Refactor and rework of BVH.
...
The BVH building code is now largely split out into a separate
type, BVHBase. The intent is that this will also be used by
the BVH4 when I get around to it.
The BVH itself now uses references instead of indexes, allocating
and pointing directly into the MemArena. This allows the nodes
to all be right next to their bounding boxes in memory.

MemArena now slowly increases the size of each subsequent block.
...
This seems to work more nicely than a fixed block size, because
it adapts to how much memory is being requested over-all. For
example, a small scene won't allocate large amounts of RAM,
but a large scene with large data won't be penalized with a
lot of tiny allocations.

MemArena now collects statistics about its usage.

You can print out statistics about the main arena used in
Psychopath by passing the new --stats flag.

on better descriptions.

First steps towards using the memory arena allocator.
...
Changed Camera to us the memory arena allocator, and worked out a
bunch of stuff through doing that.

Made MemArena so it will actually work for multiple allocations.

Silly mistake.

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!

Reorganizing the module tree.

Enough things had accumulated that it seemed to make sense to
group some stuff together. So here it is.

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*

Changed LightTree traversal to be a bit better in its choices.
...
After some experimentation, it's pretty clear that the LightTree
performs a lot better with a model of spherical _volume_ light
sources. This makes sense considering that generally they
represent a distribution of other lights in space.
This is a quick hack to make it behave a bit more like that. But
the long-term solution will be to adjust how
estimate_eval_over_solid_angle() of surface closures is implemented.
2016-08-21 15:27:15 -07:00
7f1ab59c5e
Implemented alternative SAH split that uses off-axis split planes.
...
It doesn't seem to actually perform better, generally, but I'm
leaving it in for future reference for other things.

Minor optimization in the transform stack.

unsafe code.
