Added more detailed render stats.

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!

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.

4a86c4122a
Laying some groundwork for a simple shading system.
2017-03-14 00:27:25 -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.

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*
2017-02-12 20:29:08 -08:00
0e8d708ff0
Made samples per bucket configurable.
2016-10-16 14:55:00 -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
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
08576b9934
Cleaned up console output.
2016-07-31 12:27:06 -07:00
ec75f11206
Render buckets in hilbert curve order.
...
Provides a slight speed-up.
2016-07-16 14:53:03 -07:00
5bc97f69b8
Actually use the background color from the scene file.
2016-07-16 13:54:41 -07:00
8cd445813a
Removed some dead code.
2016-07-16 13:36:34 -07:00
c2eb421fd8
Actually use seed in renders.
...
This is important for animations, where you don't want the same
noise pattern every frame.
2016-07-10 17:56:42 -07:00
e4f9a54e48
Leave console output on a newline.
2016-07-10 17:47:28 -07:00
5b461220a5
PsychoBlend now exports meshes as meshes, and Psychopath renders to PNGs.
2016-07-10 17:42:28 -07:00
e8ee371423
Silence some warnings.
2016-07-10 16:46:14 -07:00

Print render progress and auto-determine bucket size.
...
The bucket size is automatically determined based on a target
number of samples per bucket.
2016-07-10 16:40:30 -07:00
5df583c2d0
Multiple light sources are now handled.
2016-07-10 00:10:49 -07:00
0880a0f19d
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.
2016-07-07 19:51:19 -07:00
543f2719e4
Fixed bugs in global illumination.
...
It was a stupid thing in the Lambert closure. It was returning
the wrong direction vector.
2016-07-04 11:54:46 -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
6e8f0894fd
Image struct can now dole out buckets in a thread-safe way.
...
This avoids the whole-image locking that was being done before,
which was causing a lot of thread contention.
2016-07-02 16:27:19 -07:00
02a0740cac
More proper use of light sources.
2016-07-01 00:00:38 -07:00
f927dd0d46
Silencing a bunch of compiler warnings.
2016-06-29 15:23:07 -07:00
f1df7a3b1a
Slight tweak to how ray offsets are done.
2016-06-29 15:00:44 -07:00
52acee33af
Implemented rectangular area lights.
...
Also added Cornell Box test scene.
2016-06-29 14:30:42 -07:00

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.
2016-06-26 23:08:24 -07:00
d14e2c93b7
Converted Image over to store renders in XYZ colorspace.
2016-06-18 18:08:35 -07:00

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
5ec1f534cf
Implemented bucketed rendering.
2016-06-05 01:27:55 -07:00
a681ba461e
Implemented basic multi-threaded rendering.
...
It's a bit inefficient because a thread is spawned for each pixel.
Need to implement bucketing.
2016-06-03 21:03:04 -07:00
039943e0cb
Auto-formatting code with new version of rustfmt.
2016-06-02 22:43:35 -07:00
56b5267b7a
Fixed incorrect rendering angle.
...
The problem was in how the camera rays were generated.
2016-05-28 13:05:16 -07:00
99dc371a75
Beginnings of a mesh parser. Also cleaned up some unused imports.
2016-05-25 08:16:05 -07:00
f6891173eb
Moved ray tracing responsibilities to the Tracer.
...
This is still pretty WIP, but it at least gets the functionality
back to where it was before.
2016-03-13 13:01:10 -07:00
e96798ab6b
Lazily committing a bunch of stuff.
...
Includes:
- More scene parsing code. Making good progress!
- Making the rendering code actually use the Scene and Assembly
types.
- Bare beginnings of a Tracer type.
2016-03-12 00:33:11 -08:00
38d33ed144
More work on scene parsing.
...
Using Nom to help with parsing the contents of leaf nodes.
2016-03-10 23:58:19 -08:00
907d15f643
Started creating an interface for surfaces.
...
Testing it out by making a bogus TriangleMesh surface type.
2016-01-03 00:09:23 -08:00
d7f6142749
Image output now does proper sRGB correction.
2016-01-02 23:21:42 -08:00
a14a93f5a1
BVH now no longer directly references the objects it indexes.
...
Everything is done with indices anyway, so there was no reason
for it to store an internal reference to the object data. This
gets rid of the type parameter and lifetime parameter on the BVH
struct itself, which will also make it easier to bundle it with
the data it indexes, which will be important later on.
2016-01-02 22:55:20 -08:00
470618fa6a
Created a Renderer type to be in charge of rendering.
