Implemented basic SurfaceClosure compression for storing per-vertex.
...
This is really simple, and doesn't account for things like constant
parameters yet. It's just to get things rolling.

Fixed compiler warnings.

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

Improved light tree sampling and changed surface closure API.
...
Thanks to a discovery by Petra Gospodnetic during her GSOC
project, I was able to substantially improve light tree sampling
for lambert surfaces. As part of this, the part of the surface
closure API relevant to light tree sampling has been adjusted to
be more flexible.
These improvements do not yet affect GTR surface light tree
sampling.

Some refactoring in preparation for a material system.
...
The main change is that SurfaceClosures now have the hero
wavelength baked into them. Since surface closures come from
surface intersections, and intersections are always specific to
a ray or path, and rays/paths have a fixed wavelength, it doesn't
make sense for the surface closure to constantly be converting
from a more general color representation to spectral samples
whenever its used.
This is also nice because it keeps surface closures removed from
any particular representation of color. All color space handling
etc. can be kept inside the shaders.

Lambert and GTR now handle interpolated shading normals properly.
2017-07-30 23:16:03 -07:00
0481d931b9
Surface closures and light sampling now take both shading and geometric normals.
...
This will allow them to appropriately handle weirdness that comes
from the shading normal and geometric normal being different.

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

Fixed a bunch of problems that came up when running debug build.
...
The worst offender was an obvious and nasty bug in the bitstack
implementation. Hooray for debug asserts!
2017-04-14 21:37:29 -07:00

Fixed bug in GTRClosure that was resulting in all NaN outputs.
2017-03-12 00:33:36 -08:00
0b05d364e4
Added GTR surface closure.
...
Not tested yet, just a straightforward conversion from the C++
Psychopath codebase. So there are probably bugs in it from the
conversion. But it compiles!

Got rid of indexing into Float4 and 3d vector elements.
...
This assures correct semantics for SIMD usage.

Make renderer actually use the material system properly.
...
The intersection code still isn't using any kind of shading,
and materials aren't parsed by the parser, but the renderer
class itself is using them.

Fixed bugs in global illumination.
...
It was a stupid thing in the Lambert closure. It was returning
the wrong direction vector.

Beginnings of global illumination.
...
There are still some obvious bugs in it that I haven't tracked down,
so the renders aren't correct yet.
