Very happy with how well adaptive resolution is working, is super nice to not have a tradeoff between size and detail.
Quick demo of adaptivity, code is still super dumb and rebuilds the whole object on a single thread, so hopefully plenty of perf headroom left!

With thanks to the Vulkan validation layer, moving uploads/compute off the graphics queue seems to be working fine, hurrah.
With a bit of refactoring to support multiple objects, it's now fairly easy to make temporary objects for a selection effect, which helps a lot to visualise subtractive CSG:

Experimenting with directly raymarching the octree. Heirarchical traversal in compute is not too bad, and definitely nice to avoid building any additional acceleration structures.
