What ray tracing topic should we cover next?

[mklefrancois]

We're planning the next chapter in the Vulkan Ray Tracing Tutorial series and want your input!

The tutorial currently covers 18 topics from basic ray tracing setup through advanced features like swept spheres, opacity micro-maps, and shader execution reorder. We have several advanced topics in mind for future chapters, but we'd love to know what the community is most interested in learning.
