Change to using a dedicated affine transform type.
...
This lets certain operations, especially matrix inversion, be
quite a bit faster. And we don't need anything beyond affine
transformations anyway.

Reduced the size of a hot return value.
...
Gives a small performance boost.

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.
2019-06-25 17:31:51 +09:00
630a79aca5
Initial implementation of ORST traversal.
...
This is a "just get it working" implementation. Performance
optimizations still need to be done.

Implemented a "Micropolygon Batch" type.

This is in prep for a shade-before-hit architecture. The type is
currently unused and untested.

Replaced SurfaceClosure trait with a SurfaceClosure enum.
...
Also moved surface closures to using Color internally for color
specification.
2018-12-27 22:57:44 -08:00
5add4cfdb1
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.

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.

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.
2017-10-25 06:59:35 -07:00
81c8da8113
Implemented ray intersection for RectangleLights.
...
This means that RectangleLights now work with MIS. Yay!

Changed SurfaceLight API to return the sample point on the light.
...
More specifically: prior to this, SurfaceLights returned the
shadow ray direction vector to use. That was fine, but it
kept the responsibility of generating proper offsets (to account
for floating point error) inside the lights.
Now the SurfaceLights return the world-space point on the light
to sample, along with its surface normal and error magnitude.
This allows the robust shadow ray generation code to be in one
place inside the renderer code.

Multiple importance sampling is now basically working.
...
Intersecting rectangular lights still isn't implemented, and there
are likely bugs in the MIS implementation, but it's more-or-less
working!
2017-08-16 20:04:06 -07:00

WIP: multiple importance sampling.
...
Reorganized light and surface traits so that light sources are
surfaces as well, which will let them slide easily into
intersection tests with the rest of the scene geometry.
2017-08-16 18:17:50 -07:00

WIP multiple importance sampling.
...
Added method for intersecting finite light sources, and implemented
the method for SphereLight.

Bunch of code quality improvements based on running clippy.

None of them change behavior, just make the code cleaner.

Got DistantDiscLights working! Yay!
...
This involved fixing a bug in PsychoBlend. It was including
translation in how it was transforming the sun lights' direction
vector.
2017-02-13 00:03:34 -08:00
3cbb816d4b
Added DistantDiskLight (a.k.a. sun light) parsing and data structures.
...
Also created a proper World struct in the process, to store all
infinite-extent type stuff.
Note that I goofed and did a new rustfmt pass but forgot to
commit before making these changes, so there's a lot of
formatting changes in this too. *sigh*

First renders with lighting. Yay!
...
The lighting is super crappy, and pretty much hacked in. Will
need to redo this properly soon. However, this verifies that
certain other parts of the code are (mostly) working properly.
2016-06-27 23:16:39 -07:00
6f6807009b
Prepping for adding lighting.
...
The part of the renderer responsible for light transport has been
split out into a LightPath struct. Also moving over to spectral
rendering, although it's a bit silly at the moment.
