Removed full Jakob implementation and moved table loading to build time.

The "light" version of Jakob still remains, which uses a much smaller
table.

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.

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.

Implementation of the Oct32 encoding of unit vectors.
...
The code still needs testing, but initial toying around suggests
that it's working correctly.

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.

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!

Created crate for BVH node traversal order calculations.

Might move this into the main source base at some point, but
I'm not totally sure about the correctness of the table yet, so
would like to generate it for now.

Split colorspace transform functions out into their own crate.
...
They are now generated by a build.rs script from nothing but the
colorspace's primaries, which makes it super easy to add more
colorspaces. So easy that I added three more: ACES AP0, ACES AP1
and Rec.2020.
This lays the foundation for supporting output to different
colorspaces.

Removed blue noise dithered sampling.
2017-05-14 12:37:01 -07:00
d71fd3b5c8
Implemented blue noise dithered sampling. Temporary.
...
After implementation, it does appear to make rendering slower
by a noticable bit compared to what I was doing before. At very
low sampling rates it does provide a bit of visual improvement,
but by the time you get to even just 16 samples per pixel its
benefits seem to disappear.
Due to the slow down and the minimal gains, I'll be removing
this in the next commit. But I want to commit it so I don't
lose the code, since it was an interesting experiment with
some promising results.
