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!

Anyone used DLSS-RR with ReSTIR GI before? How do you prevent DLSS-RR from thinking that correlated noise from ReSTIR GI is detail that needs to be preserved?

Added DLSS Ray Reconstruction to Bevy Solari!
It's kind of fun to look at the profile, I _think_ this is a series of upsample/downsample convolutions for a U-net, but who knows!

So subgroups are a bust, which is a shame because they were cheap. But they didn't have enough samples to reduce correlations.
So I tried workgroup-level resampling, which is mostly artifact free. Greatly improves quality! ...At double the cost (6.4->12ms) :(
Left is main, right is workgroup.

Tried doing ReSTIR spatial reuse within a subgroup today. This is the result - super good quality, but with tiling artifacts.
I tried jittering the thread ID to get subgroups to overlap across frames, and it helped a bit, but didn't entirely eliminate the artifacts :(

Added a radiance cache, and initial results show it _halved_ my ReSTIR GI time (8.62ms -> 4.32ms) in bistro! Also improved disocclusion quality a lot. The downside is that it's more temporally unstable and has some artifacts due to using a fixed sample point per voxel.

Implemented (with a lot of help) balance heuristic for ReSTIR GI spatial resampling. Spent so long fighting NaNs - turns out it was due to an unclamped dot product 🙃.
Balance heuristic helps a _ton_ though! Greatly reduces jacobian correlations, way more than rejecting jacobians does.

Just pushed a technique to avoid too many BLAS builds for continuous cluster-based LoD ray tracing. Thanks to Pyarelal Knowles whose instance merging idea was a precursor to this solution and helped on debugging.

All my raytracing shaders (compute with inline RT, not RT pipelines) have ~60% occupancy. High register count is the issue, because of the instance -> vertex/material data lookups.
Anyone know how to make this take less registers? github.com/bevyengine/b...
