@astrakernel.bsky.social I only skimmed the docs but I think 'atomig' (mine) can do the same, but can also use other base atomics, like u8. In case that’s important to anyone.
@chriscochrun nope, no engine, just wgpu directly.
I added some clouds to my game and tried out how they would interact with my soft shadow volume system. Turns out: quite well! Performance is problematic in a few situations but I like that it mostly just works and produces accurate shadow :)
Here is a short video showing the effect: https://www.youtube.com/watch?v=3FKNjE5G7G4
And yes, the clouds still need lots of work...
Cloud shadows via “Tiled per-triangle soft shadow volumes”
@tojiro And I assume that buffer was bound for that compute pass already anyway? That's interesting. I hardly know anything yet, but learning this is fun ^_^
@tojiro Can you share any specifics or examples? I'm also working with compute shaders more and more and optimization is an interesting topic :) One thing I learned so far is that atomics can be really slow.
Implemented ambient occlusion in the last few days. While it still needs tuning, everything already looks quite a bit nicer :)
Using a technique heavily based on SAO (scalable ambient obscurance, Morgan McGuire et al, 2012). #gamedev #graphics #wgpu #rustlang
@megmac @jamuraa You can use `pipe` from the `tap` crate: https://docs.rs/tap/1.0.1/tap/trait.Pipe.html#method.pipe
I actually use that quite a bit in production, e.g. https://github.com/elan-ev/tobira/blob/3e915dfd53704d28e3443ed45fc4a2074d68ed39/backend/src/api/model/event.rs#L264-L275
I finally managed to write a blog post about my shadow experiments, tiled soft shadow volumes :)
Really curious what others in the graphics community think.

@muvlon Exactly :)
