Added a histogram. It accumulates the durations of all zones that have the same name as the selected one

A bit technical thread 🧵

I’ve been improving the in-game ambient occlusion system - and ended up with something I call:
Blob-based Analytical Ambient Occlusion on Primitives

Here’s what it does to the final image:
(more examples later in the thread)

(1/16)

Then if you want to provide strided arrays on top of that, there could be mesh.GetStridedVertices() that returns a struct of strided arrays for pos, normals, uvs etc.

But people can already use the VertexBufferData if they want to access vertex data without the compaction step

I don’t know, that seems like more magic to me. What’s wrong with mesh.GetPositions() and mesh.SetPositions() as a more explicit mesh.vertices?

Deprecate mesh.vertices with a message that says to use GetPositions(), but leave it in there for the next 10 years :)

Very cool to see Eike's progress on his project, and the sheer speed at which he's working. Also I find impressive how the smooth web build is. Try it!

Another attempt to upload this video to Bluesky!

Halloween is coming and there is so much left to do!

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome!

That's (apple) clang. I was already passing -Wall and -Wextra, so it seems -Wundef was not included in these. Same with zig cc.

a terminal showing a failed build with 17 errors, all pointing to mistakes such as #if __linux__

-Wundef where have you been all my life?

man this will be so good! Excited for the release

YouTube video by Vulf VULFPECK /// Tee Time

What the?? So Funky!
The rhythm and some part of the chords progression are quite close to Vulfpeck’s Tee Time, I wonder if there’s some inspiration youtu.be/iFG18LOlj-o?...

Ok! FWIW, glBeginQuery(GL_TIME_ELAPSED, ...) worked on all OpenGL core platforms I tested it on (admittedly not that many). Seems surprisingly old too (2.0)
registry.khronos.org/OpenGL-Refpa...

WebGL needs an extension: EXT_disjoint_timer_query. I didn't try it yet. Not sure about OpenGL ES.

(I had sketched a messy version of that, using a duration provided by metal in the command buffer callback, and performance counters/queries on GL and D3D. I think it would be really nice if sokol_gfx could expose GPU counter functionality for profiling, if it can be done cleanly)

On that note, have you thought about showing a frame CPU and GPU time measurement in the samples somehow? Could help to compare perf across platforms and across sokol versions

Nice! More insight on what’s going on can only be a good thing

Also, a fun experiment I did that relates to reflection:
bsky.app/profile/sebd...

Hearing that sentiment about LLVM a lot lately.
I'm also doing basic reflection for my game engine, by roughly parsing C code and emitting reflection info as code as a step before compilation. I guess that's also the direction you're going in since you mention writing a custom parser in the OP

I see! Too bad it didn't pan out, seems neat. I totally believe you for the maintenance burden. I guess it's a good cautionary tale for me, I shall not attempt to mess with llvm :D

I really wish our compiler infrastructure was less bloated and easier to handle, we could do so much more...

Perhaps in your case you could build your version of llvm in a separate repo, and copy over only the binaries you need?

Having a cross platform compiler and linker checked-in with project makes sense to me though.
Personally I check in binaries of the compiler (currently using zig cc, might move to llvm-mingw at some point to not depend on zig bugs). Do you think this is a good approach?

Truly pushing the boundaries of human knowledge there 😌

More like b[i] = (1.0f - alpha) * a[i-1] + alpha * a[i]; at this point!

Brb, adding a low pass effect to the pause menus of all my game jam games

Why did no one tell me you can implement a low pass filter in like 4 lines of C? 😤

wake up babe, new rxi lib just dropped

1 in 10 people in Gaza has now been massacred by Israel.

I love watching playtests, listening to them apologize for being bad at a game they've played for literally 1 minute, then watching them almost immediately proceed to do the sickest shit by sheer force of will.

Another puzzle idea; I am fascinated how nice the "code" of the bots look like and how it works in action, all without any collision.

Perfectly choreographed!
