29 07:22:22 +09:00
c5d23592b9
Keep Bool4 in its native format instead of converting to a bitmask.
...
This gives a small performance boost.
2019-06-28 22:56:51 +09:00
cd50e0dd11
Added some useful shuffle ops to Float4.
2019-06-21 22:14:18 +09:00
50f09a6134
Removed full Jakob implementation and moved table loading to build time.
...
The "light" version of Jakob still remains, which uses a much smaller
table.
2019-06-21 21:45:13 +09:00
5eeaec0a8b
Use fmadd method in Jakob spectrum eval.
2019-06-19 17:49:52 +09:00
b3cc5c070a
Added fused multiple-add method to Float4.
2019-06-19 17:45:04 +09:00
48e015996f
Initial implementation of Jakob 2019 spectral upsampling.
...
It has a slight color cast to it at the moment, I believe due to
incorrect color space conversions, not because of the upsampling
method itself. So Meng upsampling is still the active method
at the moment.
2019-06-09 19:51:43 +09:00
4aa002bb92
Reorganizing spectral upsampling crate for multiple algorithms.

ea75e3ed21
Added benchmarks for both Trifloat and Oct32 encoding/decoding.
2018-11-29 11:09:48 -08:00
a6cae26c34
Added property tests for Oct32 encoding/decoding.
...
Tests random vectors, and makes sure that encoding/decoding
round trip only introduces precision errors below a certain
threshold.
Pretty confident that the implementation is correct now.
2018-11-29 09:50:38 -08:00
8e15dba29d
Implementation of the Oct32 encoding of unit vectors.
...
The code still needs testing, but initial toying around suggests
that it's working correctly.
2018-11-28 23:41:12 -08:00
c0cb071251
Further optimizations to the trifloat implementation.

Use bit fiddling to avoid some expensive operations in trifloat encoding/decoding.
2018-11-23 22:31:28 -08:00
3d1ade21c2
Better naming for the trifloat functions.
2018-11-23 21:38:27 -08:00
3fb22fdefa
Implemented a "tri-float" encoding, similar to RGBE.
...
This implementation trades less range for more precision, giving
9 bits to each mantissa instead of just 8 bits as in RGBE.
2018-11-23 20:01:15 -08:00
498c1ea8d9
Running latest rustfmt. No functional change.

2018-07-01 16:49:41 -07:00
3f55df7225
Some basic SIMD optimizations for XYZ->Spectrum conversion.
2018-07-01 15:50:34 -07:00
ef7084e694
Reorganized xyz_spectra crate a bit.
...
This way the executable code can be worked with directly, instead
of via the python file that generates the rust code.
Also introduced some small optimizations.
2018-07-01 14:29:19 -07:00
6d21a30840
Formatting with newer cargo fmt.
...
No meaningful code change, only formatting.
2018-06-24 21:18:10 -07:00
df27f7b829
Moved matrix transpose and inverse code into Float4 crate.
...
This allows for more optimized implementations, taking advantage
of SIMD intrinsics.
2018-06-24 21:06:32 -07:00
8e791259b3
Sped up Float4::h_sum for platforms with SSE3.
...
Since this is used heavily during matrix multiplication, gives a
nice little speed boost.
2018-06-24 16:45:21 -07:00
27d1b2286b
Switch to stable SIMD intrinsics.
...
Rust 1.27 stablized a variety of cpu intrinsics, including SIMD
on x86/64 platforms. This commit moves to using those intrinsics
for the optimized Float4 implementation. This means Psychopath
now compiles on stable Rust with all optimizations. Yay!
2018-06-24 15:32:09 -07:00
bbf832a3d8
Fixed compile error in float4 lib, and updated to latest simd crate.
