Move shader bindings to objects rather than instances.
2022-08-07 11:05:34 -07:00
1c801ee605
PsychoBlend: implement object and material export.
...
Material bindings don't work, since they're now on the objects
themselves rather than the instances, and I haven't updated
Psychopath itself for that yet.
2022-08-07 10:23:54 -07:00
d132e6a015
Some minor cleanup in the Blender/Psychopath communication code.
2022-08-07 08:25:10 -07:00

Continue WIP update PsychoBlend for Blender 3.x.
...
It exports and renders successfully... except there are no objects.
Just a blank background.

WIP update PsychoBlend for Blender 3.x.
...
This just makes the UI not break. Exporting/rendering still
doesn't work.

Poking at what the new file/streaming format might be.

Implement "hilbert spiral" bucket rendering order.
2022-08-02 23:58:56 -07:00
7c750dcded
Directly specify bucket size instead of inferring from sample count.
...
Since we aren't doing breadth-first ray tracing anymore, this makes
a lot more sense.
2022-08-02 19:41:23 -07:00
72b8397e9d
Finished getting rid of the LightPath struct.
...
Also misc cleanup of related code.

WIP getting rid of LightPath struct.
...
Committing at this point because:
1. It compiles.
2. Rendering is totally wrong, but in a cool way.
2022-08-02 17:29:05 -07:00

Do depth-first instead of breadth-first ray tracing.
...
This simplifies a lot of code, and will make experimenting with
other things a lot more straightforward.

Minor tweaks to Owen scrambling functions.

Minor cleanup of the Owen scramble code.
2022-07-23 14:17:38 -07:00
f95e869848
Give Owen scramble functions their own hash.
...
This lets us move the seeding overhead outside the main loop,
which in turn lets us avoid taking it every round.
2022-07-23 13:24:24 -07:00
40d643b334
Put hilbert and morton code into one module.

New hash seeding approach.
...
There didn't seem to be any issues in practice with the last
approach, but I thought of some other ways things could in theory
interact badly. This fixes that.
2022-07-21 14:18:55 -07:00

Eliminate branch in per-bit Owen scrambling functions.

Noticed that z-scrambling is actually just base-4 Owen scrambling.
...
Updated function name and comments to reflect that.
2022-07-21 04:44:05 -07:00
6b7538e25f
Make the z-scrambling table smaller with bit fiddling.
...
This gets it down to 24 bytes.

Implement screen-space blue-noise sampling properly.
2022-07-21 03:59:47 -07:00
83b48f722d
Simpler way to implement screen-space blue-noise sampling.
...
We now do the index scrambling at the top of the sampling loop,
which is also faster since we only have to run it once per pixel
instead of once per sample.
2022-07-20 18:54:38 -07:00

Minor rearrangement of ray generation sampling code.
