Gotta re-download Alan Wake 2 every once in a while just to remind myself how absurdly pretty it is.

And (sorta) fixed normals on the snowbanks so the particles can slide down them properly.

This is how snow works right?

And some extremely jank SSR, everything in this scene is fudged numbers and synchronization issues.

Configurability! And lower res to maybe help with not just looking like mush after video compression.

There's ~nothing special about the particle draws, they use the "debug renderer" where you append line/cube draws to a global buffer, then a compute shader converts these draws to a giant vertex buffer.
IIIRC this is loosely based on some debug feature I remember from @mjp123.bsky.social's blog.

![HLSL Code Snippet:
g_gpuParticles[particleIndex] = particle;
// Raindrops in the air are drawn as lines in their direction of motion.
float3 startPos = particle.worldPos;
float3 endPosOrBounds = particle.worldPos + normalize(particle.velocity) * 0.4;
if (onSurface)
{
// Raindrops on surfaces are drawn as cubes.
endPosOrBounds = float3(0.1, 0.1, 0.1);
}
// Append packed command struct encoding the type + size + colour to a global list.
// A later compute shader pass reads these commands, frustum + depth culls them, then appends vertices to a single vertex buffer.
DebugDraw(
g_outputDebugDraws,
g_outputDebugDrawsCounter,
MakeDebugCommand((onSurface ? TYPE_CUBE : TYPE_LINE) | ColourToPackedBGR(float3(0, 0.6, 0.8)), startPos, endPosOrBounds));](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:jtpas3sp3y2lpimi6hbqtctj/bafkreibrf664zdido5kbgr7ip5aafs2jpxt3jd64s2uerlzj6n65gt6giu@jpeg)

Improved perf a bunch by collapsing atomics to 1 per wave, and frustum + depth culling particles before appending to the giant vertex buffer.
I think there's still some wasted time hammering a single atomic value that I could improve by splitting into N different vertex buffers instead.

Fun fact: the rain is drawn as a single (indirect) draw of 6 million vertices :)
If you open it up in PIX it looks like a point cloud of the scene:

@rebeccafernandez.bsky.social oh seems like this works!
Also makes me realize I shouldn’t be double-adding people to the GPU list with the API, even if the UI doesn’t show it…

Updated the gist to export members of followers/following that aren't included in a list, but which match a set of keywords and have made at least one post. Unfiltered data is still exported to load into other tools.

This will be my strategy going forward, dump all followers and following that aren't already in the list, search those for keywords, then manually verify. Will try to make a public sheet or something for requests so that people don't need to follow me to be included.

Ok, got this to a pretty easy place to manage, anyone have ideas for better keyword to search bios for (manually)?

Here's a very simple python gist to grab the contents of a list + followers + following in one go and dump them to CSVs. No API keys required, just need to find the list ID and your DID, which are both visible in the network requests view of your browser:
