Replaced SurfaceClosure trait with a SurfaceClosure enum.
...
Also moved surface closures to using Color internally for color
specification.

Fixed the Planck's Law implementation to use correct units.
...
Color temperature specified colors now work!

Implementing Color as a simple enum rather than as a trait.
...
There's really no reason for it to be a Trait, and this will simplify
a lot of things down the road.

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

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.

Moved more work out of the triangle mesh intersection inner loop.
...
This makes the code a bit spaghetti-like, but it provides noticable
speed-ups in the all the scenes I tested.

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.

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!

Fixed sampling of very small rectangle lights.
...
The sampling method used before is numerically unstable for very
small lights. That sampling method is still used for large/close
lights, since it works very well for that. But for small/distant
lights a simpler and numerically stable method is used.

Make MIS routines handle infinite importance better.
...
Handle it like the limit case: as A approaches infinity, the
limit approaches 1.0. Before this, we were getting NaN values.
This fixes that.

Whoops, nope. The last commit was a mistake.
...
It *seemed* to fix the problem I was running into, but it actually
made the SphereLight ray intersection code incorrect, and wa just
avoiding intersections that should have happened.
I should test better before committing. :-)

Stupid bug in SphereLight ray intersection code.
...
The ray origin wasn't transformed into local space, resulting in
silly problems.
