APIs for blackwell RT stuff came out today actually: * https://registry.khronos.org/vulkan/specs/latest/man/html/VK_NV_partitioned_acceleration_structure.html * https://registry.khronos.org/vulkan/specs/latest/man/html/VK_NV_cluster_acceleration_structure.html

Turns out OMM's are actually standardized now https://docs.vulkan.org/spec/latest/chapters/VK_EXT_opacity_micromap/micromaps.html

@Vecvec another feature request :) I've learned from https://zeux.io/2025/03/31/measuring-acceleration-structures that fp16 leads to cheaper BLAS's! Wgpu should add support for the Float16x4 (4th channel is ignored by the driver) vertex...

This might be a weird renderdoc bug, not sure. I'd like confirmation though that u32(negative_float) is always 0, or if that's not what the spec is saying.

FYI this is naga's spirv output from a wgsl shader.

Unfortunately no :(, I need a branch that builds on naga_oil for naga v24, as that's what Bevy currently uses.

I backported @robtfm's commit to naga_oil 0.17 https://github.com/JMS55/naga_oil/tree/rt-support-17, and after testing in solari I can confirm that it works. How do we want to proceed? I need a new release...

I very much want this for my Nanite clone in Bevy. * PR where I switched to using u64 atomics in buffers (plus a bunch of other stuff): https://github.com/bevyengine/bevy/pull/14623 *...

vec2u would be fine as well. I don't really have much of a preference besides "whatever is fastest".

I have a real world use case of storing a large array of vertices accessed in a compute shader https://github.com/JMS55/bevy/blob/solari/crates/bevy_solari/src/scene/scene_types.wgsl#L16-L39. I'm not sure I understand the previous discussion - are...
