Added command-line argument to render an image cropped.

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.
2017-06-03 00:00:19 -07:00
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.
2017-04-22 12:50:28 -07:00
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*
2017-02-12 20:29:08 -08:00
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
1f94791b6b
Moved SAH splitting code into its own function.
...
This is in prep for the light tree, where we'll want to use that
code.
2016-07-30 21:20:01 -07:00
e4c94d0c58
Optional use of SIMD intrinsics, via feature in cargo.
...
This is disabled by default right now, because it only builds on
nightly.
2016-07-16 19:58:39 -07:00
ec75f11206
Render buckets in hilbert curve order.
...
Provides a slight speed-up.
2016-07-16 14:53:03 -07:00
35ef58b09c
Special case BVH building when we get too close to max depth.
...
This avoids exceeding max BVH depth even in pathological cases.
Still need improve non-worst case building, but this at least
prevents crashes in worst case.
2016-07-16 00:05:23 -07:00
5b461220a5
PsychoBlend now exports meshes as meshes, and Psychopath renders to PNGs.
2016-07-10 17:42:28 -07:00
5df583c2d0
Multiple light sources are now handled.
2016-07-10 00:10:49 -07:00
e56ac418da
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.
2016-07-03 01:18:50 -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.
2016-06-26 23:08:24 -07:00
1cbf20e67f
Beginnings of light sources. Yay!
2016-06-19 14:32:13 -07:00
18245b725c
All final intersections are now done in world space.
...
BVH traversal still happens in local space, but final actual
surface intersection calculations are done in world space by
transforming the triangle into world space. This is to improve
numerical consistency between intersections.
2016-06-09 01:04:12 -07:00
890c04c44a
Added XYZ color spectrum sampling code.
...
This will be critical for spectral rendering, whenever I get
around to it.
2016-06-07 08:14:19 -07:00
0b5a3de2dd
Added command line flag to set number of render threads.
2016-06-05 10:08:27 -07:00
5ec1f534cf
Implemented bucketed rendering.
2016-06-05 01:27:55 -07:00
