6d21a30840 Formatting with newer cargo fmt.
No meaningful code change, only formatting.

5a03a46ac7 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!

c0a26819c6 Bunch of code quality improvements based on running clippy.
None of them change behavior, just make the code cleaner.

f371e0643a Instrument code to count ray/node tests during BVH traversal. 2017-07-06 22:17:36 -07:00
09daf617ef Implemented a non-SIMD BVH4. Perf appears to be identical to BVH. 2017-07-01 15:08:05 -07:00
011405e131 Implemented robust ray origin calculation for bounced rays.
We take a small performance hit for this, but given that it's
making things meaningfully more correct I feel like it's more
than worth it.

b8321beaad 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.

2a66485595 Supress information output when doing serialized ouput for PsychoBlend. 2017-06-10 22:34:14 -07:00
71c320d87c Added command-line argument to render an image cropped. 2017-06-06 21:11:35 -07:00
59555f67f9 PsychoBlend: use stdin/out to transfer scene data by default.
This eliminates writing temp files to disk for any part of the
Blender/Psychopath integration.

The option to export to a file still exists, however, by
specifying an export output path.
2017-06-04 23:24:45 -07:00
f84d093f66 PsychoBlend now updates render in realtime within Blender.
Also, cancelling renders is much more responsive now, especially
during long exports.

3beffab507 Update to latest openexr-rs, and switch to pure Rust PNG output crate. 2017-05-28 17:51:01 -07:00
f0604a69ae Updated to latest openexr crate, and switched to 16-bit float EXR's. 2017-05-20 23:48:01 -07:00
922e33ec3f Reformat code with latest rustfmt and custom config. 2017-05-14 13:43:51 -07:00
567b658b6c Removed blue noise dithered sampling. 2017-05-14 12:37:01 -07:00
d8a33c7bfa Added a blue noise mask generator as a sub-crate. 2017-05-13 03:23:55 -07:00
172e2f19ef Removed BVH4 and the related bitstack from AccelRay.
I couldn't make the BVH4 faster than the BVH, and the bitstack
was bloating the AccelRay struct.  Removing the bitstack gives
a small but noticable speedup in rendering.
2017-05-12 21:07:40 -07:00
88578b9eae Moved Float4 and Matrix and Vector math into their own sub-crates. 2017-05-12 21:01:54 -07:00
b698a52f6c Split some more things out into sub-crates.
Also translated the Halton generator to rust and made it a crate
where the code is generated by a build.rs file.
2017-05-11 22:57:59 -07:00
a3a19e53ef Some misc small optimizations. 2017-05-11 01:22:37 -07:00
0cbf851451 Fixed a commandline argument that was broken.
Also removed a redundant statistics printout.

fdf2b4babf Print stats for BVH and BVH4 traversal, and working on speeding up BVH4 traversal. 2017-04-22 11:18:29 -07:00
8b14e46bc1 Added more detailed render stats. 2017-04-22 10:31:27 -07:00
7d5bda2a3b Print newline before exit.
Makes it easier to scan commandline history for multiple renders.
2017-04-14 23:22:38 -07:00
8b1e3a3cdb Added some dev printing info. 2017-04-13 22:50:47 -07:00
a2d7f9e149 Added BBox4 and BVH4 types.
BVH4 is just a skeleton (duplicated BVH) right now.  But BBox4
is complete (pending testing).
2017-04-11 14:22:11 -07:00
c05bae2636 Created a BitStack128 type and added it to Ray.
This will be used for BVH4 traversal.
2017-04-11 11:13:23 -07:00
f5ba119562 Switched to clap for command line argument parsing. 2017-04-11 10:15:32 -07:00
d9564bc005 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.
2017-04-10 23:41:38 -07:00
db3e4ad129 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.
2017-04-10 20:49:55 -07:00
70f715ec2d 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.
2017-04-10 18:34:08 -07:00
6623443e2e Improved .psy file parsing error messages.
Biggest improvement: it gives you line numbers.  But also progress
on better descriptions.
2017-04-10 14:03:01 -07:00
57aa9be496 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.
2017-04-09 17:31:17 -07:00
f4445417dc Reorganizing the module tree.
Enough things had accumulated that it seemed to make sense to
group some stuff together.  So here it is.
2017-02-14 00:14:08 -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*

0e8d708ff0 Made samples per bucket configurable. 2016-10-16 14:55:00 -07:00
bb4e57795f Added support for OpenEXR output. 2016-10-09 20:34:58 -07:00
c71b00ca31 LightTree now works with lights in hierarchical instancing. 2016-08-21 00:19:43 -07:00
97b5ef77f8 Code cosmetics: organize and alphabetize crate/mod/use statements. 2016-08-20 18:10:55 -07:00
f75c0c78fe Moved TransformStack into its own module.
It's clear at this point that it will be useful outside of Tracer.
2016-08-20 17:43:26 -07:00
c997c55739 Separate timing of rendering and image writing in print out. 2016-08-20 16:25:12 -07:00
cf49cdbb02 Moved int hash functions into own file, and use in quick_select(). 2016-08-14 16:03:17 -07:00
fbeadfce29 Use quick select for balanced BVH building.
This gets rid of a crate dependency, and also is faster.
2016-08-14 00:51:21 -07:00
08576b9934 Cleaned up console output. 2016-07-31 12:27:06 -07:00
c6f6266a38 Added timer output so you can see how long things take. 2016-07-31 12:05:28 -07:00
